Many decays of light baryons consisting of light u , d , s quarks have been measured, and these measurements will help us to understand the decay properties of light baryons. In this work, we study two-body nonleptonic weak decays of light baryon octets ( T 8 ) and baryon decuplets ( T 10 ) by the topological diagram approach (TDA) under the SU(3) flavor symmetry for the first time. We find that (1)

The quark matter symmetry free energy and the thermodynamical properties of strange quark matter (SQM) in strong magnetic fields and non-zero temperature cases are discussed in this work within Nambu–Jona-Lasinio (NJL) model by considering two kinds of vector interactions. The properties of the proto-quark stars (PQSs) are also studied by introducing a density-dependent magnetic field strength distribution

High-spin states of 109 Ag have been studied using the 7 Li + 110 Pd reaction at a beam energy of 46 MeV. A negative-parity band decaying to the ground-state band by several new linking transitions is established. Meanwhile, seven new E 2 crossover transitions of this band are observed, thereby confirming the spin-parity assignment and ordering of the dipole transitions above the I π = 19/2 − level

The study of exotic nuclei is one of the most interesting topics in nuclear physics. 34 Na has attracted additional attentions for an odd–odd nucleus with special structure. Here, we combine the complex momentum representation (CMR) and Green’s function (GF) to establish the CMR-GF method for the exploration of exotic structure, such as halo, skin, the level inversion and so on, in 34 Na. The available

This work reports, for the first time, the analysis of tensor analyzing powers ( T 20 , T 21 , T 22 ) along with the differential cross-section (CS) and the vector analyzing power iT 11 for the 6 Li + 12 C elastic scattering at 30 and 50 MeV within the framework of an optical model (OM) using microscopic shallow non-monotonic (NM) potentials. The NM potential is generated from the energy density functional

In this work, the CPT-violating (CPTV) interactions on neutrons’ gravitational bound state are studied. With simple analytical solutions, we provide a preliminary investigation into the Lorentz-violation (LV)-induced spin precession due to the ##IMG## [http://ej.iop.org/images/0954-3899/47/8/085002/gab8c30ieqn1.gif] {$\to {\sigma }\cdot \to {\tilde {b}}\left(1+gz\right)$} and ##IMG## [http://ej.iop

We investigate the hindrance of the unfavored α -decay modes to the different daughter states, which have different spin than that of the parent nucleus but of the same parity. The duplicated daughter nucleus states of identical spin-parity ( J π ) are ascendingly ordered according to the sequence of their excitation energy. We found that the hindrance of the unfavored decay modes increases with increasing

We investigate baryogenesis via leptogenesis in an A 4 flavor model within the paradigm of type-I and II seesaw mechanism resulting in a magic neutrino mass matrix with broken μ − τ symmetry in a minimal scenario with two right-handed neutrinos (2RHN). Additional Z 3 cyclic symmetry is employed to constrain the Yukawa structure of the model. The type-II seesaw terms play a crucial role in generating

Properties of b-baryon decay matrix elements (amplitudes) are derived in a nonsymmetric quark model without any use of SU(6), SU(3), or SU(2) (isotopic spin) groups. Equalities between pairs of atrix elements are derived, and Λ–Σ mixing is used to calculate the branching ratio for the transition Λ b → Σ 0 .

The Cu + Au collisions are expected to provide interesting new aspects in the understanding of anisotropic flow in heavy ion collisions due to asymmetric initial geometry on the transverse plane as well as due to the significant difference in number of participants in the two colliding nuclei. We calculate directed flow coefficient v 1 of thermal photons from 200 A GeV Cu + Au collisions at RHIC using

We consider neutrino oscillations in vacuum in the framework of quantum field theory in which neutrino production and detection processes are part of a single Feynman diagram and the corresponding cross section is computed in the standard way, i.e. with final states represented by plane waves. We use assumptions which are realized in actual experiments and concentrate on the detection process. Moreover

In this paper, we explore the signature of a simplified model which includes a new singlet scalar state and a vector like quark at future lepton colliders. In particular, we study the production of the new singlet scalar in association with a photon, which proceeds through loop level diagrams involving a vector like top quark partner, at future e − e + colliders with different center-of-mass energies

Nuclear density functional theory is the prevalent theoretical framework for accurately describing nuclear properties at the scale of the entire chart of nuclides. Given an energy functional and a many-body scheme (e.g., single- or multireference level), the predictive power of the theory depends strongly on how the parameters of the energy functionals have been calibrated with experimental data. Expanded

The dinuclear system (DNS) model has been widely used to explain different heavy-ion reactions such as fusion, quasifission and fission. In previous studies, the DNS is treated as a local N / Z equilibrium system formed after the capture process in the final stage of the reaction. In this work, we generalize the DNS concept to describe the multi-nucleon transfer (MNT) reaction in the dynamical radial

By allowing gauge anomaly cancellation between fermions in different families we find a non-universal solution for a Z ′ family of models with the same content of fermions of the standard model plus three right-handed neutrinos. We also impose constraints from the Yukawa interaction terms in such a way that at the end we obtain a solution with six free parameters. Our solution contains as particular

The direct photon emission model in relativistic nuclear colliders has been improved in recent years for reducing the discrepancy between theoretical estimations and experimental data and for understanding the properties of the QCD matter. In this study, the contribution of pre-equilibrium photons are investigated in addition to those of prompt and thermal photons in the framework of a relativistic

The cross-sections of 153 Eu(n,p) 153 Sm and 153 Eu(n,α) 150 Pm reactions have been measured experimentally. Monoenergetic neutron beams were produced via the 3 H(d,n) 4 He reaction using the K-400 neutron generator at China Academy of Engineering Physics (CAEP). The activity of the reaction products were measured using high-resolution gamma-ray spectroscopy. Using the 27 Al(n,α) 24 Na reaction as

Simple extensions of the standard model (SM) with additional right handed neutrinos (RHNs) can elegantly explain the existence of small neutrino masses and their flavor mixings. Collider searches for sterile neutrinos are being actively pursued currently. Heavy RHNs may dominantly decay into ##IMG## [http://ej.iop.org/images/0954-3899/47/7/075002/jpgab7769ieqn1.gif] {${W}^{\pm }{{\ell }}^{\mp }$} after

The Dirac–Sommerfeld–Maue theory for relativistic electron–nucleus bremsstrahlung at the short-wavelength limit is extended to cover an energy range from 0 to 3 MeV of the outgoing electron, irrespective of collision energy. This is achieved by using an asymptotic representation of the Sommerfeld–Maue function for the impinging electron, valid at energies above 50 MeV, as well as a partial-wave expansion

136 Xe is used as the target medium for many experiments searching for 0 νββ . Despite underground operation, cosmic muons that reach the laboratory can produce spallation neutrons causing activation of detector materials. A potential background that is difficult to veto using muon tagging comes in the form of 137 Xe created by the capture of neutrons on 136 Xe. This isotope decays via beta decay with

The evolution of non-axial shapes and rotational structure in even–even 122–132 Ba isotopes has been investigated microscopically with the application of a triaxial projected shell model (TPSM). Based on calculations, the shape instability and softness towards γ deformation are predicted for these isotopes. In the present work, the application of three-dimensional angular-momentum projection on multi-quasiparticle

We investigate the nuclear modification factor ( R AA ) of identified particles as a function of transverse momentum ( p T ) in Pb–Pb collisions at ##IMG## [http://ej.iop.org/images/0954-3899/47/7/075101/gab8744ieqn1.gif] {$\sqrt{{s}_{\text{NN}}}=$} 2.76 and 5.02 TeV, as well as p-Pb collision at 5.02 TeV in the framework of Boltzmann transport equation with relaxation time approximation. In this framework

This document summarises proposed searches for new physics accessible in the heavy-ion mode at the CERN Large Hadron Collider (LHC), both through hadronic and ultraperipheral γγ interactions, and that have a competitive or, even, unique discovery potential compared to standard proton–proton collision studies. Illustrative examples include searches for new particles—such as axion-like pseudoscalars

In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous 83m Kr with the Karlsruhe Tritium Neutrino (KATRIN) experiment. The obtained results represent one of the major commissioning milestones for the subsequent direct neutrino mass measurement with KATRIN. The successful campaign demonstrates the functionalities of the

In this article we have explored the possibility of measuring the proton induced fission cross sections using surrogate reaction method. To establish the validity of the surrogate method, we have derived the cross sections for 240 Pu( p , f ), 234 Th( p , f ), 236 U( p , f ) and 233 Th( p , f ) reactions using the derived cross section data of 240 Am( n , f ), 234 Pa( n , f ), 236 Np( n , f ) and 233

The multi-nucleon transfer process is a promising approach for producing neutron-rich heavy nuclei. Its favorable projectile-target combinations play a key role in experiments. As an important theoretical approach to investigate the multi-nucleon transfer process, the dinuclear system (DNS) model is improved and shown in detail. Based on the degree of freedom of the deformation of the improved DNS

Calculations of absorption cross sections using a microscopic first-order optical potential for heavy-ion scattering are compared with experiments. In-medium nucleon-nucleon (NN) cross sections were used to calculate the two-body scattering amplitude. A medium-modified first-order optical potential was obtained for heavy-ion scattering using the in-medium two-body scattering amplitude. A partial wave

The production of protons in heavy ion collisions through the knockout mechanism (abrasion) is described using the Glauber model. The multiple knockouts from the projectile, including the inelastic collision series with the target, are considered using a closure approximation in treating energy conservation. Calculations for reactions of 12C projectiles with several targets at energies of 1 and 2A

We consider the inclusive inelastic scattering of heavy ions using the Glauber model and the independent particle approximation. Inclusive inelastic distributions for projectile excitation of the target and total inelastic scattering, where all projectile and target excited states are summed, are discussed using closure. The total inelastic distribution when integrated is shown to be equivalent to
