Casimir force on a light front Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-11-21 S.S. Chabysheva; J.R. Hiller
Depending on the point of view, the Casimir force arises from variation in the energy of the quantum vacuum as boundary conditions are altered or as an interaction between atoms in the materials that form these boundary conditions. Standard analyses of such configurations are usually done in terms of ordinary, equal-time (Minkowski) coordinates. However, physics is independent of the coordinate choice

Precision physics with inclusive QCD processes Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-12-26 Antonio Pich
The inclusive production of hadrons through electroweak currents can be rigorously analysed with short-distance theoretical tools. The associated observables are insensitive to the involved infrared behaviour of the strong interaction, allowing for very precise tests of Quantum Chromodynamics. The theoretical predictions for σ(e+e−→hadrons) and the hadronic decay widths of the τ lepton and the Z, W

Quenching of single-particle strength from direct reactions with stable and rare-isotope beams Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2021-01-07 T. Aumann; C. Barbieri; D. Bazin; C.A. Bertulani; A. Bonaccorso; W.H. Dickhoff; A. Gade; M. Gómez-Ramos; B.P. Kay; A.M. Moro; T. Nakamura; A. Obertelli; K. Ogata; S. Paschalis; T. Uesaka
In this review article we discuss the present status of direct nuclear reactions and the nuclear structure aspects one can study with them. We discuss the spectroscopic information we can assess in experiments involving transfer reactions, heavy-ion-induced knockout reactions and quasifree scattering with (p,2p), (p,pn), and (e,e′p) reactions. In particular, we focus on the proton-to-neutron asymmetry

What comes after the Standard Model? Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-10-10 M. Khlopov
The standard model (SM) of elementary particles involves particle symmetry and the mechanism of its breaking. It finds no contradictions in the collider experiments, but appeals to extensions for solutions of its internal problems and in view of its evident incompleteness. The paradigm of the modern cosmology is based on inflationary models with baryosynthesis and dark matter/energy that involves physics

Color screening in quantum chromodynamics Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-09-28 Alexei Bazavov; Johannes Heinrich Weber
We review lattice studies of the color screening in the quark–gluon plasma. We put the phenomena related to the color screening into the context of similar aspects of other physical systems (electromagnetic plasma or cold nuclear matter). We discuss the onset of the color screening and its signature and significance in the QCD transition region, and elucidate at which temperature and to which extent

The last decade has seen a marked shift in how the internal structure of hadrons is understood. Modern experimental facilities, new theoretical techniques for the continuum bound-state problem and progress with lattice-regularised QCD have provided strong indications that soft quark+quark (diquark) correlations play a crucial role in hadron physics. For example, theory indicates that the appearance

Recent progress in laser spectroscopy of the actinides Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-10-10 Michael Block; Mustapha Laatiaoui; Sebastian Raeder
The interest to perform laser spectroscopy in the heaviest elements arises from the strong impact of relativistic effects, electron correlations and quantum electrodynamics on their atomic structure. Once this atomic structure is well understood, laser spectroscopy also provides access to nuclear properties such as spins, mean-square charge radii and electromagnetic moments in a nuclear-model independent

Quantum causality and the arrows of time and thermodynamics Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-08-06 John F. Donoghue; Gabriel Menezes
In the understanding of the fundamental interactions, the origin of an arrow of time is viewed as problematic. However, quantum field theory has an arrow of causality, which tells us which time direction is the past lightcone and which is the future. This direction is tied to the conventions used in the quantization procedures. The different possible causal directions have related physics — in this

Strongly coupled theories beyond the Standard Model Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-08-07 Antonio Dobado; Domènec Espriu
This article presents a number of technical tools and results that may be instrumental to discern the nature of the Higgs particle. In scenarios where an additional strongly interacting sector is present in the electroweak theory, resulting in a composite Higgs and longitudinal components of the massive gauge bosons, unitarity, analyticity and related techniques will be crucial to understand the properties

Exascale computing could soon enable a predictive theory of nuclear structure and reactions rooted in the Standard Model, with quantifiable and systematically improvable uncertainties. Such a predictive theory will help exploit experiments that use nucleons and nuclei as laboratories for testing the Standard Model and its limitations. Examples include direct dark matter detection, neutrinoless double

Transverse spin effects in hard semi-inclusive collisions Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-06-16 M. Anselmino, A. Mukherjee, A. Vossen
The nucleons (protons and neutrons) are by far the most abundant form of matter in our visible Universe; they are composite particles made of quarks and gluons, the fundamental quanta of Quantum Chromo Dynamics (QCD). The usual interpretation of the nucleon dynamics in high energy interactions is often limited to a simple one-dimensional picture of a fast moving nucleon as a collection of co-linearly

We review the current understanding of heavy quark parton distributions in nucleons and their impact on deep inelastic scattering, collider physics, and other processes at high energies. The determination of the heavy-quark parton distribution functions is particularly significant for the analysis of hard processes at LHC energies, including the forward rapidity high xF domain.

Search for neutrino-less double beta decay with thermal detectors Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-06-11 M. Biassoni, O. Cremonesi
Neutrino-less double-beta decay (0νββ) is a hypothetical nuclear transition which violates lepton-number conservation and is therefore forbidden by the Standard Model of particle physics. Its observation would unambiguously demonstrate that neutrinos are Majorana particles and would provide unique information about the ordering and absolute scale of neutrino masses. This would have fundamental implications

We construct a generalized effective field theory approach to dense compact-star matter that exploits the Cheshire Cat Principle for hadron–quark continuity at high density, adhering only to hadronic degrees of freedom, hidden topology and hidden symmetries of QCD. No Landau–Ginzburg–Wilsonian-type phase transition is involved in the range of densities involved. The microscopic degrees of freedom of

Status of the determination of the electron–neutrino mass Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-05-13 Amand Faessler
(1) The classical way to determine the electron anti-neutrino mass is the single Beta Decay of Tritium [3H → 3He + e− + νec] (Particle Physics Booklet, 2014; Aker et al., 2019). This special decay is favored by the small Q-value Q=18.5737 ± 0.00025 keV (Aker et al., 2019). Presently KATRIN (Aker et al., 2019) yields an upper limit of 1.1 eV (90% CL) for the neutrino mass the best result. (2) Electron

Despite decades of research, we still lack a detailed quantitative understanding of the way quantum chromodynamics (QCD) generates the spectrum of hadrons. Precise experimental studies of the hadron excitation spectrum and the dynamics of hadrons help to improve models and to test effective theories and lattice QCD simulations. In addition, QCD seems to allow hadrons beyond the three-quark and quark–antiquark

The spectrum of hadrons is the manifestation of color confinement of quantum chromodynamics. Hadronic resonances correspond to poles of the S-matrix. Since 2003, lots of new hadron resonant structures were discovered in the mass regions from light mesons to hadrons containing a pair of a heavy quark and an antiquark. Many of them are candidates of exotic hadrons, and they are usually observed as peaks

Emergent gauge symmetries and particle physics Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2020-01-30 Steven D. Bass
Hadron properties and interactions are emergent from QCD. Atomic and condensed matter physics are emergent from QED. Could the local gauge symmetries of particle physics also be emergent? We give an introduction to this question and recent ideas connecting it to the (meta)stability of the Standard Model Higgs vacuum. With an emergent Standard Model the gauge symmetries would “dissolve” in the ultraviolet

Cosmic ray models Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2019-07-24 M. Kachelrieß, D.V. Semikoz
We review progress in high-energy cosmic ray physics focusing on recent experimental results and models developed for their interpretation. Emphasis is put on the propagation of charged cosmic rays, covering the whole range from ∼(20–50) GV, i.e. the rigidity when solar modulations can be neglected, up to the highest energies observed. We discuss models aiming to explain the anomalies in Galactic cosmic

Relativistic hydrodynamics for spin-polarized fluids Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2019-07-24 Wojciech Florkowski, Avdhesh Kumar, Radoslaw Ryblewski
Recent progress in the formulation of relativistic hydrodynamics for particles with spin one-half is reviewed. We start with general arguments advising introduction of a tensor spin chemical potential that plays a role of the Lagrange multiplier coupled to the spin angular momentum. Then, we turn to a discussion of spin-dependent distribution functions that have been recently proposed to construct

Interplay of neutron–proton equilibration and nuclear dynamics Prog. Part. Nucl. Phys. (IF 13.421) Pub Date : 2019-06-13 Alan B. McIntosh, Sherry J. Yennello
Neutron–proton equilibration in heavy-ion collisions proceeds atop a landscape of deformed topography and large density changes. The rapidly-varying landscape is created by the collision dynamics. The collision dynamics influences the neutron–proton equilibration, but just as importantly the different migration of the protons and neutrons influences the dynamics. To fully appreciate either the reaction
