Helical separation effect and helical heat transport for Dirac fermions Eur. Phys. J. C (IF 4.4) Pub Date : 2024-03-18 Victor E. Ambruş, Maxim N. Chernodub
An ensemble of massless fermions can be characterized by its total helicity charge given by the sum of axial charges of particles minus the sum of axial charges of antiparticles. We show that charged massless fermions develop a dissipationless flow of helicity along the background magnetic field. We dub this transport phenomenon as the Helical Separation Effect (HSE). Contrary to its chiral cousin

Revisiting the dynamics of interacting vector-like dark energy Eur. Phys. J. C (IF 4.4) Pub Date : 2024-03-17
Abstract We revise the dynamics of interacting vector-like dark energy, a theoretical framework proposed to explain the accelerated expansion of the universe. By investigating the interaction between vector-like dark energy and dark matter, we analyze its effects on the cosmic expansion history and the thermodynamics of the accelerating universe. Our results demonstrate that the presence of interaction

Little rip, pseudo rip and bounce cosmology with generalized equation of state in non-standard backgrounds Eur. Phys. J. C (IF 4.4) Pub Date : 2024-03-17 Oem Trivedi, Alexander V. Timoshkin
The discovery of universe’s late-time acceleration and dark energy has overseen a great deal of research into cosmological singularities and particularly future singularities. Perhaps the most extreme of such singlarities is the big rip, which has propelled a lot of work into ways of moderating it or seeking out alternatives to it and two such alternatives to the big rip are the Little rip and Pseudo

Electric and dilatonic fields of a charged massive particle at rest in the field of a charged dilaton black hole Eur. Phys. J. C (IF 4.4) Pub Date : 2024-03-17
Abstract We study linear-perturbation equations for the two-body system of a charged dilaton black hole, of which dilaton coupling constant is \(\alpha \) , and a static particle with mass m, electric charge q, and dilatonic charge \(\beta m\) . We find that a consistent condition for the coupled equations corresponds to the equilibrium condition of the test particle. The expressions of classical fields

The Low soft-photon theorem again Eur. Phys. J. C (IF 4.4) Pub Date : 2024-03-15 V. S. Fadin, V. A. Khoze
It is shown that contrary to claims of Lebiedowicz et al. (Phys Rev D 105(1):014022, 2022) the formulated in the proper physical variables Low theorem (Low in Phys Rev 110(4):974–977, 1958) for soft photon emission does not require any modification. We also reject the criticism in Lebiedowicz et al. (2022) of the papers (Bell and Van Royen in Nuovo Cim A 60:62–68, 1969; Lipatov in Nucl Phys B 307:705–720

Back-reaction of long-wavelength cosmological fluctuations as measured by a clock field Eur. Phys. J. C (IF 4.4) Pub Date : 2024-03-15 Vincent Comeau, Robert Brandenberger
We consider the back-reaction of cosmological fluctuations on the local expansion rate averaged over a space-like hypersurface of constant value of a clock field. We show that in the infrared limit, the fluctuations lead to a decrease in the average expansion rate, measured at a fixed value of the clock field, compared to what would be obtained in a homogeneous universe. We work in the context of Einstein

The telltale signal providing a unique signature of such particles, would be a correlated sequence of three or more nuclear recoils along a straight line, corresponding

Abstract A high-statistics data sample of the \(K^{+}\) decays is recorded by the OKA collaboration. A missing mass analysis is performed to search for a light invisible pseudoscalar axion-like particle (ALP) a in the decay \(K^{+} \rightarrow \pi ^{+} \pi ^{0} a\) . No signal is observed, and the upper limits for the branching ratio of the decay are calculated. The \(90\%\) confidence level upper

Abstract At the Paul Scherrer Institut (PSI), we are developing a high-precision apparatus with the aim of searching for the muon electric dipole moment (EDM) with unprecedented sensitivity. The underpinning principle of this experiment is the frozen-spin technique, a method that suppresses the spin precession due to the anomalous magnetic moment, thereby enhancing the signal-to-noise ratio for EDM

This model comprises particles in a nonequilibrium cylindrical distribution, which

The dynamic hadronization of charm quarks in heavy-ion collisions Eur. Phys. J. C (IF 4.4) Pub Date : 2024-03-05
Abstract The Pythia8/Angantyr model for heavy ion collisions was recently updated with a mechanism for global colour reconnection. The colour reconnection model used is QCD colour algebra inspired and enhances baryon production due to the formation of string junctions. In this paper, we present updates to the junction formation and string fragmentation mechanisms, connected to heavy quark fragmentation

We employ a simplified model to describe the
