Possible anomalous New Physics contributions to dipole and weak dipole moments of the tau lepton bring renewed interest in development and revisiting charge-parity violating signatures in the tau-pair production in Z-boson decay at energies of the Large Hadron Collider.
Effects of anomalous contributions on polarization and spin correlations of the tau leptons, in the production process q...
In this report we present the macroscopic model for neutron stars (NSs) described as a perfect cold liquid
drop at equilibrium within the Tolman-Oppenheimer-Volkoff theory modified by the Kerr and Hartle
approaches for slow azimuthal angular frequency around the symmetry axis. We take into account the NS
surface deformation within the leptodermic approximation [1]. Introducing the...
Based on numerical simulations of 6 GeV electron propagation through bent crystals with various orientations relative to the incident particle direction, as well as different bending radii and crystal thicknesses, we performed a comparative analysis of the deflection efficiency in planar and axial crystal orientations. To identify the optimal bent crystal parameters for maximum electron...
The Higgs boson discovery raised new questions about the Standard Model's mysteries, particularly the existence of three matter generations with vastly different masses. New physics might be revealed through electron-positron collider experiments at specific energy levels, as the Standard Model serves as a foundation for examining nature across all scales .
An extended scalar sector enables a...
One of the main goals of relativistic heavy-ion experiments in the GeV range is to explore the QCD phase diagram, particularly at high baryon chemical potential, where critical features may emerge. At very high energies, such as at the LHC, the matter created is extremely hot with low net baryon density, and lattice QCD indicates a smooth crossover from quark–gluon plasma to hadronic matter....

$1.$ $Introduction.$ A new multi-parameter score-rating methodology for assessing the quality of theoretical description of experimental data in heavy-ion physics [1-11] is proposed. The...
The production of gauge fields during inflation has a wide range of phenomenological implications. It can affect the background dynamics of inflation, modify the spectral properties of primordial scalar and tensor perturbations, and lead to the creation of charged particles through the Schwinger effect. The latter can significantly suppress the efficiency of gauge-field production during...
