Resonance enhancement of particle production during reheating [PDF]
, 2001 We found a consistent equation of reheating after inflation which shows that for small quantum fluctuations the frequencies of resonance are slighted different from the standard ones.

Particle production and equilibrium properties within a new hadron transport approach for heavy-ion collisions [PDF]
, 2016 The microscopic description of heavy-ion reactions at low beam energies is achieved within hadronic transport approaches. In this article a new approach SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) is introduced and applied to study ...

Preheating after multifield inflation with nonminimal couplings, II: Resonance Structure [PDF]
, 2018 This is the second in a series of papers on preheating in inflationary models comprised of multiple scalar fields coupled nonminimally to gravity. In this paper, we work in the rigid-spacetime approximation and consider field trajectories within the ...

STUDYING THE RESONANCE PRODUCTION CROSS-SECTION OF THE HEAVY VECTORS WITHIN HEAVY VECTOR TRIPLET MODEL [PDF]
Problems of Atomic Science and Technology, 2023 In the context of TeV-scale extensions of the Standard Model both the experimental data and the construction of phenomenological models for the new heavy bosons searches are used by us.

Superadiabatic basis in cosmological particle production: application to preheating [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We discuss the adiabatic basis dependence of particle number in time-dependent backgrounds. In particular, we focus on preheating after inflation, and show that, for the optimal basis, the time dependence of the produced particle number can be well ...

Hadron production in ultra-relativistic nuclear collisions and finite baryon-size effects [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2023 We investigate the relative yields of various like and unlike mass hadrons in ultra-relativistic heavy-ion collisions (URHIC). In the framework of thermal model a strong evidence of strangeness imbalance is observed in the experiments at lower ...

Resonance production in high energy collisions from small to big systems [PDF]
, 2017 The aim of this paper is to understand resonance production (and more generally particle production) for different collision systems, namely proton-proton (pp), proton-nucleus (pA), and nucleus-nucleus (AA) scattering at the LHC.
