Resonance enhancement of particle production during reheating [PDF]

open access: closed, 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.

STUDYING THE RESONANCE PRODUCTION CROSS-SECTION OF THE HEAVY VECTORS WITHIN HEAVY VECTOR TRIPLET MODEL [PDF]

open access: yesProblems 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]

open access: yesJournal 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 ...

Particle production from oscillating scalar field and consistency of Boltzmann equation [PDF]

open access: yesJournal of High Energy Physics, 2020
Boltzmann equation plays important roles in particle cosmology in studying the evolution of distribution functions (also called as occupation numbers) of various particles.

Hadron production in ultra-relativistic nuclear collisions and finite baryon-size effects [PDF]

open access: yesJournal 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]

open access: yes, 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.

Hadronic resonance production and interaction in partonic and hadronic matter in the EPOS3 model with and without the hadronic afterburner UrQMD [PDF]

open access: yes, 2015
We study the production of hadronic resonances and their interaction in the partonic and hadronic medium using the EPOS3 model, which employs the UrQMD model for the description of the hadronic phase.

K* 0 (892) and ϕ(1020) resonance production at RHIC [PDF]

open access: yes, 2015
The measurement of resonance production in ultrarelativistic heavy-ion colli- sions provides a glimpse of the hadronic medium properties and its evolution at different stages.

Entanglement production in the dynamical Casimir effect at parametric resonance [PDF]

open access: yesPhysical Review D, 2019
The particles produced from the vacuum in the dynamical Casimir effect are highly entangled. In order to quantify the correlations generated by the process of vacuum decay induced by moving mirrors, we study the entanglement evolution in the dynamical ...
