Resonance enhancement of particle production during reheating [PDF]

open access: closedClassical and Quantum Gravity, 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.

Resonance production in high energy collisions from small to big systems [PDF]

open access: yesEPJ Web of Conferences, 2018
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.

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 ...

Search for an axion-like particle with forward proton scattering in association with photon pairs at ATLAS [PDF]

open access: yesJournal of High Energy Physics, 2023
A search for forward proton scattering in association with light-by-light scattering mediated by an axion-like particle is presented, using the ATLAS Forward Proton spectrometer to detect scattered protons and the central ATLAS detector to detect pairs ...

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 ...

Search for new phenomena in multi-body invariant masses in events with at least one isolated lepton and two jets using s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data collected by the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for resonances in events with at least one isolated lepton (e or μ) and two jets is performed using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data recorded by the ATLAS detector at the LHC. Deviations from a smoothly falling

Measurement of e + e − → ωπ + π − cross section at s $$ \sqrt{s} $$ = 2.000 to 3.080 GeV

open access: yesJournal of High Energy Physics, 2023
A partial wave analysis on the process e + e − → ωπ + π − is performed using 647 pb −1 of data sample collected by using the BESIII detector operating at the BEPCII storage ring at center-of-mass (c.m.) energies from 2.000 GeV to 3.080 GeV.
