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.

Particle production at energies available at the CERN Large Hadron Collider within evolutionary model [PDF]

open access: yesPhysical Review C, 2018
The particle yields and particle number ratios in Pb+Pb collisions at the LHC energy $\sqrt{s_{NN}}=2.76$ TeV are described within the integrated hydrokinetic model (iHKM) at the two different equations of state (EoS) for the quark-gluon matter and the ...

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.

Particle production and equilibrium properties within a new hadron transport approach for heavy-ion collisions [PDF]

open access: yes, 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]

open access: yes, 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]

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.

Measurement of the B ± production cross-section in pp collisions at s=7 $$ \sqrt{s}=7 $$ and 13 TeV

open access: yesJournal of High Energy Physics, 2017
The production of B ± mesons is studied in pp collisions at centre-of-mass energies of 7 and 13 TeV, using B ± → J/ψ K ± decays and data samples corresponding to 1.0 fb−1 and 0.3 fb−1, respectively.

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.
