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 ...

Probing Planckian physics: resonant production of particles during inflation and features in the primordial power spectrum [PDF]

open access: yesPhysical Review D, 1999
The phenomenon of resonant production of particles {\it after} inflation has received much attention in the past few years. In a new application of resonant production of particles, we consider the effect of a resonance {\em during} inflation.

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 ...

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.

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 heavy resonances decaying to ZZ or ZW and axion-like particles mediating nonresonant ZZ or ZH production at $$ \sqrt{s} $$ = 13 TeV [PDF]

open access: yesJournal of High Energy Physics, 2022
Abstract A search has been performed for heavy resonances decaying to ZZ or ZW and for axion-like particles (ALPs) mediating nonresonant ZZ or ZH production, in final states with two charged leptons (ℓ = e, μ) produced by the decay of a Z boson, and two quarks produced by the decay of a Z, W, or Higgs boson H.

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 ...
