Resonance enhancement of particle production during reheating [PDF]

open access: yesClassical 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. Quantum interference is taken into account and we found that at large fluctuations the process mimics very well the usual parametric resonance but proceed in a different

Resonant particle production in branonium [PDF]

open access: yesPhysical Review D, 2008
We study the mechanism of particle production in the world-volume of a probe anti D6-brane (or D6 with SUSY breaking) moving in the background created by a fixed stack of $D6$-branes. We show that this may occur in a regime of parametric resonance when the probe's motion is non-relativistic and it moves at large distances from the source branes in low ...

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

Search for sub-eV axion-like particles in a stimulated resonant photon-photon collider with two laser beams based on a novel method to discriminate pressure-independent components

open access: yesJournal of High Energy Physics, 2022
Sub-eV axion-like particles (ALPs) have been searched for by focusing two-color near-infrared pulse lasers into a vacuum along a common optical axis. Within the focused quasi-parallel collision system created by combining a creation field (2.5 mJ/47 fs ...

Resonant particle production during inflation: a full analytical study [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2017
We revisit the study of the phenomenology associated to a burst of particle production of a field whose mass is controlled by the inflaton field and vanishes at one given instance during inflation. This generates a bump in the correlators of the primordial scalar curvature.

Measurement of the inclusive production of neutral pions and charged particles on the Z0 resonance [PDF]

open access: yesPhysics Letters B, 1991
Abstract We present a study of the inclusive production of neutral pions and charged particles from 112 000 hadronic Z 0 decays. The measured inclusive momentum distributions can be reproduced by parton shower Monte Carlo programs and also by an analytical QCD calculation.
