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.

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 ...

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.

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.

Reheating in the Presence of Noise [PDF]

open access: yes, 1997
Explosive particle production due to parametric resonance is a crucial feature of reheating in inflationary cosmology. Coherent oscillations of the inflaton field act as a periodically varying mass in the evolution equation for matter fields which couple

Measurements of the pp → W± γγ and pp → Zγγ cross sections at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV and limits on anomalous quartic gauge couplings

open access: yesJournal of High Energy Physics, 2021
The cross section for W or Z boson production in association with two photons is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV.

Heavy resonance production in high energy nuclear collisions [PDF]

open access: yes, 1994
We estimate freezeout conditions for $s$, $c$, and $b$ quarks in high energy nuclear collisions. Freezeout is due either to loss of thermal contact, or to particles ``wandering'' out of the region of hot matter.

Search for sub-eV axion-like resonance states via stimulated quasi-parallel laser collisions with the parameterization including fully asymmetric collisional geometry

open access: yesJournal of High Energy Physics, 2021
We have searched for axion-like resonance states by colliding optical photons in a focused laser field (creation beam) by adding another laser field (inducing beam) for stimulation of the resonance decays, where frequency-converted signal photons can be ...
