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.

Measurement of e+e − → K+K − π 0 cross section and observation of a resonant structure

open access: yesJournal of High Energy Physics, 2022
Based on e + e − collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e + e − → K + K − π 0.

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 ...
