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.

The canonical partition function for relativistic hadron gases [PDF]

open access: yes, 2009
Particle production in high-energy collisions is often addressed within the framework of the thermal (statistical) model. We present a method to calculate the canonical partition function for the hadron resonance gas with exact conservation of the baryon

Study of η(1405)/η(1475) in J / ψ → γ K S 0 K S 0 π 0 $$ J/\psi \to \gamma {K}_S^0{K}_S^0{\pi}^0 $$ decay

open access: yesJournal of High Energy Physics, 2023
Using a sample of (10.09 ± 0.04) × 109 J/ψ decays collected with the BESIII detector, partial wave analyses of the decay J / ψ → γ K S 0 K S 0 π 0 $$ J/\psi \to \gamma {K}_S^0{K}_S^0{\pi}^0 $$ are performed within the K S 0 K S 0 π 0 $$ {K}_S^0{K}_S^0 ...

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

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 ...

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.

Determination of the strong coupling constant α S(mZ) from measurements of inclusive W ± and Z boson production cross sections in proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 7 and 8 TeV

open access: yesJournal of High Energy Physics, 2020
Twelve measurements of inclusive cross sections of W ± and Z boson production, performed in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, are compared with perturbative quantum chromodynamics calculations at next-to-next- to-leading
