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 ...

Search for heavy resonances decaying to ZZ or ZW and axion-like particles mediating nonresonant ZZ or ZH production at s? = 13 TeV

open access: yes, 2022
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 (? = e, ?) produced by the decay of a Z boson, and two quarks produced by the decay of a Z, W, or Higgs boson H. The analysis is sensitive to resonances with masses

Observation of e + e − → π 0 π 0 ψ 2(3823)

open access: yesJournal of High Energy Physics, 2023
Using a data sample corresponding to an integrated luminosity of 11.3 fb −1 collected at center-of-mass energies from 4.23 to 4.70 GeV with the BESIII detector, we observe the process e + e − → π 0 π 0 ψ 2(3823) for the first time with a statistical ...

Particle production in the oscillating inflation model [PDF]

open access: yes, 2000
We investigate the particle production of a scalar field $\chi$ coupled to an inflaton field $\phi$ ($g^2\phi^2\chi^2/2$) in the {\it oscillating inflation} model, which was recently proposed by Damour and Mukhanov. Although the fluctuation of the $\phi$
