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 ...

Stability and Free Radical Production for CO2 and H2 in Air Nanobubbles in Ethanol Aqueous Solution

open access: yesNanomaterials, 2022
In this study, 8% hydrogen (H2) in argon (Ar) and carbon dioxide (CO2) gas nanobubbles was produced at 10, 30, and 50 vol.% of ethanol aqueous solution by the high-speed agitation method with gas.

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

Lattice QCD Thermodynamics and RHIC-BES Particle Production within Generic Nonextensive Statistics [PDF]

open access: yesPhysics of Particles and Nuclei Letters, 2017
The current status of implementing Tsallis (nonextensive) statistics on high-energy physics is briefly reviewed. The remarkably low freezeout-temperature, which apparently fails to reproduce the firstprinciple lattice QCD thermodynamics and the measured ...

Multi-Step Production of a Diphoton Resonance [PDF]

open access: yes, 2016
Among the questions that would be raised by the observation of a new resonance at the LHC, particularly pressing are those concerning the production mechanism: What is the initial state?

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 ...

Twisted particle collisions: A new tool for spin physics [PDF]

open access: yes, 2020
Collisions of twisted particles --- that is, non-plane-wave states of photons, electrons, or any other particle, equipped with a non-zero orbital angular momentum (OAM) with respect to its propagation direction --- offer novel ways to probe particle ...

Observation of e + e − → ηψ(2S) at center-of-mass energies from 4.236 to 4.600 GeV

open access: yesJournal of High Energy Physics, 2021
Using a total of 5.25 fb −1 of e + e − collision data with center-of-mass energies from 4.236 to 4.600 GeV, we report the first observation of the process e + e − → ηψ(2S) with a statistical significance of 4.9 standard deviations.
