Production of cascade hypernuclei via the (K-,K+) reaction within a quark-meson coupling model

open access: yes, 2012
We study the production of bound cascade hypernuclei via the (K-,K+) reaction on 12C and 28Si targets within a covariant effective Lagrangian model, employing the cascade bound state spinors derived from the latest quark-meson coupling model as well as ...

Production of Dark Sector Particles via Resonant Positron Annihilation on Atomic Electrons

open access: yesPhysical Review Letters
Resonant positron annihilation on atomic electrons provides a powerful method to search for light new particles coupled to e+e−. Reliable estimates of production rates require a detailed characterization of electron momentum distributions. We describe a general method that harnesses the target material Compton profile to properly include electron ...

Measurement of Born cross sections of e + e − → Ξ 0 Ξ ¯ 0 $$ {e}^{+}{e}^{-}\to {\Xi}^0{\overline{\Xi}}^0 $$ and search for charmonium(-like) states at s $$ \sqrt{s} $$ = 3.51–4.95 GeV

open access: yesJournal of High Energy Physics
Using e + e − collision data collected by the BESIII detector at BEPCII corresponding to an integrated luminosity of 30 fb −1, we measure Born cross sections and effective form factors for the process e + e − → Ξ 0 Ξ ¯ 0 $$ {e}^{+}{e}^{-}\to {\Xi}^0 ...

Resonances as Probes of Heavy-Ion Collisions at ALICE

open access: yes, 2015
Hadronic resonances serve as unique probes in the study of the hot and dense nuclear matter produced in heavy-ion collisions. Properties of the hadronic phase of the collision can be extracted from measurements of the suppression of resonance yields.

Particle production at energies available at the CERN Large Hadron Collider within evolutionary model [PDF]

open access: yes, 2018
The particle yields and particle number ratios in Pb+Pb collisions at the LHC energy $\sqrt{s_{NN}}=2.76$ TeV are described within the integrated hydrokinetic model (iHKM) at the two different equations of state (EoS) for the quark-gluon matter and the ...

Nonperturbative evaluation of quantum particle production in parametric resonance enhanced by noise

open access: yes, 2016
Numerical studies are reported to support the idea to explain the particle production in late inflationary era based on the parametric resonance with a noise effect. Two nonperturbative renormalization group formulations are used to numerically calculate the time evolution of particle numbers.

Search for a pentaquark state decaying into pJ/ψ in Υ(1, 2S) inclusive decays at Belle

open access: yesJournal of High Energy Physics
Using the data samples of 102 million Υ(1S) and 158 million Υ(2S) events collected by the Belle detector, we search for a pentaquark state in the pJ/ψ final state from Υ(1, 2S) inclusive decays.

Search for decays of the 125 GeV Higgs boson into a Z boson and a ρ or ϕ meson

open access: yesJournal of High Energy Physics, 2020
Decays of the 125 GeV Higgs boson into a Z boson and a ρ0(770) or ϕ(1020) meson are searched for using proton-proton collision data collected by the CMS experiment at the LHC at s $$ \sqrt{s} $$ = 13 TeV.
