Cross section measurements of the e + e − → D *+ D *− and e + e − → D *+ D − processes at center-of-mass energies from 4.085 to 4.600 GeV

open access: yesJournal of High Energy Physics, 2022
The Born cross sections of the e + e − → D *+ D *− and e + e − → D *+ D − processes are measured using e + e − collision data collected with the BESIII experiment at center-of-mass energies from 4.085 to 4.600 GeV, corresponding to an integrated ...

Final state interaction in the production of heavy unstable particles

open access: yes, 1996
We make an attempt to discuss in detail the effects originating from the final state interaction in the processes involving production of unstable elementary particles and their subsequent decay.

Reheating in the Presence of Inhomogeneous Noise [PDF]

open access: yes, 1999
Explosive particle production due to parametric resonance is a crucial feature of reheating in an inflationary cosmology. Coherent oscillations of the inflaton field lead to a periodically varying mass in the evolution equation of matter and ...

Measurement of the e + e − → K S 0 K L 0 $$ {K}_S^0{K}_L^0 $$ π 0 cross sections from s $$ \sqrt{s} $$ = 2.000 to 3.080 GeV

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

Axion-like particle searches at DarkQuest

open access: yesJournal of High Energy Physics, 2022
Axion-like particles (ALPs) interacting with the Standard Model can be abundantly produced in proton beam fixed-target experiments. Looking for their displaced decays is therefore an effective search strategy for ALPs with a mass in the MeV to GeV range.

Patterns from preheating [PDF]

open access: yes, 1998
The formation of regular patterns is a well-known phenomenon in condensed matter physics. Systems that exhibit pattern formation are typically driven and dissipative with pattern formation occurring in the weakly non-linear regime and sometimes even in ...

Weak Production of Strange Particles and $\eta$ Mesons off the Nucleon

open access: yes, 2015
The strange particle production induced by (anti)neutrino off nucleon has been studied for $|\Delta S|=0$ and $|\Delta S|=1$ channels. The reactions those we have considered are for the production of single kaon/antikaon, eta and associated particle ...

Light neutral-meson production in pp collisions at $$\sqrt{\text{s}}$$ = 13 TeV

open access: yesJournal of High Energy Physics
The momentum-differential invariant cross sections of π 0 and η mesons are reported for pp collisions at $$\sqrt{s}$$ = 13 TeV at midrapidity (|y| < 0.8). The measurement is performed in a broad transverse-momentum range of 0.2 < p T < 200 GeV/c and 0.4 <

Resonance Production in RHIC Collisions

open access: yes, 2006
Results of resonance particle production measured at RHIC in $\sqrt{s_{\rm NN}} = $ 200 GeV Au+Au collisions are compared to measurements in p+p and d+Au collisions in order to verify the existence of an extended hardronically interacting medium.
