Measurement of the energy dependence of the e + e − → B B ¯ $$ B\overline{B} $$ , B B ¯ ∗ $$ B{\overline{B}}^{\ast } $$ and B ∗ B ¯ ∗ $$ {B}^{\ast }{\overline{B}}^{\ast } $$ exclusive cross sections

open access: yesJournal of High Energy Physics, 2021
We report the first measurement of the exclusive cross sections e + e − → B B ¯ $$ B\overline{B} $$ , e + e − → B B ¯ ∗ $$ B{\overline{B}}^{\ast } $$ , and e + e − → B ∗ B ¯ ∗ $$ {B}^{\ast }{\overline{B}}^{\ast } $$ in the energy range from 10.63 GeV to ...

Parametric Resonance in a Vibrating Cavity

open access: yes, 2003
We present the study of parametric resonance in a one-dimensional cavity based on the analysis of classical optical paths. The recursive formulas for field energy are given. We separate the mechanism of particle production and the resonance amplification

Effect of the Generalized Uncertainty Principle on Post-Inflation Preheating [PDF]

open access: yes, 2011
We examine effects of the Generalized Uncertainty Principle, predicted by various theories of quantum gravity to replace the Heisenberg's uncertainty principle near the Planck scale, on post inflation preheating in cosmology, and show that it can predict

Calculation of Particle Production by Nambu Goldstone Bosons with Application to Inflation Reheating and Baryogenesis

open access: yes, 1994
A semiclassical calculation of particle production by a scalar field in a potential is performed. We focus on the particular case of production of fermions by a Nambu-Goldstone boson $\theta$.

Monte-Carlo simulations of photohadronic processes in astrophysics [PDF]

open access: yes, 1999
A new Monte Carlo program for photohadronic interactions of relativistic nucleons with an ambient photon radiation field is presented. The event generator is designed to fulfil typical astrophysical requirements, but can also be used for radiation and ...

Parametric resonance in the early Universe—a fitting analysis [PDF]

open access: yes, 2016
Particle production via parametric resonance in the early Universe, is a non-perturbative, non-linear and out-of-equilibrium phenomenon. Although it is a well studied topic, whenever a new scenario exhibits parametric resonance, a full re-analysis is ...
