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 $\phi$

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 ...

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 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

Tachyonic and parametric resonances for massive particle production in an intense scalar plane wave background

open access: yesPhysical Review D
We investigate the stability of an intensive plane wave of a massless or light scalar field ϕ in a trilinear scalar model gϕχ2 due to the resonant production of massive χ particles in a perturbatively forbidden regime. We apply two methods. First, we solve the Heisenberg equation for the quantum amplitudes of the field χ in an external plane wave ...

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.

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 ...
