Measurement of the inclusive production of neutral pions and charged particles on the Z0 resonance [PDF]

Physics Letters B, 1991
Abstract We present a study of the inclusive production of neutral pions and charged particles from 112 000 hadronic Z 0 decays. The measured inclusive momentum distributions can be reproduced by parton shower Monte Carlo programs and also by an analytical QCD calculation.

Probing Planckian physics: resonant production of particles during inflation and features in the primordial power spectrum [PDF]

Physical Review D, 1999
The phenomenon of resonant production of particles {\it after} inflation has received much attention in the past few years. In a new application of resonant production of particles, we consider the effect of a resonance {\em during} inflation.

Particles Production in Neutron Stars by Means of the Parametric Resonance Mechanism

, 2008
Using a Lagrangean toy model the coupling of a negative pion superconducting field and the electromagnetic field of the star is analyzed. A numerical study of particles produced in the neutron star medium by means of the well-known parametric resonance phenomenon is performed.

Search for heavy resonances decaying to ZZ or ZW and axion-like particles mediating nonresonant ZZ or ZH production at $$ \sqrt{s} $$ = 13 TeV [PDF]

Journal of High Energy Physics, 2022
Abstract A search has been performed for heavy resonances decaying to ZZ or ZW and for axion-like particles (ALPs) mediating nonresonant ZZ or ZH production, in final states with two charged leptons (ℓ = e, μ) produced by the decay of a Z boson, and two quarks produced by the decay of a Z, W, or Higgs boson H.

The production of high-momentum particles and resonances in pp collisions at the CERN intersecting storage rings [PDF]

Nuclear Physics B, 1983
Data are reported on the momentum distributions of Λ, Λ (1520), φ (1020), Λ and p, inclusively produced between 1° and 2° with respect to one of the primary proton beams at the CERN Intersecting Storage Rings. In addition, the decay angular distribution of the Λ(1520), the ratio of the cross sections for the production of Σ− (1385) and Σ+ (1385) and ...

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

, 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.

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

We investigate the stability of an intensive plane wave of a massless or light field $ϕ$ in a trilinear scalar model $gϕχ^2$ 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 ...
