Post-inflationary preheating with weak coupling [PDF]

open access: yes, 2014
Particle production in the background of an external classical oscillating field is a key process describing the stage of preheating after inflation.

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 ...

Constraints on resonant particle production during inflation from the matter and CMB power spectra

open access: yesPhysical Review D, 2004
We analyze the limits on resonant particle production during inflation based upon the power spectrum of fluctuations in matter and the cosmic microwave background. We show that such a model is consistent with features observed in the matter power spectrum deduced from galaxy surveys and damped Lyman-alpha systems at high redshift.

Search for heavy resonances in final states with four leptons and missing transverse momentum or jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for a new heavy boson produced via gluon-fusion in the four-lepton channel with missing transverse momentum or jets is performed. The search uses proton-proton collision data equivalent to an integrated luminosity of 139 fb −1 at a centre-of ...

Observation of the decay ψ(3686) → Σ − Σ ¯ + $$ {\Sigma}^{-}{\overline{\Sigma}}^{+} $$ and measurement of its angular distribution

open access: yesJournal of High Energy Physics, 2022
Using (448.1 ± 2.9) × 106 ψ(3686) events collected with the BESIII detector at the BEPCII collider, the decay ψ(3686) → Σ − Σ ¯ + $$ {\Sigma}^{-}{\overline{\Sigma}}^{+} $$ is observed for the first time with a branching fraction of (2.82 ± 0.04stat.

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 ...

Preheating after multifield inflation with nonminimal couplings. II. Resonance structure [PDF]

open access: yes, 2016
This is the second in a series of papers on preheating in inflationary models comprised of multiple scalar fields coupled nonminimally to gravity. In this paper, we work in the rigid-spacetime approximation and consider field trajectories within the ...

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions

open access: yesFEBS Letters, EarlyView.
This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...

Search for boosted low-mass resonances decaying into hadrons produced in association with a photon in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
Many extensions of the Standard Model, including those with dark matter particles, propose new mediator particles that decay into hadrons. This paper presents a search for such low mass narrow resonances decaying into hadrons using 140 fb −1 of proton ...
