Search for periodic signals in the dielectron and diphoton invariant mass spectra using 139 fb −1 of pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for physics beyond the Standard Model inducing periodic signals in the dielectron and diphoton invariant mass spectra is presented using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. Novel

Measurements of differential production cross sections for a Z boson in association with jets in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV

open access: yesJournal of High Energy Physics, 2017
Cross sections for the production of a Z boson in association with jets in proton-proton collisions at a centre-of-mass energy of s = 8 $$ \sqrt{s}=8 $$ TeV are measured using a data sample collected by the CMS experiment at the LHC corresponding to 19.6

Universe Reheating after Inflation

open access: yes, 1994
We study the problem of scalar particle production after inflation by a rapidly oscillating inflaton field. We use the framework of the chaotic inflation scenario with quartic and quadratic inflaton potentials.

Gravitational production of scalar dark matter [PDF]

open access: yes, 2019
We investigate the gravitational production of scalar dark matter particles during the inflationary and reheating epochs. The oscillatory behavior of the curvature scalar R during the reheating phase generates two different enhancement mechanisms in the ...

Coherent photoproduction of ρ 0 vector mesons in ultra-peripheral Pb-Pb collisions at s NN $$ \sqrt{{\mathrm{s}}_{\mathrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics, 2020
Cross sections for the coherent photoproduction of ρ 0 vector mesons in ultra-peripheral Pb-Pb collisions at s NN $$ \sqrt{{\mathrm{s}}_{\mathrm{NN}}} $$ = 5.02 TeV are reported. The measurements, which rely on the π + π − decay channel, are presented in

A search for new resonances in multiple final states with a high transverse momentum Z boson in s $$ \sqrt{s} $$ = 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A generic search for resonances is performed with events containing a Z boson with transverse momentum greater than 100 GeV, decaying into e + e − or μ + μ − . The analysed data collected with the ATLAS detector in proton-proton collisions at a centre-of-

Mode-mixing quantum gates and entanglement without particle creation in periodically accelerated cavities [PDF]

open access: yes, 2013
We show that mode-mixing quantum gates can be produced by non-uniform relativistic acceleration. Periodic motion in cavities exhibits a series of resonant conditions producing entangling quantum gates between different frequency modes.

Measurement of the forward η meson production rate in p-p collisions at s $$ \sqrt{\textrm{s}} $$ = 13 TeV with the LHCf-Arm2 detector

open access: yesJournal of High Energy Physics, 2023
The forward η mesons production has been observed by the Large Hadron Collider forward (LHCf) experiment in proton-proton collision at s $$ \sqrt{s} $$ = 13 TeV. This paper presents the measurement of the inclusive production rate of η in p T < 1.1 GeV/c,

Production of Dark Sector Particles via Resonant Positron Annihilation on Atomic Electrons

open access: yesPhysical Review Letters
Resonant positron annihilation on atomic electrons provides a powerful method to search for light new particles coupled to e+e−. Reliable estimates of production rates require a detailed characterization of electron momentum distributions. We describe a general method that harnesses the target material Compton profile to properly include electron ...

Analyzing Subvisible Particles in Protein Drug Products: a Comparison of Dynamic Light Scattering (DLS) and Resonant Mass Measurement (RMM) [PDF]

open access: yesThe AAPS Journal, 2014
Aggregation is common in protein drug manufacture, and while the effects of protein particulates are under investigation, many techniques applicable for their characterization have been recently developed. Among the methods available to characterize and quantify protein aggregates, none is applicable over the full size range and different methods often
