Production of light (anti)nuclei in pp collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
Understanding the production mechanism of light (anti)nuclei is one of the key challenges of nuclear physics and has important consequences for astrophysics, since it provides an input for indirect dark-matter searches in space. In this paper, the latest

SMEFT probes in future precision DIS experiments [PDF]

open access: yesPhysical Review D, 2023
We analyze the potential of future high-energy deep-inelastic scattering (DIS) experiments to probe new physics within the framework of the Standard Model Effective Field Theory (SMEFT).

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking

open access: yesJournal of High Energy Physics, 2020
The factor of four increase in the LHC luminosity, from 0.5 × 1034 cm −2s −1 to 2.0 × 1034cm −2s −1, and the corresponding increase in pile-up collisions during the 2015–2018 data-taking period, presented a challenge for the ATLAS trigger, particularly ...

First extraction of transversity from data on lepton-hadron scattering and hadronic collisions [PDF]

open access: yesSPIN, 2018
We present the first extraction of the transversity distribution based on the global analysis of pion-pair production in deep-inelastic scattering and in proton-proton collisions with one transversely polarized proton.

Search for dark matter in events with missing transverse momentum and a Higgs boson decaying into two photons in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2021
A search for dark-matter particles in events with large missing transverse momentum and a Higgs boson candidate decaying into two photons is reported. The search uses 139 fb −1 of proton-proton collision data collected at s $$ \sqrt{s} $$ = 13 TeV with ...

Silica Raman scattering probe for absolute calibration of Thomson scattering spectrometers [PDF]

open access: yes, 2021
We have developed a solid state probe for an absolute irradiance calibration of the Thomson scattering system on the Large Plasma Device (LAPD), based on Raman scattering off silica. Measurements performed with a triple-grating spectrometer have investigated the intensities of a pulsed laser beam Raman scattered off crystalline and amorphous silica ...

An event generator for Lepton-Hadron deep inelastic scattering at NLO+PS with POWHEG including mass effects [PDF]

open access: yesJournal of High Energy Physics
We present a generator for lepton nucleon collisions in the DIS regime, focusing in particular on processes with a massive lepton and/or a massive quark in the final state.

Search for direct production of electroweakinos in final states with missing transverse momentum and a Higgs boson decaying into photons in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2020
A search for a chargino-neutralino pair decaying via the 125 GeV Higgs boson into photons is presented. The study is based on the data collected between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb
