Library of Simulated Gamma-Ray Glows and Application to Previous Airborne Observations
(Journal article; Peer reviewed, 2023)Gamma-Ray Glows (GRGs) are high energy radiation originating from thunderclouds, in the MeV energy regime, with typical duration of seconds to minutes, and sources extended over several to tens of square kilometers. GRGs ... -
Light (anti-)nuclei production and elliptic flow at the LHC with ALICE
(Peer reviewed; Journal article, 2019)Results on the production of stable light nuclei, including deuterons, 3He, 4He and the corresponding anti-nuclei, in Pb–Pb collisions at √sNN = 2.76 TeV and √sNN = 5.02 TeV are presented and compared with theoretical ... -
Light absorption and scattering of 40–170 nm gold nanoparticles on glass substrates
(Peer reviewed; Journal article, 2017)The localized surface plasmon resonance (LSPR) effect in metal nanoparticles is important for many applications ranging from detectors and sensors to photovoltaic devices. The LSPR wavelength is sensitive to the shape, ... -
Light meson spectroscopy from Dalitz plot analyses of ηc decays to η0 K+K− , η0 π + π − , and ηπ + π − produced in two-photon interactions
(Journal article; Peer reviewed, 2021)We study the processes γγ→ηc→η′K+K−, η′π+π−, and ηπ+π− using a data sample of 519 fb−1 recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy e+e− collider at center-of-mass energies at and near ... -
Light neutral meson production in heavy ion collisions with ALICE in the era of precision physics at the LHC
(Journal article; Peer reviewed, 2021)The production of light neutral mesons in AA collisions probes the physics of the Quark-Gluon Plasma (QGP), which is formed in heavy-ion collisions at the LHC. More specifically, the centrality dependent neutral meson ... -
Light scalars in the Weinberg 3HDM potential with spontaneous CP violation
(Journal article; Peer reviewed, 2022)The Z2×Z2-symmetric 3HDM potential, sometimes called Weinberg's 3HDM potential, can accommodate both explicit and spontaneous CP violation as well as natural flavour conservation and is hence relevant for studies of CP ... -
Light-quark and gluon jet discrimination in pp collisions at √s = 7 TeV with the ATLAS detector
(Peer reviewed; Journal article, 2014-08-21)A likelihood-based discriminant for the identification of quark- and gluon-initiated jets is built and validated using 4.7 fb−1 of proton–proton collision data at √s = 7 TeV collected with the ATLAS detector at the LHC. ... -
