Learning the latent structure of collider events
(Springer, 2020-10)
We describe a technique to learn the underlying structure of collider events directly from the data, without having a particular theoretical model in mind. It allows to infer aspects of the theoretical model that may have ...
Absorptive one-loop corrections and the complex-mass prescription for the Δ resonance propagator
(IOP Publishing, 2012-07)
It is shown that the absorptive one-loop self-energy corrections to the δ ++ propagator can reproduce the complex-mass prescription for its resonant form. The effects of absorptive corrections beyond the ones considered ...
Search for heavy particles decaying into a top-quark pair in the fully hadronic final state in pp collisions at s√= 13 TeV with the ATLAS detector
(American Physical Society, 2019-02)
A search for new particles decaying into a pair of top quarks is performed using proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at a center-of-mass energy of s=13 TeV corresponding ...
Search for invisible particles produced in association with single-top-quarks in proton-proton collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector
(Springer, 2015-02)
A search for the production of single-top-quarks in association with missing energy is performed in proton?proton collisions at a centre-of-mass energy of s√=8 TeV with the ATLAS experiment at the large hadron collider ...
Self-interacting dark matter in cosmology: Accurate numerical implementation and observational constraints
(IOP Publishing, 2021-10)
This paper presents a systematic and accurate treatment of the evolution of cosmological perturbations in self-interacting dark matter models, for particles which decoupled from the primordial plasma while relativistic. ...
Constraining R-axion models through dijet searches at the LHC
(Elsevier Science, 2019-02-10)
The search at hadron colliders for new massive resonances of a few 100 GeVs that couple effectively to colored states is an extremely challenging issue, due principally to the presence of large QCD multijet backgrounds at ...
Search for low-mass dijet resonances using trigger-level jets with the ATLAS detector in pp collisions at s√=13 TeV
(American Physical Society, 2018-04)
Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-jet triggers, whose data-collection rates ...
Search for t-t resonances in the lepton plus jets final state with ATLAS using 4.7 fb-1 of pp collisions at √s=7 TeV
(American Physical Society, 2013-07)
A search for new particles that decay into top quark pairs ( t ¯ t ) is performed with the ATLAS experiment at the LHC using an integrated luminosity of 4.7 fb-1of proton–proton (pp) collision data collected at a center-of-mass ...
Search for light resonances decaying to boosted quark pairs and produced in association with a photon or a jet in proton-proton collisions at s√=13 TeV with the ATLAS detector
(American Physical Society, 2018-01)
This Letter presents a search for new light resonances decaying to pairs of quarks and produced in association with a high-pT photon or jet. The dataset consists of proton-proton collisions with an integrated luminosity ...
Differential and total cross sections of non-capture breakup reactions in the 6Li+ 144Sm system
(American Physical Society, 2014-01)
The breakup of the projectile-like fragments in reactions induced by 6Li beams on a 144Sm target at energies close to the Coulomb barrier has been measured through the coincident detection of the emitted light particles. ...
