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 ...
Topic model for four-top at the LHC
(Springer, 2020-01)
We study the implementation of a Topic Model algorithm in four-top searches at the LHC as a test-probe of a not ideal system for applying this technique. We study this Topic Model behavior as its different hypotheses such ...
Deep inelastic scattering structure functions of holographic spin-1 hadrons with N f ≥ 1
(Springer, 2014-01)
Two-point current correlation functions of the large N limit of supersymmetric and non-supersymmetric Yang-Mills theories at strong coupling are investigated in terms of their string theory dual models with quenched flavors. ...
Semi-inclusive deep-inelastic scattering, parton distributions, and fragmentation functions at a future electron-ion collider
(American Physical Society, 2019-05-07)
We present a quantitative assessment of the impact a future electron-ion collider would have in the determination of parton distribution functions in the proton and parton-to-hadron fragmentation functions through ...
Deep inelastic scattering from polarized spin-1/2 hadrons at low x from string theory
(Springer, 2018-10)
We study polarized deep inelastic scattering of charged leptons from spin-1/2 hadrons at low values of the Bjorken parameter and large ?t Hooft coupling in terms of the gauge/string theory duality. We calculate the structure ...
Soft-gluon resummation for high-pT inclusive-hadron production at COMPASS
(American Physical Society, 2013-07-01)
We study the cross section for the photoproduction reaction N ! hX in fixed-target scattering at COMPASS, where the hadron h is produced at large transverse momentum. We investigate the role played by higher-order QCD ...
Through the looking-glass with ALICE into the quark-gluon plasma: A new test for hadronic interaction models used in air shower simulations
(Elsevier Science, 2020-11)
Recently, the ALICE Collaboration reported an enhancement of the yield ratio of strange and multi-strange hadrons to charged pions as a function of multiplicity at mid-rapidity in proton-proton, proton-lead, lead-lead, and ...
Search for new resonances in mass distributions of jet pairs using 139 fb−1 of pp collisions at s√ s = 13 TeV with the ATLAS detector
(Springer, 2020-03-25)
A search for new resonances decaying into a pair of jets is reported using the dataset of proton-proton collisions recorded at √s = 13 TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, ...
