    “…The signal models explored here are Vector-Like Quark $B$, $T$, and $T_{5/3}$ via pair production, and several 4-top ($t\overline{t}t\overline{t}$) signatures: Standard Model production, contact interaction, and a model with two Universal Extra Dimension under the real projective plane geometry.…”

    “…This poster presents the measurement of the inclusive top-quark pair-production cross-section in the lepton+jets channel with 20.2 fb$^{-1}$ of 8 TeV data using a neural-network discriminant and the reconstructed mass of the hadronically decaying $W$ boson. …”

    “…The process being searched for, unlike other Higgs processes (e.g. ttH->γγ), is sensitive to the sign of Yukawa coupling between top-quark and Higgs-boson. However, tH-production has a very small cross section in SM, which complicates the searches. …”

    Publicado 2017
    “…Measurements of jets and particle correlations in nucleus-nucleus collisions are intended to probe QCD interactions in the high temperature phase, where matter is understood to behave as a quark-gluon plasma. Two probes are reviewed: jets which are used to study the energy loss of hard-scattered partons in this medium and particle correlations which are used to understand collective effects of the bulk matter. …”

    Publicado 2018
    “…Production of heavy flavoured hadrons can serve as a probe of QCD processes and, in the case of production in heavy ion collisions, also as a probe of the properties of deconfined quark-gluon plasma. This paper describes the latest results in the production of charmonium in the ATLAS experiment at the Large Hadron Collider. …”

    “…The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on a combined analysis of proton-proton collision data at center-of-mass energies of $\sqrt{s}=7$, 8 and 13 TeV, corresponding to integrated luminosities of up to 5.1, 19.7, and 35.9 fb${}^{-1}$, respectively. …”

    “…Promptly produced quarkonia are directly affected by the interaction with the hot nuclear matter, while non-prompt production allows for the study of $b$-quark energy loss. The studies of quarkonia production are complemented by measurements of the azimuthal modulation of $J/\psi$ production. …”

    “…Many theories beyond the Standard Model (BSM) have been proposed to address several of the Standard Model shortcomings, such as the origin of dark matter and neutrino masses, the fine-tuning of the Higgs boson mass, or the observed pattern of masses and mixing angles in the quark and lepton sectors. Many of these BSM extensions predict new particles or interactions directly accessible at the LHC. …”

    “…Recent results in high-multiplicity pp collisions show features similar to those that are associated with the formation of a quark$-$gluon plasma in heavy-ion collisions. Investigating the modification of the intra-jet properties as a function of event multiplicity in pp collisions can provide deeper insight into the nature of these effects. …”
