    Publicado 2017
    “…The interplay of such fields with QCD anomalies in the Quark--Gluon Plasma (QGP) has been predicted to lead to a number of interesting phenomena, such as the Chiral Magnetic Effect (CME). …”

    “…Charmonium states, such as the J/$\psi$ and $\psi$(2S) mesons, are excellent probes of the deconfined state of matter, the Quark-Gluon Plasma (QGP) created in heavy ion collisions. …”

    Publicado 2017
    “…Strangeness enhancement in AA collisions with respect to pp and pA collisions has long been considered as one of the signatures for quark-gluon plasma (QGP) formation. Recent observations of collective effects in high-multiplicity pp and pA collisions raise the question of whether QGP can also be formed in the smaller systems. …”

    “…A search for the associated production of a standard model Higgs boson with a top quark-antiquark pair ($\mathrm{t\bar{t}H}$) in proton-proton collisions at a center-of-mass energy $\sqrt{s}=13~\mathrm{TeV}$ is presented. …”

    “…In this search two decay modes of the top squark are considered: a four-body decay into a b quark, two additional fermions, and an LSP, and a decay via an intermediate chargino. …”

    Publicado 2018
    “…However, a comprehensive description of the production and polarisation of the $J/\psi$ state at Tevatron and LHC in the complete $p_T$ and rapidity range remains a challenge. The heavy quark spin symmetry yields direct links between the long distance matrix elements describing hadroproduction of different charmonium states. …”

    Publicado 2018
    “…Because photons do not carry color charge, they are unaffected by the medium, and thus provide information about the momentum, direction, and flavor (quark or gluon) of the associated hard-scattered parton before it begins to shower and become quenched. …”

    Publicado 1994
    “…Using the {\it hybrid} moments-Laplace sum rule (HSR), which is well-defined for M_b \rar \infty, in contrast with the popular double Borel (Laplace) sum rule (DLSR), which blows up in this limit when applied to the heavy-to-light processes, we show that the form factor of the B \rar K^* \ \gamma radiative transition is dominated by the light-quark condensate for M_b \rar \infty and behaves like \sqrt M_b. …”

    Publicado 2018
    “…The cross sections of Higgs boson production through gluon--gluon fusion, vector-boson fusion, and in association with a vector boson or a top-quark pair are measured. Measurements of the Higgs boson production divided further into kinematic regions, called simplified template cross sections, are also reported. …”

    “…The high collision energy combined with the large luminosity and clean environment of the e$^+$e$^-$ collisions enables the measurement of the properties of Standard Model particles, such as the Higgs boson and the top quark, with unparalleled precision. CLIC might also discover indirect effects of very heavy new physics by probing the parameters of the Standard Model Effective Field Theory with an unprecedented level of precision. …”

    “…LHCb is one of the experiments collecting data at the Large Hadron Collider (LHC), and it is the only one specifically designed to perform measurements in the bottom and charm quark sector. Most of the results obtained by LHCb in these sectors during the first two runs of the LHC are the best currently available, and much larger data samples are expected from upcoming runs. …”
