    Publicado 2018
    “…These results show a weaker collective flow associated with charm quarks than with light flavor quarks in high-multiplicity pPb collisions, and may indicate a weaker coupling between heavy quarks and the hypothesised hydrodynamic quark-gluon plasma.…”

    “…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. …”

    “…The azimuthal anisotropies of particle yields observed in relativistic heavy-ion collisions have been traditionally considered as a strong evidence of the formation of a de-confined quark-gluon plasma produced in these collisions. However multiple recent measurements from the LHC experiments in $pp$ and $p$+Pb systems show similar features as those observed in Pb+Pb collisions, indicating the possibility of the production of such a de-confined medium also in smaller collision systems. …”

    “…The decay of the W boson pair is reconstructed in the $\ell \nu \ell ' \nu '$ and $\ell \nu q\bar{q}$ final states. Both gluon fusion and vector boson fusion production of the signal are considered, with a number of hypotheses for their relative contribution investigated. …”

    “…Many models of dark matter feature a new particle that mediates the interaction between Standard Model particles and dark matter; this mediator particle could decay to quarks and gluons, producing a dijet resonance signature in the detector. …”

    “…The $I_\mathrm{AA}$ is observed to be significantly suppressed at large hadron $p_\mathrm{T}$ or $x_\mathrm{hZ}$, presumably due to interaction of the hard-scattered partons with a hot and dense quark-gluon plasma. The $I_\mathrm{AA}$ results are compared to the predictions of jet modification in several Monte Carlo generators and theoretical calculations.…”

    “…In heavy-ion collisions, the long-range correlations are known to arise from the collective dynamics of the produced quark-gluon plasma (QGP). The similarity between the $pp$ and heavy-ion measurements raises the possibility that a tiny droplet of the QGP is produced even in $pp$ collisions. …”

    “…It has been recently suggested that the exclusive $J/\psi$ production of electron-deuteron scattering at the Electron-Ion Collider (EIC) would provide new insights into the SRCs, in particular from the aspect of the underlying quark-gluon dynamics. In the absence of electron-nucleus data from an EIC, data from deuteron-gold (d+Au) ultra-peripheral collisions (UPCs) recorded by the STAR detector at the Relativistic Heavy Ion Collider can be used as a proxy to test various techniques and hypotheses. …”
