    “…The flow results allow to improve the understanding of initial conditions of nuclear collisions, hydrodynamical behaviour of quark-gluon plasma (QGP) and parton energy loss. The dynamic properties of the QGP can also be studied using a modified Pearson's correlation coefficient, $\rho(v_n,p_\mathrm{T})$, that quantifies correlation between the mean transverse momentum and the magnitude of the flow vector. …”

    “…In order to probe the coupling of the Higgs boson to the fermions and vector bosons, the inclusive cross sections times the branching ratio of the Higgs boson to two photons are measured for four primary production modes: gluon-gluon fusion ($ggF$), vector boson fusion ($VBF$), vector boson associated production ($VH$), and top quark associated production ($t\bar{t}H$). …”

    “…The model dependence of the constraints is studied by successively allowing for new physics contributions to the couplings of the Higgs boson to massive vector bosons, to photons, and to gluons. In the most general case, we find that the current data still permits a significant $ \mathcal{CP} $-odd component in the top-Yukawa coupling. …”
