    “…Studies of the fragmentation of jets into charged particles in heavy-ion collisions can help in understanding the mechanism of jet quenching by the hot and dense QCD matter created in such collisions, the quark-gluon plasma. This note presents a measurement of the angular distribution of charged particles around the jet axis in $\sqrt{s_{\mathrm{NN}}}=$ 5.02 TeV Pb+Pb and $pp$ collisions, done using the ATLAS detector at the LHC. …”

    “…Motivated by a semi-holographic approach to the dynamics of quark-gluon plasma which combines holographic and perturbative descriptions of a strongly coupled infrared and a more weakly coupled ultraviolet sector, we construct a hybrid two-fluid model where interactions between its two sectors are encoded by their effective metric backgrounds, which are determined mutually by their energy-momentum tensors. …”

    “…The recent status of hard thermal photon production in relativistic heavy ion collisions is reviewed and the current rates are presented with emphasis on corrected bremsstrahlung processes in the quark-gluon plasma (QGP) and quark-hadron duality. Employing Bjorken hydrodynamics with an EOS supporting the phase transition from QGP to hot hadron gas (HHG), thermal photon spectra are computed. …”

    “…The exclusion ranges from 13.0~pb at 150~GeV to 7.0~fb at 1~TeV for Higgs boson production in association with b-quarks and from 23.6~pb at 150~GeV to 7.5~fb at 1~TeV for Higgs bosons produced via gluon-gluon fusion. The obtained exclusion limit on $\sigma(pp\to\phi)\times\text{BR}(\phi\to\tau\tau)$ can be related to an exclusion of the MSSM parameter space in the $M_A$-$\tan\beta$-plane. …”
