“…The production of light neutral mesons in different collision systems is interesting for a variety of reasons: In nucleus-nucleus (AA) collisions the measurements provide important information on the energy loss of partons traversing the Quark-Gluon Plasma (QGP) which is formed in heavy-ion collisions at the LHC. …”

“…We discuss the differences between this new approach and Israel-Stewart theory, emphasizing how such distinctions could affect our current understanding of the hydrodynamic evolution of the quark-gluon plasma. We also explain how to derive this hydrodynamic approach from kinetic theory using a new coarse-graining method that is different from the well-known Chapman-Enskog expansion and the method of moments. …”

“…--HTML-->We present a framework to simulate the dynamics of hard probes such as heavy quarks or jets in a hot, strongly-coupled quark-gluon plasma (QGP) on a quantum computer [1]. Hard probes in the QGP can be treated as open quantum systems governed in the Markovian limit by the Lindblad equation. …”

“…While the transition from hadronic matter to Quark-Gluon Plasma (onset of deconfinement) is now rather uncontroversial, the difficulties in obtaining a unique and quantitative prediction of the QGP signal within the QCD theoretical framework remain and the scientific community still awaits the confirmation of an experimental observation of the critical endpoint of the transition line. …”

“…The correlation between the event-wise average transverse momentum ([𝑝T]) and the harmonic flow (𝑣𝑛) carries important information about the initial-state geometry of the quark-gluon plasma. Additionally, the potential quadrupole deformation in Xe+Xe is predicted to produce an initial state with enhanced shape and size fluctuations, and result in non-trivial change in the correlation. …”

“…Some observables are infrared and collinear safe and thus easily comparable to first-principles calculations, while others offer direct insight into specific physical phenomena such as the quark-gluon plasma formed in heavy-ion collisions. The high-precision capability of the ALICE tracking system allows a unique opportunity at LHC energies to measure tracks with low transverse momentum, permitting high precision access to the softer components inside jets with an excellent angular resolution. …”

“…The main goal of the ALICE experiment is to study the physics of strongly interacting matter, including the properties of the quark-gluon plasma (QGP). The relative production of strange hadrons with respect to non-strange hadrons in heavy-ion collisions was historically considered as one of the signatures of QGP formation. …”

“…The production of a top quark-antiquark pair in association with a Higgs pair (ttHH) plays a special role in this context because, even if much rarer than the gluon fusion or Vector boson fusion production modes, is very sensitive to new physics effects and has implications both on the top and on the Higgs sectors. …”
