“…One major achievement in HIC was the discovery that QCD matter at energy densities greater than 1 GeV=fm 3 acts like a strongly interacting plasma of quarks and gluons. Indeed, the fast (local) thermalization time and the good agreement of the data at RHIC with ideal relativistic hydrodynamics models (which admit a fluid evolution with zero viscosity) are evidences that the matter formed at RHIC is a strongly interacting plasma of quarks and gluons [1], as confirmed by the Large Hadron Collider (LHC) data [2].…”

“…It corresponds to zero charge (isospin) chemical potential, μ Q ¼ 0, and the strangeness chemical potential is one third of the total baryonic chemical potential, μ S ¼ 1=3μ B . This is the relevant scenario to simulate matter created by 1 For the QCD CEP, the associated soft mode is a linear combination of fluctuations of the chiral condensate and the quark number density instead of pure chiral fluctuations [38]. ultrarelativistic HIC.…”

The location of the critical end point (CEP) and the isentropic trajectories in the QCD phase diagram are investigated. We use the (2 þ 1) Nambu-Jona-Lasinio model with the Polyakov loop coupling for different scenarios, namely by imposing zero strange quark density, which is the case in the ultrarelativistic heavy ion collisions, and β equilibrium. The influence of strong magnetic fields and of the vector interaction on the isentropic trajectories around the CEP is discussed. It is shown that the vector interaction and the magnetic field, having opposite effects on the first-order transition, affect the isentropic trajectories differently: as the vector interaction increases, the first-order transition becomes weaker and the isentropes become smoother; when a strong magnetic field is considered, the first-order transition is strengthened and the isentropes are pushed to higher temperatures. No focusing of isentropes in region towards the CEP is seen.

“…It has also been recognised as a powerful tool to study the fundamental properties of quark-gluon plasma (QGP) created in these collisions [70][71][72][73][74][75][76]. Furthermore, since the nuclear parton distribution functions (nPDFs) [77][78][79][80][81][82] (especially of the gluon) cannot be well determined using the available nuclear deep inelastic scattering (DIS) and Drell-Yan experimental data compared with the PDFs of the free nucleon, the measurements of prompt photon production in heavy-ion collisions can be used to constrain the gluon distributions within nuclei [83][84][85][86].…”

The prompt photon production in hadronic collisions has a long history of providing information on the substructure of hadrons and testing the perturbative techniques of QCD. Some valuable information about the parton densities in the nucleon and nuclei, especially of the gluon, can also be achieved by analysing the measurements of the prompt photon production cross section whether inclusively or in association with heavy quarks or jets. In this work, we present predictions for the inclusive isolated prompt photon production in pp collisions at center-of-mass energy of 13 TeV using various modern PDF sets. The calculations are presented as a function of both photon transverse energy and pseudorapidity for the ATLAS kinematic coverage. We also study in detail the theoretical uncertainty in the cross sections due to the variation of the renormalization, factorization, and fragmentation scales. Moreover, we introduce and calculate the ratios of photon momenta for different rapidity regions and study the impact of various input PDFs on such quantity.

“…Such energy densities are more than one order of magnitude above the critical value, ε crit ≈ 1 GeV/fm 3 , predicted by lattice quantum chromodynamics (QCD) calculations [2] for the formation of a deconfined system of bare-mass quarks and gluons (Quark Gluon Plasma, QGP) [3]. Among all experimental observables, particles with large transverse : Left: Examples of the sensitivity of various perturbative probes to quark-gluon matter properties in A-A collisions [4]. Right: "Jet quenching" event displays in central Pb-Pb collisions at the LHC: monojetlike event [5] (top) and γ-jet event with a recoiling jet with reduced energy [6] (bottom).…”

The main results on electroweak probes, jets, high-p T hadrons, heavy-flavour and quarkonia production from the first two years of heavy-ion operation at the Large Hadron Collider (LHC) are briefly reviewed. Data measured at center-of-mass energies √ s NN = 2.76 TeV in lead-lead (Pb-Pb) collisions are compared to proton-proton (p-p) measurements in order to extract information on the properties of hot and dense strongly-interacting matter.
