We present, in the framework of interacting hadron resonance gas, an evaluation thermodynamical quantities. The interaction is modelled via a correction for finite size hadrons. investigate sensitivity model calculations on radius hadrons, which parameter model. Our quantities as energy and entropy densities pressure are confronted with predictions using lattice Quantum Chromodynamics (QCD) formalism.
The future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented. Four major scientific goals identified: characterisation of macroscopic long wavelength Quark-Gluon Plasma (QGP) properties unprecedented precision, investigation microscopic parton dynamics underlying QGP properties, development a unified picture particle production from small (pp) to large (nucleus--nucleus) systems, exploration densities in nuclei broad ($x$, $Q^2$) kinematic range...
The production of dileptons with an invariant mass in the range 1 GeV < M 5 provides unique insight into approach to thermal equilibrium ultrarelativistic nucleus-nucleus collisions. In this range, they are produced through annihilation quark-antiquark pairs early stages collision. They sensitive anisotropy quark momentum distribution, and also abundance, which is expected be underpopulated relative equilibrium. We take account both effects based on recent theoretical developments QCD...
We propose the angular distribution of lepton pairs produced in ultrarelativistic heavy-ion collisions as a probe thermalization quark-gluon plasma. focus on dileptons with invariant masses large enough that they are through quark--antiquark annihilation early stages collision. The rest frame pair then reflects quark momenta. At times, transverse pressure plasma is larger than its longitudinal result fast expansion, which results an oblate distribution. By contrast, direct (Drell-Yan)...
The calibration and performance of the LHCb Calorimeter system in Run 1 2 at LHC are described. After a brief description sub-detectors their role trigger, methods used for each part reviewed. changes which occurred with increase beam energy explained. performances calorimetry $\gamma$ $\pi^0$ detailed. A few results from collisions recorded $\sqrt {s}$ = 7, 8 13 TeV shown.
Exclusive heavy-vector meson photoproduction is a prominent signal in collider experiments with hadron beams. At the highest photon-hadron collision energies, this process considered as candidate to constrain gluon parton distribution function (PDF) at small longitudinal momentum fractions. However, framework of collinear factorization, exclusive particle production described terms generalized distributions (GPDs). In contribution, we investigate connection between GPDs and PDFs leading...
Hadron production in relativistic nuclear collisions is well described the framework of Statistical Hadronization Model (SHM). We investigate influence on SHM predictions hadron mass spectra for light-flavor baryons and mesons modified by addition about 500 new states as predicted lattice QCD a quark model. The deterioration resulting thermodynamic fit quality obtained Pb–Pb collision data at sNN=2.76 TeV suggests that additional are not suited to be naively used since also interactions...

Quark-Gluon Plasma (QGP), a QCD state of matter created in ultra-relativistic heavy-ion collisions, has remarkable properties, including, for example, low shear viscosity over entropy ratio. By detecting the collection low-momentum particles that arise from collision, it is possible to gain quantitative insight into matter. However, its fast evolution and thermalization properties remain elusive. Only using high momentum objects as probes QGP can unveil constituents at different wavelengths....

The LHCb experiment offers the unique opportunity to study heavy-ion interactions in forward region (2 <eta< 5), a kinematic domain complementary other 3 large experiments at LHC. detector has excellent capabilities for reconstructing quarkonia and open charm states, including baryons, down zero $p_T$. It can separate prompt displaced components. In $p$Pb collisions, both backward rapidities are covered thanks possibility of beam reversal. Results include measurements nuclear modification...
