The ALICE experiment is dedicated to studying the properties of the quark-gluon plasma, a strongly-interacting matter produced in collisions of heavy-ions at the LHC. In this talk, recent highlights from ALICE in Pb+Pb collisions investigating the properties of the QGP will be shown, along with results from p+p and p+Pb collisions. Recently, ALICE has undergone a major upgrade in preparation...

The LHCb detector is a unique tool for studying heavy-ion collisions at the LHC. Because of its forward acceptance, the LHCb detector is able to study heavy ion collisions in kinematic regions complementary to those probed at other LHC and RHIC experiments. Furthermore, the LHCb detector's excellent momentum and vertex resolution make it an ideal tool for studying heavy-flavor production. In...

The Solenoidal Tracker at RHIC (STAR) experiment is dedicated to the study of the different phases and properties of high energy-density QCD matter produced in ion-ion collisions at RHIC. A major current focus is centered on mapping the QCD phase diagram, elucidating the transport and anomalous transport properties of the Quark-Gluon Plasma (QGP), and testing for chiral symmetry restoration. ...

The PHENIX result at the Relativistic Heavy Ion Collider has collected data scanning system sizes from pp and $^3$HeAl to Au+Au and U+U at collision energies from $\sqrt{s_{NN}}=7.7-510$ GeV. The extensive measurements from these data improve our understanding of the Quark Gluon Plasma and the origin of the proton spin. PHENIX's measurements of $\pi^0$ mesons, photons, heavy flavor...

In ultra-relativistic heavy-ion collisions a hot and dense QCD matter, called Quark- Gluon Plasma (QGP), is produced. Heavy quarks (charm and beauty) are powerful probes to investigate the production and properties of the QGP. They are produced in hard scattering processes with large momentum transfer before the formation of the QGP, thus experiencing the full evolution of the system. The...

The recent observations of enhanced particle yields, including 𝐽/𝜓, in high event multiplicity 𝑝+𝑝 collisions at RHIC and LHC suggest possible strong contributions from semi-hard Multi-Parton Interactions (MPI) as well as other final state interactions. These new results challenge not only the traditional “single hard-scattering” pQCD description that is widely used in calculating particle...

Quarkonia are considered as excellent probes to understand the properties of the quark gluon plasma (QGP), which is expected to be created in heavy ion collisions. In particular, experimental results of azimuthal anisotropy for charmonium states are expected to provide crucial information on the dynamics of quarkonia as well as the QGP properties. In this presentation, we present a detailed...

Heavy-ion collisions at the LHC and RHIC create a large enough energy density to form a deconfined medium of strongly-interacting quarks and gluons called quark-gluon plasma (QGP). The properties of the QGP including its near-perfect hydrodynamic behavior arising from the interactions between elementary quarks and gluons are not very well understood. Jets have proven to be crucial probes of...

High energy partons lose energy when traversing the hot and dense medium produced in heavy-ion collisions. This results in a modification of the transverse momentum distribution of jets manifesting a phenomenon known as jet quenching. Early measurements have established in heavy ion collisions that jet quenching results in significant modifications to the transverse momentum balance of dijet...

Hard partonic scatterings serve as an important probe of quark-gluon-plasma (QGP) properties. The properties of jets and their constituents can provide a tool for understanding the partonic energy loss mechanisms. Low momentum jets offer a unique window into partonic energy loss because they reconstruct the partons which have lost a significant amount of energy to the QGP medium. The main...

Dileptons are a crucial probe of the strongly interacting matter created in ultra-relativistic heavy-ion collisions. Leptons are produced during the whole evolution of the created matter and can traverse the medium with minimal interactions. Different kinematics of dilepton pairs (mass and transverse momentum ranges) can selectively probe the properties of the formed matter throughout its...

QCD phase structure under magnetic field is a hot issue. On the hardonic side, Skyrme model with gauged Wess-Zumino Witten term is one of the simple low energy effective theory featuring chiral anomaly. Within such framework we investigate how an external magnetic field deforms the Skyrmion while preserving the homotopy. The Skyrme crystal constituted by multiple such magnetized Skyrmions...

The quark gluon plasma (QGP) created in the Ultrarelativistic heavy-ion collisions behaves like a near perfect fluid with a small specific shear viscosity. Due to its transience and microscopic size, the QGP cannot be observed directly, but only through the particles it emits.

The creation of a Quark-Gluon Plasma (QGP) during heavy-ion collisions constitute a unique opportunity to study strong interactions under extreme conditions. Therefore, the JETSCAPE collaboration was started with the purpose of developing a multistage framework capable of combining different models at each stage, in order to study the evolution of jets and high-pT probes during heavy-ion...

How collectivity originates and evolves in the collisions of small size systems is a highly debated topic in the heavy ion community. The evolution may be associated with both hydrodynamic and non-hydrodynamic modes. Furthermore, the uncertaities of initial geometry due to the internal nucleonic structure and its fluctuations will significantly degrade the predictive power of the available...

At LHC energies, the measurements involves light quark hadrons, strange, charm and bottom hadrons in pp, pPb, and ultra-peripheral PbPb and pPb collisions.

Quantum Chromodynamics allows for the formation of parity-odd domains inside the medium produced in heavy-ion collisions associated with a net chirality of the quarks. Thus one local $CP$ violation phenomenal, Chiral Magnetic Effect (CME), is allowed in the heavy-ion collisions. In the past two decades, many experimental researchers are looking for such an effect with different observables and...
