We are proposing an experiment to study $\phi$ mass modification through $K^{+}K^{-}$ decay in p+A collisions at J-PARC. We exect to obtain several hundred thousands of $\phi \rightarrow K^{+}K^{-}$ decays in p+C and p+Cu collisions with 30 GeV proton beams. The $\phi$ mass modification is sensitive not only to the $K^{+}K^{-}$ modification but also to the branching ratio due to the small Q...

The production of heavy quarks (charm and beauty) in heavy-ion collisions occurs via hard partonic scattering processes at early times. Thus they represent a unique probe of the properties of the quark-gluon plasma (QGP), as they interact with the system throughout its entire lifetime. The heavy-flavour nuclear modification factor ($R_{\rm AA}$) and elliptic flow ($v_{\rm 2}$) are two of the...

The quarkonium production mechanism in elementary proton-proton (pp) collisions remains unclear. Indeed, none of the production models is able to describe it over the full kinematic range. One of the most discriminating observable between models is the polarization state of quarkonium produced in high energy collisions. The ALICE experiment has measured the polarization of inclusive J/$\Psi$...

The production cross sections of open heavy-flavour hadrons in pp and p-Pb collisions are typically described within the factorisation approach as the convolution of the parton distribution functions of the incoming protons, the perturbative QCD partonic cross section, and the fragmentation functions. The latter are typically parametrised from measurements in ${\rm e^+e^-}$ collisions,...

Ultrarelativistic nuclear collisions offer an opportunity to study the production of heavy quarkonia as well as the properties of nuclear matter at extreme temperature and density. Heavy quarks are considered excellent probes to study the properties of the state of matter where quarks and gluons are deconfined, known as quark-gluon plasma (QGP) expected to be formed in nuclear...

In this talk, we present our ongoing work on the inclusion of string interactions, namely rope hadronization and string shoving in heavy ion (PbPb and XeXe) collisions, as an alternative to QGP. Both string shoving, which is the repulsion between two strings, and rope hadronization, where strings in close proximity form higher-order colour multiplets, have been earlier observed to explain...

Open heavy flavors and quarkonium have played important roles in the understanding of the QCD matter produced at high temperatures and low baryon densities. However, they could also provide crucial information about QCD at the lowe center of mass energies employed to probe high baryon density matter at existing or planned facilities.
For example, a nonperturbative contribution to charm...

This poster presents the final recent measurements of $p_{\rm T}$-differential production cross section of charged-particle anti-$k_{\rm T}$ $R = 0.4$ b jets in pp and p--Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV done by the ALICE collaboration. The production cross sections were measured down to $p_{\rm{T}}$ = 10 GeV/$c$, which is lower than in previous measurements of b jets done at...

Two-particle azimuthal correlations triggered by electrons from heavy-flavour hadron decays can be used for heavy-flavour jet studies. By changing the momentum scales of the trigger and associated particles, the heavy-flavour jet structure can be investigated. In pp collisions, heavy-flavour correlations can be used in particular to study the production and fragmentation of heavy quarks.

The study of charm production as a function of charged-particle multiplicity allows the investigation of the role of multi-parton interactions (MPI), and provides insight into the processes occurring at the partonic level and on the interplay between the hard and soft particle production mechanisms in proton--proton (pp) collisions. In this contribution, measurements of open heavy-flavor...

The measurement of heavy-flavour (charm and beauty) production in proton-proton (pp) collisions at the LHC provides a crucial information about quantum chromodynamics (QCD) in high-energy regime. Due to their large masses, heavy quarks are mainly produced in initial hard scattering processes. Therefore, heavy-flavour production cross section represents a primary benchmark for perturbative QCD...

The charm quark at energies of the LHC and above is expected to remain well out of chemical equilibrium,with its abundance dominated by initial stage production, and yet be abundantly enough produced ($N_{c\bar{c}} \simeq 10^2$) for coalescence to be non-negligible.

Using a simple analytically solvable model, we argue that it makes charmonium abundance the ideal probe of remnants of...
