Talk

Quarkonia are excellent probes of deconfinement in heavy-ion collisions. For $J/\psi$, a bound state of $c\overline{c}$ quarks, the (re-)generation is found to be the dominant production mechanism at the LHC energies. On the other hand, the non-prompt component of $J/\psi$ production originating from b-hadron decays allows one to access the interaction of b-quarks with the QGP. Polarization and...

38. Detailed study of bottomonium suppression with the measurement of the $\mathrm{{\rm Y}}$(3S) meson in PbPb collisions at 5.02 TeV with CMS

Heavy-flavor and Quarkonia

Talk

Because of the different binding energies, bottomonium mesons are particularly useful probes to understand the thermal properties of quark-gluon plasma. Previously, CMS observed the sequential suppression of $\mathrm{{\rm Y}}$(1S), $\mathrm{{\rm Y}}$(2S), and $\mathrm{{\rm Y}}$(3S) in heavy ion (AA) collisions, which was widely accepted as evidence for the QGP formation. However, the $\mathrm{{\rm Y}}$(3S) yield was...

Heavy-flavor and Quarkonia

Talk

To understand the in-medium effects of quarkonia in heavy ion collisions, it is necessary to perform differential studies of various observables to have a global picture of the quarkonium dynamics in the quark-gluon plasma (QGP). Recent results in proton-proton collisions have suggested that J/$\psi$ mesons are produced with much more jet activity than model predictions, which indicate that...

28. $\psi$(2S) production and nuclear modification factor in nucleus-nucleus collisions with ALICE

Heavy-flavor and Quarkonia

Talk

Charmonium production is a probe sensitive to deconfinement in nucleus-nucleus collisions. The production of J/$\psi$ via regeneration within the QGP or at the phase boundary has been identified as an important ingredient for the description of the observed centrality and $p_T$ dependence at the LHC. $\psi$(2S) production relative to J/$\psi$ is one possible discriminator between the two...

48. Measurement of non-prompt and prompt $D^0$ azimuthal anisotropy in Pb-Pb collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=$ 5.02 TeV

Heavy-flavor and Quarkonia

Talk

Heavy quarks are primarily produced via initial hard scatterings, and thus carry information about the early stages of the Quark-Gluon Plasma (QGP). Measurements of the azimuthal anisotropy of the final-state heavy flavor hadrons provide information about the initial collision geometry, its fluctuation, and more importantly, the mass dependence of energy loss in QGP. Due to the larger bottom...

49. New insights on heavy flavor dynamics and hadronization from small to large collision systems from ${\mathrm{\Lambda }}_c^{+}$ production with CMS

Heavy-flavor and Quarkonia

Talk

The observation of collectivity signals in small hadronic collisions raises the question of whether the tiny droplet of quark-gluon plasma can form in small systems. Dynamics and hadronization of heavy flavor quarks in small-system collisions provide a powerful tool to address the origin of observed collective phenomena because of their early production time and sensitivity to the finite...

50. Studies of heavy flavor dynamics using $B^{+}$, $B_s^0$ and $B_c$ mesons with CMS

Heavy-flavor and Quarkonia

Talk

Heavy quarks are one of the most important probes to study the properties of quark-gluon plasma (QGP). Hadronization of beauty quarks is not as well understood as in the charm sector. Illuminating the hadronization mechanism is crucial for extracting the transport properties of the QGP. We present new results on nuclear modification factors of $B_s^0$ and $B^{+}$ mesons and their yield ratios in...

In this contribution the nuclear modification factor ($R_{\mathrm{AA}}$) of prompt charm hadrons and leptons from heavy-flavour hadrons decays measured in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV by the ALICE Collaboration are presented. The measurement of heavy-flavour leptons in Xe-Xe collisions is also discussed. Heavy quarks are a very suitable probe to investigate the quark-gluon...

In this contribution, the final measurements of the centrality dependence of $R_{\mathrm{A}\mathrm{A}}$ of non-prompt ${\mathrm{D}}^0$ and electrons from beauty hadron decays in Pb-Pb collisions at $\sqrt{s_{\mathrm{N}\mathrm{N}}}$ = 5.02 TeV will be presented. These measurements provide important constraints to the in-medium mass-dependent energy loss and hadronization of the beauty quark. The integrated non-prompt...

Heavy-flavor and Quarkonia

Talk

The early production of heavy-flavour partons makes them an excellent probe of the dynamical evolution of QCD systems. Jets tagged by the presence of a heavy-flavour hadron give access to the kinematics of the heavy partons, and along with correlation measurements involving heavy-flavour hadrons allow for comparisons of their production, propagation and fragmentation across different systems....

97. Measurements of $J/\psi$ production in Ru+Ru and Zr+Zr collisions at $\sqrt{s_{NN}}=200$ GeV from STAR experiment

Heavy-flavor and Quarkonia

Talk

Quankonia are an important probe to study the properties of the quark-gluon plasma (QGP) created in heavy-ion collisions. In particular, the $J/\psi$ nuclear modification factor, $R_{AA}$, probes hot nuclear matter effects, such as the dissociation arising from the color screening effect and and the regeneration by deconfined charm and anti-charm quarks. On the other hand, the $J/\psi$...

153. In-medium transport of $X$(3872) and $B_c$ at the LHC

Heavy-flavor and Quarkonia

Talk

We investigate the in-medium kinetics of the X(3872) and $B_c$ particles in ultra-relativistic heavy-ion collisions (URHICs). Our transport approach, previously employed for charmonia and bottomonia, is governed by two transport parameters: the equilibrium limit and inelastic reaction rate. The equilibrium limits of X(3872) and $B_c$ are entirely determined by the particles' masses and the...

132. ALICE determines the scattering parameters of D mesons with light-flavor hadrons

Emma Chizzali (Technische Universitaet Muenchen (DE))

Heavy-flavor and Quarkonia

Talk

The strong interaction among D mesons and light-flavor hadrons was completely out of experimental reach until recently. The scattering parameters governing elastic and inelastic D-pion/kaon/proton collisions are completely unknown. This poses strong limitations not only to the search of molecular states composed of charm and non-charm hadrons, but also to the study of the rescattering of charm...

135. Heavy-flavour meson and baryon production in high-energy nucleus-nucleus collisions

Heavy-flavor and Quarkonia

Talk

Recent experimental measurements display an enhanced production of charmed baryons in high-energy nucleus-nucleus collisions. Quite surprisingly the same is found in proton-proton collisions, in which the relative yields of charmed baryons do not agree with the expectations based on e+e- collisions and with the predictions of those QCD event generators in which the hadronization stage is tuned...

165. Probing the electromagnetic field with heavy quarks and $Z^0$ decaying leptons and $Z^0$ leptonic invariant mass in ultrarelativistic heavy ion collisions

Heavy-flavor and Quarkonia

Talk

Ultra-relativistic heavy ion collisions are expected to generate a huge electromagnetic (e.m.) field that is envisaged to induce several effects on hot QCD matter including the possibility of local parity and local parity and charge conjugation symmetry violations. A direct signature of such e.m. fields and a first quantitative measurement of its strength and lifetime are still missing.
We...

Heavy-flavor and Quarkonia

Talk

The theoretical analysis of experimental observations, such as the mass hierarchy effect, often neglects some ingredients, which may be proven to have a significant impact. The forthcoming measurements at RHIC and LHC will generate heavy flavor data with unprecedented precision, providing an opportunity to utilize high-pT heavy flavor data to analyze the interaction mechanisms in the...

Heavy-flavor and Quarkonia

Talk

We discuss elliptic and triangular flow of charmonia in heavy ion collisions based on the coalescence model. Starting from the investigation on transverse momentum distributions of charmonium states, we calculate elliptic and triangular flow of charmonium states produced at quark-hadron phase boundary by quark recombination. We show that the wave function distribution of charmonium states...

Heavy-flavor and Quarkonia

Talk

One of the present challenge for the theoretical understanding of heavy-quark hadronization is represented by the description of the measurements of heavy baryon production in $pp$, $pA$ and $AA$ collisions from RHIC to top LHC energies.
The ${\mathrm{\Lambda }}_c/D^0$ ratio observed in $AA$ collisions has a value of the order of the unity, and experimental measurements in $pp$ collisions at both...

Heavy-flavor and Quarkonia

Talk

The propagation of heavy quarks (HQs), charm and bottom, in the quark-gluon plasma (QGP) is described by means of a full Boltzmann transport approach. The non-perturbative dynamics and the interaction between HQs and the bulk is taken into account by means of a Quasi-Particle Model. Including the description of the intense electromagnetic and vortical fields, we discuss their impact on the...

Heavy-flavor and Quarkonia

Talk

The phenomenon of strangeness enhancement, originally proposed as a signature of quark-gluon plasma formation, has received considerable new interest following recent observations in small collision systems. LHCb is uniquely well suited to study such effects in the heavy quark sector, down to very low transverse momentum. Here we will present new LHCb results on the production rates of...

Heavy flavour and quarkonium production at hadron colliders provides an important test of the theory of Quantum Chromodynamics (QCD). The PHENIX experiment has a comprehensive physics program that studies open heavy flavor and quarkonium production in p/d+A and A+A collisions at the Relativistic Heavy Ion Collider (RHIC). It is critical to measure both open heavy flavor and quarkonium in...
