271. Detection of medium induced parton momentum broadening using photon-tagged jets with the CMS detector

Molly Taylor (Massachusetts Inst. of Technology (US))

06/04/2022, 14:40

Strongly coupled systems

Oral presentation

Azimuthal angle ($\mathrm{\Delta }\varphi$) and transverse momentum ($p_{\mathrm{T}}$) correlations of isolated photons and associated jets, which are sensitive to medium induced parton momentum broadening, are reported for the first time with the latest high statistics pp and PbPb data recorded with the CMS detector at $\sqrt{s_{{}_{\mathrm{NN}}}}=$ 5.02 TeV. The fully corrected photon+jet azimuthal...

210. New experimental frontiers in the study of many-body nuclear interactions with ALICE

Strongly coupled systems

Oral presentation

Exploring the strong interaction among hadrons, the ALICE Collaboration has for the first time extended the experimental measurements from two- to three-body interactions. These measurements provide unique information on many aspects of strongly-coupled systems, like the genuine three-body interaction, the formation of light nuclei and the search for exotic bound states. Among those, many-body...

825. Heavy-Light Susceptibilities in a Strongly Coupled Quark-Gluon Plasma

Shuai Liu (Hunan University)

Strongly coupled systems

Oral presentation

Quark number susceptibilities as computed in lattice QCD are commonly believed to provide insights into the microscopic structure of QCD matter, in particular its degrees of freedom. We generalize a previously constructed partonic $T$-matrix approach to finite chemical potential to calculate various susceptibilities, in particular for configurations containing a heavy charm quark. At vanishing...

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

Fabrizio Grosa (CERN)

Strongly coupled systems

Oral presentation

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...

600. Charm and Bottom quark energy loss and flow measurements in Au+Au collisions by the PHENIX experiment

Takashi Hachiya (RIKEN)

06/04/2022, 16:00

Strongly coupled systems

Oral presentation

The energy loss of quarks when travelling a QGP medium is expected to depend on their mass. Heavy quarks causes a dead cone region along the direction of the quark where no energy is lost by gluon bremsstrahlung. This effect can be measured by comparing the nuclear modification factors of hadrons made of light and heavy quarks. The heavy quark coupling with the thermalized QGP is also an...

780. The splitting of directed flow for identified light hadrons (\pi, K, and p) and strange baryons (\Xi and \Omega) in Au+Au and isobar collisions at STAR

Ashik Ikbal

Strongly coupled systems

Oral presentation

In relativistic heavy-ion collisions, the directed flow ($v_1$) of hadrons can provide insights into the ultra-strong electromagnetic (EM) field~[1-2], the constituent quark content of hadrons~[3], and the role of transported quarks~[4]. Here, the first measurement is reported for rapidity-odd directed flow of $\mathrm{\Xi }$ and $\mathrm{\Omega }$ in Au+Au collisions at $\sqrt{s_{NN}}=$ 19.6, 27, and 200 GeV, as...

208. Understanding the nature of f${}_0$(980) via K${}^{+}$K${}^{-}$ correlation and production yield with ALICE

Neelima Agrawal (Universita e INFN, Bologna (IT))

06/04/2022, 16:40

Strongly coupled systems

Oral presentation

The f${}_0$(980) resonance was observed several years ago in $\pi \pi$ scattering experiments. Despite a long history of experimental and theoretical studies, the nature of this short-lived resonance is far from being understood and there is no agreement about its quark structure. According to different models, it has been associated with a meson, considered as a tetraquark, or as a KK molecule....
