211. Probing the structure of $f_{0}$(980) from the elliptic flow in p-Pb collisions at the LHC

Yili Wang (Peking University)

24/03/2026, 08:45

Oral Presentation

The study of exotic hadrons has long been a topic of great interest for the understanding of Quantum Chromodynamics (QCD). As one of the light exotic hadrons, the structure and constituent quark content of $f_0(980)$ have been debated for decades, with theories suggesting it could be a tetraquark state ($s\bar sq\bar q$) or a hadronic molecule ($K\bar K$). Assuming that the $f_0(980)$ is a...

234. Freeze-out of charge fluctuations in the QGP: D-measure at the LHC

Roman Poberezhniuk (University of Houston)

24/03/2026, 09:05

Oral Presentation

The D-measure of net-charge fluctuations quantifies the variance of net charge in strongly interacting matter. It was introduced over 20 years ago as a potential signal of quark-gluon plasma (QGP) in heavy-ion collisions, where it is expected to be suppressed due to the fractional electric charges of quarks. Measurements have been performed at RHIC and LHC, but the conclusion has been elusive...

77. Search of exotic resonances in proton-proton and Λnn hypernuclei in Pb--Pb collisions with ALICE

Sawan Sawan (NISER, India)

24/03/2026, 09:25

Oral Presentation

Exotic particles are those whose internal structure is not well understood and cannot be accurately described by state-of-the-art theoretical models or predictions. Current hypotheses regarding the nature of these exotic particles range from conventional mesons and baryons to multiquark configurations (such as tetraquarks), glueballs composed of valence gluons, and molecularly bound states...

186. Measurement of thermal dielectron production in O+O collisions at $\sqrt{s_{\mathrm{NN}}}=200$ GeV with the STAR experiment

Zihan Liu (Univ. of Science and Technology of China)

24/03/2026, 09:45

Oral Presentation

Thermal dielectrons serve as an ideal thermometer to probe the average temperature of the hot and dense QCD medium created in heavy-ion collisions. Previous measurements over a wide range of collision energies and collision systems exhibit consistent temperature trends, indicating significant contributions from the quark-gluon plasma (QGP). Oxygen-oxygen (O+O) collisions, with an effective...

76. Constraining the hadronic phase in light-ions with resonance measurements with ALICE

Sarjeeta Gami (NISER, India)

24/03/2026, 10:05

Oral Presentation

Hadronic resonances are a valuable tool for studying the strongly interacting matter created in relativistic heavy-ion collisions. Their short lifetimes make them sensitive probes of the late hadronic stage, where competing rescattering and regeneration processes can modify momentum and azimuthal distributions. Rescattering of decay daughters can alter their momenta, preventing the...

205. Heavy Quark Recombination Across Collision Systems: Meson and Baryon production

Vincenzo Minissale (Università degli Studi di Catania - INFN Catania)

25/03/2026, 08:45

Oral Presentation

Measurements of heavy baryon production in pp, pA and AA collisions from RHIC to top LHC energies have recently attracted more and more attention, currently representing a challenge for the heavy-quark hadronization theoretical understanding. In such experiments there have been many indications of the formation of a deconfined phase of quarks and gluons called the quark-gluon-plasma (QGP)....

42. Charm-strange meson production by recombination in heavy ion collisions at \sqrt{s_{NN}}=5.02 TeV

Sungtae Cho (Kangwon National University)

25/03/2026, 09:05

Oral Presentation

We discuss charm-strange mesons, Ds, Ds, Ds0(2317), Ds1(2460), and X(3915) mesons produced from charm and strange quarks in the quark-gluon plasma in heavy-ion collisions at \sqrt{s_{NN}}=5.02 TeV. We first investigate the transverse momentum distribution of charm and strange quarks at \sqrt{s_{NN}}=5.02 TeV in the quark-gluon plasma based on transverse momentum distributions of \phi and D^0...

142. Probing Charm Quark Hadronisation with Strange and Baryonic Probes

Nihar Ranjan Saha (Purdue University)

25/03/2026, 09:25

Oral Presentation

The hadronisation of charm quarks within the strangeness-rich environment of the Quark-Gluon Plasma (QGP) offers a unique laboratory for studying non-perturbative QCD dynamics. We present new measurements from the CMS experiment utilising the high-statistics lead-lead (PbPb) collision datasets from Run 2 and Run 3. This work features a high-precision measurement of the elliptic ($v_2$) and...

260. The role of strangeness and baryon enhancement in heavy-quark hadronization from pp to Pb--Pb collisions with ALICE

Fabrizio Chinu (Univ. of Torino)

25/03/2026, 09:45

Oral Presentation

Understanding charm-quark hadronization is key to characterizing the quark–gluon plasma formed in heavy-ion collisions. Measurements of strange and non-strange charm hadrons across collision systems probe hadronization mechanisms, particularly in Pb–Pb collisions where abundant strangeness is expected to enhance recombination effects and provide stringent tests of statistical-hadronization...

214. sPHENIX new measurements of heavy flavor hadronization in p+p collisions at RHIC

Charles Hughes (Lehigh University)

25/03/2026, 10:05

Oral Presentation

sPHENIX is a next-generation experiment at RHIC for jet and heavy-flavor physics which was fully commissioned in 2024. Using its novel streaming-readout-capable, precision tracking system, sPHENIX collected 100 billion unbiased p+p collisions, and a further sample of minimum-bias Au-Au collisions, in Run-24. A key measurement of the sPHENIX heavy flavor physics program are measurements of the...
