47. Isospin-Driven Splitting of Chemical Potentials in Isobar Collisions from Lattice QCD

Jia Ni

Strong magnetic fields produced in relativistic heavy-ion collisions can modify conserved-charge fluctuations and their associated chemical potentials. The Ru and Zr isobars share the same mass number, $A=96$, but have different charge-to-baryon ratios, making Ru+Ru and Zr+Zr collisions a controlled setting for isolating isospin effects. In this talk, we will present first-principles,...

39. Probing Hydrodynamic Applicability and Partonic Collectivity in O+O and Ne+Ne Collisions

Recent O+O and Ne+Ne collisions at the LHC provide a controlled laboratory to test the applicability of relativistic hydrodynamics and search for signatures of quark-gluon plasma formation in small systems. We study O+O and Ne+Ne collisions at $\sqrt{s_{\mathrm{NN}}}=5.36~\mathrm{TeV}$ using two complementary approaches.

First, we compare viscous anisotropic hydrodynamics (VAH) with...

7. Extracting the QCD speed of sound in the presence of quantum fluctuations

Yushan Mu (Fudan)

It has recently been realized that in the ultra-central heavy-ion collisions, mean transverse momentum of hadrons contains the information of the fundamental thermodynamic properties of quark-gluon plasma (QGP). In particular, in nucleus-nucleus collisions, the linear correlation between the mean transverse momentum and the charged multiplicity is attributed to the QCD speed of sound, which...

66. Transverse-momentum differential radial flow fluctuations across collision systems with CMS

Dr Rohit Kumar Singh (Shandong University)

18/10/2026, 16:50

Event-by-event fluctuations of the mean transverse momentum of particles provide a direct probe of collective radial expansion of the system formed in high-energy collisions. We present the first measurement of transverse-momentum-dependent radial flow fluctuations, characterized by the observable $v_0(p_{\mathrm{T}})$, in small collision systems. The measurement is performed using CMS data...

57. Non-hydrodynamics simplified

禛康 陆 (香港中文大学（深圳）)

18/10/2026, 17:10

Hydrodynamics can describe the thermalized quark-gluon plasma phase of heavy-ion collisions. Extending its validity to pre-equilibrium stages requires accounting for short-lived non-hydrodynamic modes. In this talk, I present a method that retains selected information from these modes to extend the validity of hydrodynamics beyond the conventional hydrodynamic regime. I apply this method to...
