Dynamical evolution of critical fluctuations with second-order baryon diffusion coupled to a chiral condensate

p–ϕ femtoscopic correlation analysis using a dynamical model

Kenshi Kuroki, Tetsufumi Hirano

EPJ Web of Conferences, 316 03009-03009, Jan 27, 2025

We analyse the p–ϕ correlation functions in high-multiplicity proton+ proton collisions at the LHC using a dynamical model, DCCI2, and discuss the effects of collision dynamics on the p–ϕ femtoscopic study. Collision dynamics, such as collective expansion and hadronic rescatterings, leads to the relative momentum-dependent non-Gaussian source functions. This results in deviations in the correlation functions compared to those using the Gaussian source function adopted in existing studies. Our analysis shows the importance of using the source functions that reflect more realistic collision dynamics for future precision analysis of hadron interactions via femtoscopy.

Dynamics of causal hydrodynamic fluctuations in an expanding system

Shin-ei Fujii, Tetsufumi Hirano

EPJ Web of Conferences, 296 02005-02005, Jun 26, 2024

We develop a framework of causal hydrodynamic fluctuations in onedimensional expanding system performing linearisation of the hydrodynamic equations around the boost invariant solution. Through the description of spacetime evolution of thermodynamic variables and flow velocity, we find a novel phenomenon that the structure of thermodynamic variables is almost frozen. We also show that two-particle correlation functions of final hadrons after freezeout are closely related with the mass of hadrons and properties of the medium such as viscosity, relaxation time and equation of state.
