abstract
Using a viscous hydrodynamic model coupled to a hadronic cascade code, numerous features of the dynamics and equilibrium properties are explored for their impact on femtoscopic measurements. The equation of state, viscous parameters and initial conditions are investigated. We find that femtoscopy is affected by numerous model features at the 10% level, and that by including features and adjusting unknown parameters, one can explain experimental source size measurements to better than 10%.

Two-particle number and transverse momentum balance function with event-topology in pp collisions at $\sqrt{s}=13$ TeV
In PYTHIA8 and EPOS-LHC simulations of pp collisions, charge balance function widths narrow with multiplicity, are narrower in jet-like than isotropic events, and EPOS core-on/off differences point to radial flow as the localizing mechanism.
