   HoTCoffeeh: Hanbury Brown-Twiss correlation functions and radii from event-by-event hydrodynamics

   Christopher Plumberg🇺🇸 · Ulrich Heinz🇺🇸

   $\text{HoTCoffeeh}$ ($\text{H}$anbury Br$\text{o}$wn-$\text{T}$wiss $\text{Co}$rrelation $\text{f}$unctions and radii $\text{f}$rom $\text{e}$vent-by-$\text{e}$vent $\text{h}$ydrodynamics) is a new computational tool which determines Hanbury Brown-Twiss (HBT) charged pion (${\pi }^{+}$) correlation functions and radii for event-by-event (EBE) hydrodynamics with fluctuating initial conditions in terms of Cooper-Frye integrals, including resonance decay contributions. In this paper, we review the basic formalism for computing the HBT correlation functions and radii with resonance decay contributions included, and discuss our implementation of this formalism in the form of HoTCoffeeh. This tool may be easily integrated with other numerical packages for the purpose of simulating the evolution of heavy-ion collisions and thereby extracting predictions for heavy-ion observables.

   Exploring universality of transversity in p-p collisions

   Marco Radici🇮🇹

   The transversity distribution was recently extracted from deep-inelastic scattering processes producing hadron pairs in the final state. Together with a specific chiral-odd di-hadron fragmentation function, it is involved in the elementary mechanism that generates a transverse-spin asymmetry in the azimuthal distribution of the detected hadron pairs. The same elementary mechanism was predicted to generate an analogous asymmetry when the hadron pairs are produced in proton-proton collisions with one transversely polarized proton. Recently, the STAR Collaboration has observed this asymmetry. We analyze the impact of these data on our knowledge of transversity.
