Dear convenors,

I sent my email to express my intent to submit an abstract submission for QM 23 to the star-talks channel but to make sure I am sending the same here once again. For now, my abstract will be the same as the one submitted for IS 2023. Here is the brief below.

Title: Measurement of femtoscopic correlation function between D0 mesons and charged hadrons in Au+Au collisions at √sNN = 200 GeV in STAR

Heavy quarks are produced in hard partonic scatterings at the very early stage of heavy-ion collisions and they experience the whole evolution of the created Quark-Gluon Plasma medium. Femtoscopic correlations, i.e., two-particle correlations at low relative momentum, are sensitive to the final-state interactions and the extent of the region from which correlated particles are emitted. A study of such correlations between charmed mesons and identified charged hadrons could shed light on their interactions in the hadronic phase and the interaction of charm quarks with the bulk partons. We will present femtoscopic correlations of D0-π, D0-K, D0-proton pairs at mid-rapidity in Au+Au collisions at √sNN = 200 GeV using data taken in the year 2014 and 2016 by the STAR experiment. D0 mesons are reconstructed via the K--π+ decay channel using topological criteria enabled by the excellent track-pointing resolution provided by the Heavy Flavor Tracker. We will present the femtoscopic correlation function for D0 transverse momentum above 1 GeV/c in the 0-80% centrality.

So, far we haven't observed any correlation signal, we have the plan to set an upper limit to calculate source size. 

Regards,

Priyanka
