Heavy Flavor and Strangeness in Jets and Jets-Medium Interactions*

Advances in detector technologies and data analysis techniques have firmly established jet measurements as experimental tools for exploring matter produced in heavy-ion interactions. On par, our theoretical understanding of the interactions of hard-scattered partons with a hot Quark-Gluon Plasma (QGP) medium formed in such collisions expanded dramatically.

In recent experimental jets studies, special attention is given to identifying the flavor of a hard-scattered parton creating the shower, specifically the jets with/from heavy flavor or strange quarks. Measurements of the heavy flavor jet production rates and internal substructure in elementary collisions allow precision tests of Quantum Chromodynamics on flavor dependence of parton fragmentation, accompanying gluon radiation, and hadronization effects. Combining such data with heavy-ion measurements of “flavored” jets opens new opportunities for investigating mass-dependent effects of in-medium parton energy loss and parton-medium interactions in QGP.

In this talk, I will review recent experimental results on in-jet heavy flavor and strangeness measurements.
