Description
Hadronic resonances can act as useful probes to examine the hadronic phase in ultra-relativistic heavy-ion collisions. In addition, high $p_{T}$ resonances could probe not only the hadronic phase but also the partonic phase if they are created very early in jet fragmentation. Hadron-resonance angular correlations could help to preferentially select high transverse momentum resonances coming from the jet or out of the jet region.
In this analysis, the $K^{*0}(892)$ and $\phi(1020)$ production in and out of jets are studied by exploiting their angular correlation with respect to the highest transverse momentum particle, used as a proxy for the jet axis. A first look at the method using data from lead-lead collisions at $\sqrt{s_\mathrm{NN}}$= 5.02 TeV will be presented.
