Description

The phi meson is a versatile probe for studying the hot medium created in heavy ion collisions. Its low hadronic interaction cross section can provide important insights into the early time dynamics of the collective expanding medium. In this analysis, the performance of phi meson reconstruction via the decay channel of K+K- is presented for high multiplicity events in 5.02 TeV pPb and 2.76 TeV PbPb collisions using the CMS detector. The yield of phi mesons is extracted in the transverse momentum range of 2-20 GeV/c. Technique of extracting second-order anisotropy harmonics (v$_2$) of phi mesons from long-range two-particle correlations will also be discussed.
