摘要：

We calculate phi meson transverse momentum spectra in p+p collisions as well as their nuclear suppressions in central A+A collisions both at the RHIC and the LHC in LOandNLOwith theQCD-improved partonmodel. We have included the parton energy loss effect in a hot/dense QCD medium with the effectively medium-modified phi fragmentation functions in the higher-twist approach of jet quenching. The nuclear modification factors of the f meson in central Au + Au collisions at the RHIC and central Pb + Pb collisions at the LHC are provided, and nice agreement of our numerical results at NLO with the ALICE measurement is observed. Predictions of the yield ratios of neutral mesons such as phi/pi(0), phi/eta and phi/rho(0) at large p(T) in relativistic heavyion collisions are also presented for the first time.
