ϕ(1020) and ω(782) Mesons from Dielectron Decays at STAR
Creators
Description
The measurement of masses, widths, transverse momentum spectrum, and yields of ϕ→e+e− at mid-rapidity (|y|<1) from STAR experiment in Au + Au collisions at √(sNN)=200 GeV are presented and compared to the ϕ meson result from the hadronic decay channel. The ω→e+e− spectrum is also presented. Particle identification based on the STAR Time-of-Flight (TOF) detector upgrade in conjunction with ionization energy-loss (dE/dx) measurements from the Time Projection Chamber (TPC) is used for a clean electron and positron identification
