Dilepton Production in p plus p, Au plus Au collisions at root s(NN) = 200 GeV and U+U collisions at root s(NN)=193 GeV

摘要

In this contribution we report e(+) e(-) spectra with various invariant mass and p(T) differentials in Au+Au collisions at root s(NN)=200 GeV and U+U collisions at root s(NN)=193 GeV. The structure of the t (-t approximate to p(T)(2)) distributions of these mass regions will be shown and compared with the same distributions in ultra-peripheral collisions. Additionally, this contribution discusses first measurements of mu(+)mu(-) invariant mass spectra from STAR's recently installed Muon Telescope Detector (MTD) in p+p and Au+Au collisions at root s(NN) = 200 GeV.
