Υ cross section in p+p collisions at √s=200 GeV

Υ cross section in p+p collisions at √s=200 GeV

We report on a measurement of the Υ(1S+2S+3S)→e+e- cross section at midrapidity in p+p collisions at √s=200 GeV. We find the cross section to be 114±38(stat+fit)-24+23(syst) pb. Perturbative QCD calculations at next-to-leading order in the color evaporation model are in agreement with our measurem...
