  • A measurement of the production cross section ratio σ(χb2(1P))/σ(χb1(1P)) is presented. The χb1(1P) and χb2(1P) bottomonium states, promptly produced in pp collisions at √ s = 8 TeV, are detected by the CMS experiment at the CERN LHC through their radiative decays χb1,2(1P) → Υ(1S) + γ. The emitted photons are measured through their conversion to e+e− pairs, whose reconstruction allows the two states to be resolved. The Υ(1S) is measured through its decay to two muons. An event sample… CONTINUE READING
