| Özet |
| Differential cross sections as a function of transverse momentum p T are presented for the production of ϒ (n S)(n= 1, 2, 3) states decaying into a pair of muons. Data corresponding to an integrated luminosity of 4.9 fb− 1 in pp collisions at s= 7 TeV were collected with the CMS detector at the LHC. The analysis selects events with dimuon rapidity| y|< 1.2 and dimuon transverse momentum in the range 10< p T< 100 GeV. The measurements show a transition from an exponential to a power-law behavior at p T≈ 20 GeV for the three ϒ states. Above that transition, the ϒ (3 S) spectrum is significantly harder than that of the ϒ (1 S). The ratios of the ϒ (3 S) and ϒ (2 S) differential cross sections to the ϒ (1 S) cross section show a rise as p T increases at low p T, then become flatter at higher p T. |
