Abstract:
Process of µ+µ- pair production in hard Double Pomeron Exchange (DPE) is studied on the CMS (LHC) at energy √s = 14 TeV. In the zero order of as this process is sensitive only to quark distributions. Using H1(DESY) data for quark-antiquark parton distributions in the Pomeron, calculations were performed to pre¬dict the quark-antiquark component of the parton distribution and the estimate is that quark-antiquark does not exceed 5%. Using CMSSW package, the events of the process were reconstructed. The method for estimation of valent quark(antiquark) contribution in the parton structure of the Pomeron is developed. This method could be used at the experimental data performance obtained on the CMS detector.
