Abstract

Production of b \(\bar b\) -pairs in the process of hard double-Pomeron exchange (DPE) of protons has been studied on the CMS plant at the LHC accelerator energies of \(\sqrt s = 7\) TeV. The method for estimation of valent parton contribution in the Pomeron structure is developed. On the basis of H1 (DESY) data for parton distributions in Pomeron the calculations were performed to predict the hard (valent) parton components in the Pomeron structure. The contribution of valent partons is estimated about 61%. Using program package CMSSW, the event reconstruction of studied process also was made. This method can be applied to the available experimental data from the CMS detector.
