Abstract

The production of pairs of scalar particles belonging to an arbitrary color multiplet of the SU c (3) group in proton-proton collisions is considered, and the differential and total cross sections for the corresponding partonic processes are obtained. The total cross section for the production of octets of scalar gluons F 1 and F 2 at LHC is calculated versus their mass, and their dominant decays, which are necessary for their searches, are discussed. It is shown that, for mF 1 ≲ 1000 GeV, the number of signal \( t\tilde tb\tilde b \) events fromthe decays of the scalar gluon F 1 may exceed substantially (by not less than three standard deviations) the Standart Model background and that the cross section for the production of scalar gluons F 1 and F 2 having masses in the region m F1,m F2 ≲ 1300 GeV may be sufficient for the efficient (N events ≲ 100–1000 at L = 10–100 fb−1) production of these particles at LHC.
