Contract Type FiledOctober 11th, 2018The examples of the processes where the light scalar particle could be produced in a direct p-p collision in the deep inelastic scattering (DIS) are given in Fig. 2.1. This production channel for the case of proton fixed-target experiment was studied in [182]. It was found that the main contribution to this type of production comes from gluon fusion with a top quark in the loop because of the large Yukawa coupling of the top quark. The production probability of this channel is shown in Fig. 2.2. The production probability is small because it competes with QCD processes.
