Direct photons in experiment polex

Two basic directions in the modern high-energy physics are reviewed to study new particles (gluonic states, mixed quark-gluon systems, t-quarks, the Higgs bosons, etc.) as well as for further investigation into the structure of the known particles. Feasibility of a direct experiment on determination of the Δ G value is discussed. It is proposed to use the reaction of inclusive fast photon production at the angle of 90 deg. in the p-p -> γ + X c.m.s. at UNK energies for determination of gluon contribution into proton spin. The proposed reaction is discussed at quark-gluon level. It is noted that the experiment will allow to solve the problem, given the value of transfered momentum (5-6 GeV) is achieved. 1 fig
