Coupling constants of the standard model according to LEP data and scale of the left-right symmetry breaking
Asatryan G. M., Matinyan S. G.
The scales of the breaking of SO (10) &ndSU(2)R symmetry are calculated in a grand unified model based on the SO(10) group with intermediate left-right symmetry. New LEP data on the coupling constants of the standard model are taken into account The results correspond to experimental data from the search for an instability of the proton.
