Abstract

It is shown that, in the framework of four-color symmetry, the restrictions on the masses of scalar leptoquarks are much smaller than those of vector leptoquarks. The processes \({{l}_{i}} \to {{l}_{j}}\gamma \) with the lepton flavor violation, the anomalous magnetic moment of the muon, and the magnetic moment of the neutrino are investigated. It is shown that, when the values of matrix \(K_{2}^{L}\) of additional fermionic mixing are taken into account, restrictions on the masses of scalar leptoquarks with electric charges 2/3 and –1/3 constitute an order of several TeV.
