摘要：

The low-energy manifestations of a minimal extension of the electroweak standard model based on the quark-lepton symmetry SU(4) V. SU(2) L. GR of the Pati-Salam-type are analyzed. Given this symmetry the third type of mixing in the interactions of the SU(4) V leptoquarks with quarks and leptons is shown to be required. An additional arbitrariness of the mixing parameters could allow, in principle, to decrease noticeably the lower bound on the vector leptoquark mass originated from the low-energy rare processes, strongly suppressed in the standard model.
