Estimating scalar-leptoquark masses from the muon anomalous magnetic moment within the four-color symmetry model

摘要

The contributions to the muon anomalous magnetic moment from the doublets of scalar leptoquarks having a four-color origin are studied. It is shown that experimental data on the muon anomalous magnetic moment are compatible with the existence of relatively light scalar leptoquarks (of mass about 1 TeV or below).
