摘要

Leptoquarks are hypothetical particles carrying both baryon number (B) and lepton number (L).The possible quantum numbers of leptoquark states can be restricted by assuming that their direct interactions with the ordinary SM fermions are dimensionless and invariant under the standard model (SM) gauge group.Table 1 shows the list of all possible quantum numbers with this assumption [1].The columns of SU(3)C,SU(2)W,and U(1)Y in Table 1 indicate the QCD representation,the weak isospin representation,and the weak hypercharge,respectively.The spin of a leptoquark state is taken to be 1 (vector leptoquark) or 0 (scalar leptoquark).
