| dc.description | The contributions of the scalar leptoquark doublets into widths of the $K^0_L \to e^{\mp} μ^{\pm}$, $B^0 \to e^{\mp} τ^{\pm}$ decays are calculated in MQLS model with Higgs mechanism of the quark-lepton mass splitting. The resulted mass limits for the scalar leptoquarks are investigated in comparision with those for vector and chiral gauge leptoquarks. It is shown that the scalar leptoquark mass limits are essentially weaker (about $200 GeV$) than those (a few hundreds $TeV$) for gauge leptoquarks. The search for such scalar leptoquark doublets at LHC and the search for the leptonic decays $ B^0 \to l^+_i l^-_j $ are of interest. | |
