Abstract

We consider the contributions of the exotic quarks and gauge bosons to the mass difference between the short- and the long-lived neutral kaon states in the SU(3)_C\ifmmode×\else\texttimes\fiSU(3)_L\ifmmode×\else\texttimes\fiU(1)_N model. The lower bound M_Z^\ensuremath'\ensuremath∼14 TeV is obtained for the extra neutral gauge boson Z^\ensuremath'0. Ranges for values of one of the exotic quark masses and quark mixing parameters are also presented.
