An SU (3)_L×U(1)_X Electroweak Model

  • We studied an SU(3)L×U(1)X electroweak model. By requiring M2z1-M2w/ cos2θw to be less than experimental value we abtain a lower bound on MZ′ The relation between MZ′ and MU (MV) then gives a lower bound on MU (MV). We further consider the KL-KS mass difference due to Z′ exchange and obtain stronger lower bounds on MZ′ and MU (MV).

Abstract: We studied an SU(3)L×U(1)X electroweak model. By requiring M2z1-M2w/ cos2θw to be less than experimental value we abtain a lower bound on MZ′ The relation between MZ′ and MU (MV) then gives a lower bound on MU (MV). We further consider the KL-KS mass difference due to Z′ exchange and obtain stronger lower bounds on MZ′ and MU (MV).
