Constraints on a left-right-symmetric electroweak theory

Thesis/Dissertation ·
OSTI ID:5209841

Several low-energy quantities are calculated in an attempt to constrain the parameters of a left-right-symmetric theory of electroweak interactions based on the group G = SU(2)/sub L/ x SU(2)/sub R/ x U(1). The quantities calculated are the K/sub L/-K/sub S/ difference, ..delta..m/sub K/, the CP-violation parameters, ..sigma.. and ..sigma..', and the electric dipole moment of the neutron, ..mu../sub n//sup e/. Calculations were performed using the free-quark effective Hamiltonian and generally assume either manifest or pseudo-manifest left-right symmetry. From these calculations an upper bound was placed on the W/sub L/-W/sub R/ mixing angle of /zeta/ approx.< 0.06, a lower bound on the mass of the right-handed W of M/sub R/ approx.> 1.6 TeV, and a tentative lower bound on the W/sub L/-W/sub R/ mixing angle of /zeta/ approx.> 10/sup -5/. If in addition we assume the minimal Higgs sector we find /zeta/ approx.< 1/420 and M/sub R/ approx.< 25 TeV.
