Anomalous Gauge Interactions of the Higgs Boson: Precision Constraints and Weak Boson Scatterings

Hong-Jian He, Yu-Ping Kuang, C. -P. Yuan +1

Interaction of Higgs scalar (H) with weak gauge bosons (V=W,Z) is the {\it key} to understand electroweak symmetry breaking (EWSB) mechanism. New physics effects in the HVV interac…

Lepton flavor violation in lopsided models and a neutrino mass model

Xiao-Jun Bi

A widely adopted theoretical scheme to account for the neutrino oscillation phenomena is the see-saw mechanism together with the ``lopsided'' mass matrices, which is generally real…
