  In this report, instead to give comprehensive review on two important
research fields during my first term postdoctoral working period: Higgs and
FCNC physics, I will collect part of my recently works on it. Charged Higgs is
the distinguished signature of new physics, in this report, I review my two
works on charged Higgs associated production with top quark and $W$ boson at
hardron colliders. Our researches show that these two charged Higgs production
mechanisms are important channel not only in finding charged Higgs, but also in
studying the quantum structure of new physics. Flavor Changing Neutral Current
(FCNC) processes are forbidden at tree level in the Standard Model (SM), so
they act as the ground to test quantum structure of the SM and also very
important channel in finding new physics beyond the SM. In this report, I focus
on the studies on FCNC processes on linear colliders and in B-factories.
