| contents | Our current {\it impasse}: no new physics seen beyond the $h(125)$ boson. We advocate the {\it general} two Higgs doublet model without $Z_2$ symmetry, allowing extra Yukawa couplings, where we present 5 clear merits. We report on the search effort at LHC for $pp \to tt\bar
c$, then on the new effort of $pp \to bH^+ \to bt\bar b$ search for $H^+$, and comment on our \underline{\bf Decadal Mission} program in Taiwan. Finally, we turn to the $e^+e^- \to H^+H^-
\to c\bar b\bar cb$ program at ILC500 as a {\it what-if} situation at the LHC, demonstrating light $H^+$ reconstruction without $c$-tagging. We then end with discussion and conclusion. |
