Kihyeon Cho Theory-Experiment To develop the fusion system of pheno- menology and data analysis Based on this system, we apply Monte Carlo system for experiments. To apply this system to hadron collider experiments in order to study the standard model (SM) and new physics (NP). To apply new tools to future experiments Belle-II, LHC, etc. 12

Kihyeon Cho Higgs mass at Tevatron 13  Exclusion region on SM Higgs boson mass at 95% C.L. at Tevatron (Upper Figure).  Higgs Production of the BMSSM with spontaneous CP violation via Higgs-strahlung Process (W,Z) at Tevatron (Lower Figure).  We can apply to the Higgs boson mass of the BMSSM by using the exclusion potential of the SM Higgs boson mass. => Under Way
