چکیده
We examine the charmless hadronic B decay modes in the context of R-parity violating (Rp / ) supersymmetry. We try to explain the large branching ratio (compared to the Standard Model (SM) prediction) of the decay B → ηK. There exist data for other observed η(′) modes and among these modes, the decay B0 → ηK∗0 is also found to be large compared to the SM prediction. We investigate all these modes and find that only two pairs of Rp / coupling can satisfy the requirements without affecting the other B → PP and B → V P decay modes barring the decay B → φK. From this analysis, we determine the preferred values of the Rp / couplings and the effective number of color Nc. We also calculate the CP asymmetry for the observed decay modes affected by these new couplings. [email protected] [email protected], http://phya.yonsei.ac.kr/ ̃cskim/ [email protected]

A study of the use of fractals in top non-leptonic decays for the sake of discrimination against background is presented. Preliminary results show that fractals may provide a useful check for top event enrichment techniques.

In light of the recent experimental data from B factories, We try to explain the large branching ratio (compared to the Standard Model prediction) of the decay B → ηK in the context of R-parity violating (Rp / ) supersymmetry. We investigate other observed η modes and find that only two pairs of Rp / coupling can satisfy the requirements without affecting the other B → PP and B → V P decay mode...
