2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/43843We study the effects of supersymmetric contribution on both the B_d -> phi K^0 and B^\pm -> phi K^\pm modes using the perturbative QCD approach. We estimate the deviation of mixing-induced and direct CP asymmetries and discuss the strong-phase dependence of them.4 pages, 2 figures, to appear in the proceedings of the 12th International Conference on Supersymmetry and Unification of Fundamental Interactions (SUSY 2004), Tsukuba, Japan, June 17-23, 2004High Energy Physics - Phenomenologytext
