We use the mass insertion approximation method generalized by including the possibility of a light right-stop. We find that the dominant effect is given by the contributions of the mass insertions deltaU_LL(32) and deltaU_RL(32) to the Wilson coefficient of the chromomagnetic operator. By considering both these contributions simultaneously, the CP asymmetry in B -> Phi K(S) process is significantly reduced and negative values, which are within the 1-sigma experimental range and satisfy the b -> s gamma constraints, can be obtained.", "revisions": [ { "version": "v1", "updated": "2003-06-09T19:00:04.000Z" } ], "analyses": { "subjects": [ "12.60.Jv", "14.80.Ly", "13.25.Hw" ], "keywords": [ "cp asymmetry", "chargino contributions", "mass insertion approximation method", "model independent analysis" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
