Study of rare b decays with the DELPHI detector at LEP

Abstract:

Rare decays of beauty particles were studied in several charmless modes using the data collected with the DELPHI detector at LEP from t991 to 1994. These decays are mediated by both tree level b → u and one-loop penguin b → s, d transitions. Evidence for charmless decays was obtained in two body hadronic modes. The branching ratios of 30a,s to π+π- or K+π- and B -u to p0π- or K*0π- were found to be (2.8+1.5-1.0 ± 0.2) × 10-5 and (1.7 +1.2-0.8 ± 0.2) × 10-4 respectively. The fraciion of these ...
