Angular Observables In Semileptonic B-meson Decays

Abstract

In I,his dissertation , we reviewed the weak decays of B-mesolls, B --t 1(1/ nnd Br. -4 D(D*)lt tlsiug heiicil,y formalism. \o\' ithoul, relying all t he impulse a pp rOx ilJlaLioll , the form factors for thel:ic two fold and four fold decays were calculated usillg reiat,jvi!ltic qua rk modelllnd we willus<' t hem ill ollr analysis. T he form factors and thl! difff'I'Pot,iai decay rates for these cxclusiyc decays depend on the sqllllrc of moment.um tra nsfer ((l). In terms of hclicity amplitudes t hat take into accou nt t he lepton mnss crrccts, we ca lculate a four-fold angular decay distribution for the B --t DOll. The rcsults will be compared with the findings available ill the literature.
