Improved Measurements of the Branching Fractions for B0 into pi+pi- and B0 into K+pi-, and a Search for B0 into K+K-
The authors present measurements of the branching fractions for the charmless two-body decays B{sup 0} {yields} {pi}{sup +}{pi}{sup -} and B{sup 0} {yields} K{sup +}{pi}{sup -}, and a search for the decay B{sup 0} {yields} K{sup +}K{sup -}. They include the effects of final-state radiation from the daughter mesons for the first time, and quote branching fractions for the inclusive processes B{sup 0} {yields} h{sup +}h'{sup -}n{gamma}, where h and h' are pion or kaons. The maximum value of the sum of the energies of the n undetected photons, E{sub {gamma}}{sup max}, is mode-dependent. Using a data sample of approximately 227 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC.
