Abstract

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.

MEASUREMENTS OF BRANCHING FRACTIONS AND CP VIOLATING ASYMMETRIES IN B0 ---> PI+ PI-, K+ PI-, K+ K- DECAYS

Technical Report Farbin, Amir

We present measurements of branching fractions and CP-violating asymmetries for neutral B meson decays to two-body final states of charged pions and kaons. The results are obtained from a data sample of about 88 million {Upsilon}(4S) {yields} B{bar B} decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-independent fit we measure the charge-averaged branching fractions {Beta}(B{sup 0} {yields} {pi}{sup +} {pi}{sup -}) = (4.7 {+-} 0.6 {+-} 0.2) x 10{sup -6} and {Beta}(B{sup 0} {yields} K{sup +}{pi}{sup -}) = (17.9 {+-} 0.9 {+-} 0.7) x 10{sup -6}, wheremore »« less

Journal Article Aubert, B ; Bona, M ; Boutigny, D ; ... - Physical Review. D, Particles Fields

Branching fraction measurements of charmless B{sup 0}{yields}K*{sup 0}h{sub 1}{sup +}h{sub 2}{sup -} (h{sub 1,2}=K, {pi}) decays are presented, using a data sample of 383x10{sup 6} {upsilon}(4S){yields}BB decays collected with the BABAR detector at the PEP-II asymmetric-energy B-meson factory at SLAC. The results are B(B{sup 0}{yields}K*{sup 0}K{sup +}K{sup -})=(27.5{+-}1.3{+-}2.2)x10{sup -6}, B(B{sup 0}{yields}K*{sup 0}{pi}{sup +}K{sup -})=(4.6{+-}1.1{+-}0.8)x10{sup -6}, and B(B{sup 0}{yields}K*{sup 0}{pi}{sup +}{pi}{sup -})=(54.5{+-}2.9{+-}4.3)x10{sup -6}. The first errors quoted are statistical and the second are systematic. An upper limit is set for B(B{sup 0}{yields}K*{sup 0}K{sup +}{pi}{sup -})<2.2x10{sup -6} at 90% confidence level. We also present measurements of CP-violating asymmetries for the observed decays.

Branching fraction and asymmetry measurements of charmless B{sup +}{yields}K*{sup +}h{sub 1}{sup +}h{sub 2}{sup -} (where h{sub 1,2}=K, {pi}) decays are presented, using a data sample of 232x10{sup 6} {upsilon}(4S){yields}BB decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. Using a maximum likelihood fit, the following branching fraction results were obtained: B(B{sup +}{yields}K*{sup +}K{sup +}K{sup -})=(36.2{+-}3.3{+-}3.6)x10{sup -6} and B(B{sup +}{yields}K*{sup +}{pi}{sup +}{pi}{sup -})=(75.3{+-}6.0{+-}8.1)x10{sup -6}.
