This book was released on 2004 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relative branching fractions of B{sub d, s}{sup 0} {yields} h{sup +}h'{sup -} decays (where h, h' = K or {pi}) and the direct Cp asymmetry A{sub CP} in the B{sub d}{sup 0} {yields} K{sup +}{pi}{sup -} mode are measured with 179 {+-} 11 pb {sup -1} of data collected using the CDF II detector at the Fermilab Tevatron p{bar p} collider. The first branching-fraction measurement of a B{sub s}{sup 0} meson to two pseudoscalars, {Beta}(B{sub s}{sup 0} {yields} K{sup +} K{sup -}), and a search for the baryon mode {Lambda}{sub b}{sup 0} {yields} p{sup +} h{sup -} are also presented, in addition to branching-fraction limits on the rare channels B{sub s}{sup 0} {yields} K{sup +} {pi}{sup -}, B{sub d}{sup 0} {yields} K{sup +}K{sup -}, and B{sub s}{sup 0} {yields} {pi}{sup +}{pi}{sup -}.
