Citation: K. Nakamura et al. (Particle Data Group), JP G 37 , 075021 (2010) (URL: http://pdg.lbl.gov) BOTTOM MESONS BOTTOM MESONS ( B = ± 1) ( B = 1) B + = u b , B 0 = d b , B 0 = db , B = ub , similarly for B ’s B -particle organization B -particle organization Many measurements of B decays involve admixtures of B hadrons. Pre- viously we arbitrarily included such admixtures in the B ± section, but be- cause of their importance we have created two new sections: “ B ± / B 0 Admixture” for Υ (4 S )resu ltsand“ B ± / B 0 / B 0 s / b -baryon Admixture” for results at higher energies. Most inclusive decay branching fractions and χ b at high energy are found in the Admixture sections. B 0 - B 0 mixing data are found in the B 0 section, while B 0 s - B 0 s mixing data and B - B mix- ing data for a B 0 / B 0 s admixture are found in the B 0 s section. CP -violation data are found in the B ± , B 0 ,and B ± B 0 Admixture sections. b -baryons are found near the end of the Baryon section. The organization of the B sections is now as follows, where bullets indi- cate particle sections and brackets indicate reviews. B ± mass, mean life, CP violation, branching fractions B 0 mass, mean life, B 0 - B 0 mixing, CP violation, branching fractions B ± B 0 Admixtures CP violation, branching fractions B ± / B 0 / B 0 s / b -baryon Admixtures mean life, production fractions, branching fractions B mass B 1 (5721) 0 mass B 2 (5747) 0 mass B 0 s HTTP://PDG.LBL.GOV Page 1 Created: 10/15/2010 14:48
