Measurements of the branching fractions and CP asymmetries of B-+/- -> J/psi pi(+/-) and B-+/- -> psi(2S)pi(+/-) decays

Measurements of the branching fractions and CP asymmetries of B-+/- -> J/psi pi(+/-) and B-+/- -> psi(2S)pi(+/-) decays

A study of B ±→J/ψπ ± and B ±→ψ(2S)π ± decays is performed with data corresponding to 0.37fb -1 of proton-proton collisions at √s=7TeV. Their branching fractions are found to be B(B ±→J/ψπ ±)=(3.88±0. 11±0.15)×10 -5andB(B ±→ψ(2S) π ±)=(2.52±0.26±0.15)×10 -5,where the first uncertainty is related to...
