New Quarkonium Results from the BABAR experiment

Abstract

New BABAR results on B mesons and quarkonia are presented: an analysis of B{sup +} {yields} X(3872)K{sup +} and B{sup 0} {yields} X(3872)K{sup 0} decays with X(3872) {yields} J/{psi}{pi}{sup +}{pi}{sup -}, a precise measurement of the B mass difference {Delta}m{sub B} = m(B{sup 0}) -m(B{sup +}) and a study of hadronic transition between {Upsilon} mesons
