Method for Flavor Tagging in Neutral B Meson Decays

Abstract

A method is proposed for tagging the flavor of neutral $B$ mesons in the study of CP-violating decay asymmetries. The method makes use of a possible difference in interactions in $B\pi$ or $B^{\ast }\pi$ systems with isospins 1/2 and 3/2, and would be particularly clean if the $I=1/2$ systems can be detected as ``$B^{\ast \ast }$'' resonances.
