Hadronization of b ---> c anti-c s

Abstract

Abstract The b → c c s transition is usually believed to hadronize predominantly in B → X c D s (∗)− with the D s (∗)− originating from the virtual W . We demonstrate in a variety of independent ways that other hadronization processes cannot be neglected. The invariant mass of c s has sizable phase-space beyond m d + m k . The rate for B → D D K X could be significant and should not be ignored as was done in previous experimental analyses. We estimate the number of charmed hadrons per B -decay, n c , to be ≈ 1.3 to higher accuracy than obtained in previous investigations. Even though n c is currently measured to be about 1.1, observing a significant B → D D K X would support n c ≈ 1.3. Many testable consequences result, some of which we discuss.
