Heavy Quark Fragmentation Functions In The Heavy Quark Effective Theory

Abstract

We calculate fragmentation functions for a b-quark to fragment into color-singlet P-wave bound states $\bar{c}b$ in the Heavy Quark Effective Theory with the exact account of $O(1/m_b)$ corrections. We demonstrate an agreement of the obtained results with the corresponding calculations carried out in quantum chromodynamics.
