Three Parton Corrections in $B\to PP$ decays
Abstract
Description
The $1/m_b$ corrections from the three parton $q\bar{q}g$ Fock state of the final state light meson in $B\to PP$ decays are evaluated by means of a collinear expansion method. The impacts of these corrections on the $CP$ averaged branching ratios of the $B\to πK$ decays are analyzed.
