+ | <hidden TTP00-27 Light-Cone Distribution Functions for $B$ Decays at subleading Order in $1/m_b$ > We construct the higher twist structure functions that describe inclusive | ||

+ | b hadron decays in regions of phase space where the hadronic | ||

+ | decay products carry high energy but have low invariant mass. We show | ||

+ | that, for B meson decays, there are four new non-vanishing | ||

+ | matrix elements of non-local operators. We show that to subleading | ||

+ | twist these decays are parametrized in terms of four functions. We | ||

+ | compute the tree-level matching for a general heavy-to-light current | ||

+ | and apply it to B -> X_s gamma. Using a simple model for these | ||

+ | functions we estimate the subleading twist contributions to this | ||

+ | decay. | ||
