====== TTP00-27 Light-Cone Distribution Functions for $B$ Decays at subleading Order in $1/m_b$ ======
 
 
   <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.
