 +   <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.
