Light-cone sum rules in soft-collinear effective theory
We derive light-cone sum rules (LCSRs) for exclusive B-meson decays into light energetic hadrons from correlation functions within soft-collinear effective theory (SCET). In these sum rules the short-distance scale refers to "hard-collinear" interactions with virtualities of order (Lambda_...
