The $B \to \pi$ form factor from light-cone sum rules in soft-collinear effective theory / Hurth, Tobias (CERN ; SLAC) ; De Fazio, Fulvia (INFN, Bari) ; Feldmann, Thorsten (Siegen U.)
Recently, we have derived light-cone sum rules for exclusive B-meson decays into light energetic hadrons from correlation functions within soft-collinear effective theory. In these sum rules the short-distance scale refers to ``hard-collinear'' interactions with virtualities of order \Lambda_{QCD} m_b. [...]

Light-cone sum rules in soft-collinear effective theory / De Fazio, F (INFN, Bari) ; Feldmann, T (Siegen U.) ; Hurth, Tobias (CERN ; SLAC)
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_{QCD}*m_b). [...]

Light-cone sum rules: A SCET-based formulation / De Fazio, F (INFN, Bari, Italy) ; Feldmann, T (Univ. Siegen, Germany) ; Hurth, Tobias (CERN)
We describe the construction of light-cone sum rules (LCSRs) for exclusive $B$-meson decays into light energetic hadrons from correlation functions within soft-collinear effective theory (SCET). As an example, we consider the SCET sum rule for the $B \to \pi$ transition form factor at large recoil, including radiative corrections from hard-collinear loop diagrams at first order in the strong coupling constant..

Factorization of heavy-to-light form factors in soft-collinear effective theory / Beneke, M. (Aachen, Tech. Hochsch.) ; Feldmann, T. (CERN)
Heavy-to-light transition form factors at large recoil energy of the light meson have been conjectured to obey a factorization formula, where the set of form factors is reduced to a smaller number of universal form factors up to hard-scattering corrections. In this paper we extend our previous investigation of heavy-to-light currents in soft-collinear effective theory to final states with invariant mass Lambda^2 as is appropriate to exclusive B meson decays.

SCET sum rules for B->P and B->V transition form factors / De Fazio, F (INFN Bari, Italy) ; Feldmann, T (Univ. Siegen, Germany) ; Hurth, Tobias (CERN ; SLAC)
We investigate sum rules for heavy-to-light transition form factors at large recoil derived from correlation functions with interpolating currents for light pseudoscalar or vector fields in soft-collinear effective theory (SCET). We consider both, factorizable and non-factorizable contributions at leading power in the Lambda/m_b expansion and to first order in the strong coupling constant alpha_s, neglecting contributions from 3-particle distribution amplitudes in the B-meson.

Factorization, the light-cone distribution amplitude of the B-meson and the radiative decay $B \to \gamma l \nu_{l}$ / Descotes-Genon, S ; Sachrajda, Christopher T C
We study the radiative decay B -> gamma l nu_l in the framework of QCD factorization. We demonstrate explicitly that, in the heavy-quark limit and at one-loop order in perturbation theory, the amplitude does factorize, i.e. [...]

Spectator interactions and factorization in $B \to \pi ell \nu$ decay / Beneke, M. (Aachen, Tech. Hochsch.) ; Feldmann, T. (CERN)
We investigate the factorization of different momentum modes that appear in matrix elements for exclusive B meson decays into light energetic particles for the specific case of B -> pi form factors at large pion recoil. We first integrate out hard modes with virtualities of order m_b^2 (m_b being the heavy quark mass), and then hard-collinear modes with virtualities m_b Lambda (Lambda being the strong interaction scale).
