SCET sum rules for B → P and B → V transition form factors
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 nonfactorizable contributions at leading power in the Λ/mb expansion and to first order in the strong coupling constant αs, neglecti...
متن کامل8 Analysis of the B → a 1 ( 1260 ) form - factors with light - cone QCD sum rules
In this article, we calculate the B → a1(1260) form-factors V1(q 2), V2(q 2), V3(q 2) and A(q2) with the B-meson light-cone QCD sum rules. Those formfactors are basic parameters in studying the exclusive non-leptonic two-body decays B → AP and semi-leptonic decays B → Alνl, B → Al̄l. Our numerical results are consistent with the values from the (light-cone) QCD sum rules. The main uncertainty co...

متن کاملB → π and B → K Transitions from QCD Sum Rules on the Light - Cone Patricia
FERMILAB–PUB–98/067–T (extended version) CERN–TH/98–215 hep-ph/9802394 Abstract: I calculate the form factors describing semileptonic and penguin-induced decays of B mesons into light pseudoscalar mesons. The form factors are calculated from QCD sum rules on the light-cone including contributions up to twist 4, radiative corrections to the leading twist contribution and SU(3)-breaking effects. ...
متن کاملThe B π form factor from light-cone sum rules in soft-collinear effective theory
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 [1]. In these sum rules the short-distance scale refers to “hard-collinear” interactions with virtualities of order ΛQCDmb. Hard scales (related to virtualities of order mb) are integrated out and enter via external coefficien...
