form factors at large recoil: SCET analysis and a three-loop consistency check
Guido Bell, Philipp Böer, Thorsten Feldmann +2
The double-logarithmic series of non-relativistic form factors at large recoil is governed by a coupled set of integral equations, reflecting an intricate interplay…

form factors at large recoil: Interplay of soft-quark and soft-gluon dynamics
Guido Bell, Philipp Böer, Thorsten Feldmann +2
We perform an all-order analysis of double-logarithmic corrections to the so-called soft-overlap contribution to heavy-to-light transition form factors at large hadronic recoil. Sp…
