Three-particle di-light-cone distribution amplitudes of the -meson in heavy-quark effective theory
Riccardo Bartocci, Philipp Böer, Thorsten Feldmann +3
We present a systematic study of the three-particle di-light-cone distribution amplitudes (DLCDAs) of the -meson. They are defined through -meson--to--vacuum matrix elements…
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…
Subatomic Heroes
Anshika Bansal, Guido Bell, Aritra Biswas +44
Sharing the amazing achievements of the (particle) physics world with the general public is at the heart of the mission of the Subatomic Heroes, based at the University of Siegen,…
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…
Radiative tail of the three-particle light-cone distribution amplitudes for the baryon in HQET
Thorsten Feldmann, Daniel Vladimirov
We calculate the so-called radiative tail for the three-particle light-cone distribution amplitudes (LCDAs) of the baryon, following from the short-distance expansion of the…
