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…
A perturbative framework to probe infrared sensitivity in non-Abelian gauge theories
Duarte Fontes, Dennis Horstmann, Kirill Melnikov +1
Understanding the infrared sensitivity of perturbative predictions in QCD is important for assessing the magnitude of possible non-perturbative power corrections to processes with…
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…
Integral of the double-emission eikonal function for a massive and a massless emitter at an arbitrary angle
Dennis Horstmann, Kirill Melnikov, Ming-Ming Long +1
We present an analytic calculation of the integrated double-emission eikonal function of a massive and a massless emitter whose momenta are at an arbitrary angle to each other. Thi…
