Higher twist corrections to -meson decays into a proton and dark antibaryon from QCD light-cone sum rules
Anastasia Boushmelev, Marcel Wald
The -Mesogenesis framework anticipates decays of mesons into a dark antibaryon and various Standard Model baryons. Here, we focus on the exclusive decay process $B\to p…

Automation of Beam and Jet functions at NNLO
Guido Bell, Kevin Brune, Goutam Das +1
We present a novel framework to streamline the calculation of jet and beam functions to next-to-next-to-leading order (NNLO) in perturbation theory. By exploiting the infrared beha…

QCD sum rules for parameters of the -meson distribution amplitudes
Muslem Rahimi, Marcel Wald
We obtain new estimates for the parameters , and their ratio , which appear in the second moments of the -meson light-cone distribu…
