NNLO beam functions for angularity distributions

Guido Bell, Kevin Brune, Goutam Das +1

The popular class of angularity event shapes provides a wealth of information on the hadronic final-state distribution in collider events. While initially proposed for co…

The NNLO gluon beam function for jet-veto resummation

Guido Bell, Kevin Brune, Goutam Das +2

We compute the gluon beam function for jet-veto resummation to next-to-next-to-leading order (NNLO) in the strong-coupling expansion. Our calculation is based on an automated frame…

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…

Automated Calculation of Beam Functions at NNLO

Guido Bell, Kevin Brune, Goutam Das +1

We present an automated framework for the calculation of beam functions that describe collinear initial-state radiation at hadron colliders at next-to-next-to leading order (NNLO)…

The NNLO quark beam function for jet-veto resummation

Guido Bell, Kevin Brune, Goutam Das +1

We consider the quark beam function that describes collinear initial-state radiation that is constrained by a veto on reconstructed jets. As the veto is imposed on the transverse m…

-meson decay into a proton and dark antibaryon from QCD light-cone sum rules

Alexander Khodjamirian, Marcel Wald

The recently developed -Mesogenesis scenario predicts decays of mesons into a baryon and hypothetical dark antibaryon . We suggest a method to calculate the amplitude of…

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…
