Analysis of the nonleptonic two-body decays of the hyperon

Mikhail A. Ivanov, Jürgen G. Körner, Valery E. Lyubovitskij +1

We systematically study two-body nonleptonic decays of light lambda hyperon with account for both short- and long-distance effects. The short-distance effects a…

Form-factor-independent test of lepton universality in semileptonic heavy meson and baryon decays

Stefan Groote, Mikhail A. Ivanov, Jürgen G. Körner +3

In the semileptonic decays of heavy mesons and baryons the lepton-mass dependence factors out in the quadratic coefficient of the differential distribution. We ca…

Polarization as an Additional Constraint on New Physics in the Transition

Mikhail A. Ivanov, Jürgen G. Körner, Pietro Santorelli +1

Measurements of the branching fractions of the semileptonic decays and systematically exceed the Standard Model (SM) predictions, pointi…

A new angle on an old problem: Helicity approach to neutron beta decay in the Standard Model

Stefan Groote, Jürgen G. Körner, Blaženka Melić

We elaborate on the dichotomy between the description of the semileptonic decays of heavy hadrons on the one hand and the semileptonic decays of light hadrons such as neutron d…

Coordinate space calculation of two- and three-loop sunrise-type diagrams, elliptic functions and truncated Bessel integral identities

S. Groote, J. G. Körner

We integrate three-loop sunrise-type vacuum diagrams in dimensions with four different masses using configuration space techniques. The finite parts of our results are in n…

Heavy quark pair production in gluon fusion at next-to-next-to-leading order: One-loop squared contributions

B. Kniehl, J. G. Körner, Z. Merebashvili +1

We calculate the next-to-next-to-leading order one-loop squared corrections to the production of heavy-quark pairs in the gluon-gluon fusion process. Together wit…
