Numerical Stochastic Perturbation Theory in the Schrödinger Functional
Michele Brambilla, Mattia Dalla Brida, Francesco Di Renzo +2
The Schrödinger functional (SF) is a powerful and widely used tool for the treatment of a variety of problems in renormalization and related areas. Albeit offering many conceptual…
A one-loop study of matching conditions for static-light flavor currents
Dirk Hesse, Rainer Sommer
Heavy Quark Effective Theory (HQET) computations of semi-leptonic decays, e.g. B -> pi l nu, require the knowledge of the parameters in the effective theory for all components of t…
Matching of heavy-light flavour currents between HQET at order 1/m and QCD: I. Strategy and tree-level study
Michele Della Morte, Samantha Dooling, Jochen Heitger +2
We present a strategy how to match the full set of components of the heavy-light axial and vector currents in Heavy Quark Effective Theory (HQET), up to and including 1/m-correctio…
Numerical Stochastic Perturbation Theory and the Gradient Flow
Mattia Dalla Brida, Dirk Hesse
We study the Yang-Mills gradient flow using numerical stochastic perturbation theory. As an application of the method we consider the recently proposed gradient flow coupling in th…
HQET Flavor Currents Using Automated Lattice Perturbation Theory
Dirk Hesse
Matrix elements of heavy-light flavor currents play an important role in modern particle physics and precise theory predictions are of interest for phenomenology. Heavy Quark Effec…
