Lattice calculation of the $\pi^0$, $\eta$ and $\eta^{\prime}$ transition form factors and the hadronic light-by-light contribution to the muon $g-2$

Autor: Gérardin, Antoine, Verplanke, Willem E. A., Wang, Gen, Fodor, Zoltan, Guenther, Jana N., Lellouch, Laurent, Szabo, Kalman K., Varnhorst, Lukas

In this paper we present a first ab-initio calculation of the $\pi^0$, $\eta$ and $\eta^{\prime}$ transition form factors performed with physical light-quark masses. We provide a complete parametrization of the form factors that includes both single

A model for NL and SL decays by $\overline{B}^0 \to D^{**}$ transitions with $BR(j=1/2) \ll BR(j=3/2)$ using the $LLSW$ scheme

Autor: Le Yaouanc, Alain, Leroy, Jean-Pierre, Roudeau, Patrick

We present a model for the vector and axial form factors of the transitions $\overline{B}^0 \to D^{**}$ in good agreement with the presently available data and based on the present theoretical knowledge, combining a) the safe lattice QCD predictions

In the Wick-Cutkosky model, where two scalar massive constituents interact by means of the exchange of a scalar massless particle, the Bethe-Salpeter equation has solutions of two types, called "normal" and "abnormal". In the non-relativistic limit,
