Pseudoscalar transition form factors and the hadronic light-by-light contribution to the muon $g-2$

Antoine Gérardin, Jana N. Guenther, Lukas Varnhorst +1

We present preliminary results from our calculation of the pseudoscalar transition form factors of the $\eta$ and ${\eta }^{\prime }$ mesons using staggered quarks on $N_f=2+1+1$ gauge ensembles gen…
