Strange and charm quark contributions to the muon anomalous magnetic moment in lattice QCD with twisted-mass fermions / Extended Twisted Mass Collaboration (ETMC) Collaboration
We present a lattice calculation of the Hadronic Vacuum Polarization (HVP) contribution of the strange and charm quarks to the anomalous magnetic moment of the muon in isospin symmetric QCD. We employ the gauge configurations generated by the Extended Twisted Mass Collaboration (ETMC) with $N_f = 2 + 1 + 1$ flavors of Wilson-clover twisted-mass quarks at five lattice spacings and at values of the quark mass parameters that are close and/or include the isospin symmetric QCD point of interest.

We present a non-perturbative calculation of the form factors which contribute to the amplitudes for the radiative decays $P\to \ell \bar \nu_\ell \gamma$, where $P$ is a pseudoscalar meson and $\ell$ is a charged lepton. Together with the non-perturbative determination of the virtual photon corrections to the processes $P\to \ell \bar \nu_\ell$, this will allow accurate predictions to be made at $O(\alpha_{em})$ for leptonic decay rates for pseudoscalar mesons ranging from the pion to the $B$ meson.

An Investigation of New Methods for Numerical Stochastic Perturbation Theory in $\varphi^4$ Theory / Dalla Brida, Mattia (Milan Bicocca U. ; INFN, Milan Bicocca) ; Garofalo, Marco (U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Kennedy, A.D. (U. Edinburgh, Higgs Ctr. Theor. Phys.)
Numerical stochastic perturbation theory is a powerful tool for estimating high-order perturbative expansions in lattice field theory. The standard algorithms based on the Langevin equation, however, suffer from several limitations which in practice restrict the potential of this technique. [...]
