In this talk, we present the first fully non-perturbative computation of the decay rate of $D_s\to X\ell\nu$ and of the associated leptonic moments, carried out on state-of-the-art ETMC ensembles at the physical point with four lattice spacings and three volumes. The extraction of the relevant smeared spectral densities from Euclidean four-point correlation functions has been performed with...

We present results for the nucleon axial, scalar, and tensor charges, as well as the nucleon $\sigma$-terms, using four twisted mass fermion ensembles at four lattice spacings, including one at a finer lattice spacing of $\sim 0.05$ fm. The masses of the degenerate up and down, strange, and charm quarks are tuned to approximately their physical values. We compute both isovector and isoscalar...

We present the full decomposition of the momentum and spin fractions carried by quarks and gluons in the nucleon. We employ three gauge ensembles generated with Nf=2+1+1 Wilson twisted-mass clover-improved fermions at the physical quark masses. It allows us to determine for the first time the momentum and spin decompositions at the continuum limit with the extrapolation directly performed at...

We present the results for the electromagnetic form factors of the proton and neutron using three ensembles of twisted mass fermions at the physical point. Studying the momentum transfer dependence of the form factors resulting from a multi-state fitting procedure, we obtain the electric and magnetic radii and the magnetic moments in the continuum limit. Furthermore, we extend the analysis to...

We present a lattice calculation of the Hadronic Light by Light (HLbL) contribution of the strange- and charm-quark connected contributions to the anomalous magnetic moment of the muon. 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 four lattice spacings at the physical point....

An update on the ongoing effort to compute QED corrections to isoQCD observables. We will discuss the general computational strategy, focusing on the scale setting and the observables proposed in the November proposal. Finally, we will give a brief update on the baryon-splitting program we already started.

We present a lattice QCD calculation of the unpolarized transverse-momentum dependent parton distribution function (TMD PDF) of the nucleon using Large Momentum Effective Field Theory. The calculation is based on the evaluation of three key ingredients entering the TMD factorization formula: the quasi-TMD PDF, the Collins–Soper kernel, and the reduced soft function. We employ three $N_f=2+1+1$...

Preliminary results are presented for a novel formulation of the overlap Dirac operator in lattice QCD that employs the diagonal Kenney-Laub (KL) iterates to approximate the matrix sign function. KL iterates require no information about the spectrum of the kernel operator and, when expressed via their partial fraction decomposition, offer a practical alternative for approximating the matrix...
