Updated determination of light-cone distribution amplitudes of octet baryons in lattice QCD
We present updated results for the wave function normalization constants and the first moments of the light-cone distribution amplitudes for the lowest-lying baryon octet. The analysis is carried out on a large number of n f = 2 + 1 lattice gauge ensembles, including ensembles at physical pion (and kaon) masses. These are spread across five different lattice spacings, enabling a controlled continuum limit. The main differences with respect to our earlier work [G. S. Bali (RQCD Collaboration), Light-cone distribution amplitudes of octet baryons from lattice QCD, .] are the use of two-loop conversion factors to an MS ¯ -like scheme and of an updated set of low-energy constants in the parametrization of the quark mass dependence. As a byproduct, for the first time, the anomalous dimensions for local leading-twist three-quark operators with one derivative are obtained.

Mellin moments of spin dependent and independent PDFs of the pion and rho meson
We compute the second moments of pion and rho parton distribution functions in lattice QCD with flavors of improved Wilson fermions. We determine both singlet and nonsinglet flavor combinations and, for the first time, take disconnected contributions fully into account. In the case of the rho, we also calculate the additional contribution arising from the structure function. The numerical analysis includes 26 ensembles, mainly generated by the CLS effort, with pion masses ranging from 420 down to 214 MeV and with 5 different lattice spacings in the range of 0.1 to 0.05 fm. This enables us to take the continuum limit, as well as to resolve the quark mass dependencies reliably. Additionally we discuss the contaminations of rho correlation functions by two-pion states.- 10 January 2022
