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 nf 1/4 2 & thorn; 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 et al. (RQCD Collaboration), Light-cone distribution amplitudes of octet baryons from lattice QCD, Eur. Phys. J. A 55, 116 (2019).] 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.
