In a recent work arXiv:2008.08601, Halverson, Maiti and Stoner proposed a description of neural networks in terms of a Wilsonian effective field theory. The infinite-width limit is mapped to a free field theory, while finite $N$ corrections are taken

Nucleon axial, scalar, and tensor charges using lattice QCD at the physical pion mass

Autor: Hasan, Nesreen, Green, Jeremy, Meinel, Stefan, Engelhardt, Michael, Krieg, Stefan, Negele, John, Pochinsky, Andrew, Syritsyn, Sergey

We report on lattice QCD calculations of the nucleon isovector axial, scalar, and tensor charges. Our calculations are performed on two 2+1-flavor ensembles generated using a 2-HEX-smeared Wilson-clover action at the physical pion mass and lattice sp
