Lattice QCD calculation of the pion distribution amplitude with domain wall fermions at physical pion mass Open
We present a direct lattice QCD calculation of the x-dependence of the pion distribution amplitude (DA), which is performed using the quasi-DA in large momentum effective theory on a domain-wall fermion ensemble at physical quark masses an…

A cosmic microwave background search for fine-structure constant evolution Open
In some extensions of the standard model of particle physics, the values of the fundamental coupling constants vary in space and time. Some observations of quasars hint at time and spatial variation of the fine structure constant $α$. Here…
