Charged pion electric polarizability from lattice QCD
Hossein Niyazi, Andrei Alexandru, Frank X. Lee +1
We present a calculation of the charged pion electric polarizability using the background field method. To extract the mass-shift induced by the electric field for the accelerated…

Setting the scale for nHYP fermions with the Lüscher-Weisz gauge action
Hossein Niyazi, Andrei Alexandru, Frank X. Lee +1
Lattice QCD calculations using gauge smearing for fermion kernels are computationally efficient. Hypercubic blocking (nHYP smearing) has been shown to reduce scaling errors. In thi…
