Isovector charges of the nucleon from 2+1-flavor QCD with clover fermions
Boram Yoon, Yong-Chull Jang, Rajan Gupta +8
We present high-statistics estimates of the isovector charges of the nucleon from four 2+1-flavor ensembles generated using Wilson-clover fermions with stout smearing and tree-leve…
Axial-Current Matrix Elements in Light Nuclei from Lattice QCD
Martin J. Savage, Phiala E. Shanahan, Brian C. Tiburzi +7
I present results from the first lattice QCD calculations of axial-current matrix elements in light nuclei, performed by the NPLQCD collaboration. Precision calculations of these m…
Proton-proton fusion and tritium -decay from lattice quantum chromodynamics
Martin J. Savage, Phiala E. Shanahan, Brian C. Tiburzi +7
The nuclear matrix element determining the fusion cross section and the Gamow-Teller matrix element contributing to tritium -decay are calculated with lattice Qu…
Controlling Excited-State Contamination in Nucleon Matrix Elements
Boram Yoon, Rajan Gupta, Tanmoy Bhattacharya +10
We present a detailed analysis of methods to reduce statistical errors and excited-state contamination in the calculation of matrix elements of quark bilinear operators in nucleon…
