*CANCELLED* Lattice QCD calculation of the nucleon axial coupling $g_A$

The nucleon axial coupling $g_A$ controls the rate of neutron beta decay and the strength of the nucleon-nucleon force that binds nuclei together, and therefore plays an important role in a wide range of physical phenomena.  From the structure of the proton and nuclei to the rate of neutrino emission from stars, $g_A$ is ubiquitous in nuclear physics.  Though known experimentally to incredibly high precision (less than 0.2\%) its successful calculation from first principles has been elusive.  The calculation of $g_A$ from lattice QCD is considered by many a prerequisite to demonstrate the ability of lattice QCD to play a role in nuclear physics analogous to the role it has played in particle physics over the past, say, 20 years.  I will discuss a recently completed calculation, with the CalLat collaboration, of $g_A$ to an unprecedented precision of 1\%.  The calculation, which utilizes DWF valence quarks on the HISQ four flavor ensembles, achieves high precision thanks to a new computational strategy, which I will highlight.
