Description

Renormalized quark masses are fundamental parameters of the Standard Model, serving as critical inputs for theoretical predictions across a wide range of physics processes. In this work, we study Highly Improved Staggered Quark (HISQ) ensembles in the gradient flow lattice scheme. Using a small subset of our physical point ensembles, we compute flow-time-dependent renormalized quark masses using two methods. The first method is inspired by the Partially Conserved Axial Current (PCAC) relation, and the second method determines the mass renormalization factor. We then match the gradient flow quark masses to the $\overline{\mathrm{MS}}$ scheme. Our preliminary results provide guidance on the optimal flow and operator definitions for our upcoming production runs.
