Description
We propose a new method for quark mass determination utilizing the gradient flow. The matching of a ratio of flowed bilinear operators between the perturbative and lattice results determines the MSbar mass, potentially contributing to a more precise determination. In this talk, we present perturbative results at two loops: semianalytic expressions in the small- and large-m^2 t limits and numerical results over a wide range of m^2 t. We develop a new method to expand loop integrals in m^2 t or 1/(m^2 t), based on the Laplace transform.
