Beyond thresholds: reconstructing UV physics from IR expansions
Hiromasa Takaura, Wen Yin
We show that ultraviolet information can be extracted from low-energy expansion coefficients, assuming analyticity and the absence of massless singularities. By reorganizing the lo…
Gradient-flowed operator product expansion without IR renormalons
Martin Beneke, Hiromasa Takaura
A long-standing problem concerns the question how to consistently combine perturbative expansions in QCD with power corrections in the context of the operator product expansion (OP…
A new approach to quark mass determination using the gradient flow
Hiromasa Takaura, Robert V. Harlander, Fabian Lange
We propose a new method to determine quark masses using ratios of the vacuum-expectation values (VEVs) of flowed quark bilinear operators. They can be expressed as functions of the…
Determining the Quark Mass with the Gradient Flow
Hiromasa Takaura, Robert Harlander, Fabian Lange
We propose a new method to determine the quark mass by using bilinear operators of the flowed quark field defined within the gradient-flow formalism. This method enables the quark…
