Description
We propose a new ``smeared'' operator product expansion (sOPE) in
which the set of local operators in the OPE are replaced by their locally smeared counterparts, generated by the gradient flow. The flow time, or smearing, parameter serves as a regulator for both Wilson coefficients and operator products. Matrix elements determined
nonperturbatively on the lattice using smeared degrees of freedom remain finite in the continuum limit, provided the physical smearing scale is kept fixed. We study the sOPE in scalar field theory and discuss the application to Deep Inelastic Scattering.
