ASYMPTOTIC EXPANSIONS THROUGH THE LOOP-TREE DUALITY

Accurate theoretical predictions in the Standard Model (SM) are vital to disentangle possible new physics effects. The loop-tree duality (LTD) formalism transforms the integration domain of loop scattering amplitudes to a Euclidean space where asymptotic expansions of the integrand are well defined. The effectiveness of LTD for making asymptotic expansions has been shown in the large-mass and small-mass limits for Higgs production through gluon fusion. In this paper, we present a preliminary study aimed at generalising the method of asymptotic expansions in the LTD formalism. We use a toy amplitude and derive general guidelines.
