Mathematical aspects of the scattering amplitude for $H\to gg$ within the loop-tree duality
June 10, 2020
In this talk, we study the decay width of $H\to gg$ at next-to-leading order in the large top quark mass effective limit.
We follow the ideas of the four-dimensional-unsubtraction method, in which a carefully study of
infrared and ultraviolet singularities is carried out. In fact, the cancellation of these singularities
is performed at integrand level.

very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
