Description
The loop-tree duality (LTD) has become a novelty
alternative to bootstrap the numerical evaluation of
multi-loop scattering amplitudes.
It has indeed been found that Feynman integrands,
after the application of LTD, displays a representation
containing only physical information, the so-called
causal representation.
In this talk, I discuss the all causal representation
of multi-loop Feynman integrands, recently found in terms
of features that describe a loop topology, cusps,
and edges.
Likewise, in order to elucidate the numerical stability
in the LTD integrands, we present applications that
involve the numerical evaluation of four-loop integrals
with the presence of several kinematic invariants.
