Understanding IR singularities in the Loop-Tree Duality
Germán Rodrigo, Leandro Cieri, Prasanna K. Dhani +11
One of the main advantages of the Loop-Tree Duality representation of scattering amplitudes is that it makes the origin of infrared and threshold singularities particularly transpa…

A Systematic Approach to Finite Multiloop Feynman Integrals
Prasanna K. Dhani, Konstantinos Pyretzidis, Selomit Ramírez-Uribe +4
Finite Feynman integrals have been advocated as the optimal components for constructing a basis of master integrals in multiloop calculations, due to their improved analytic and nu…

Local renormalisation from causal loop-tree duality
German Sborlini, Jose Rios-Sanchez
We report recent progress on the development of a local renormalisation formalism based on causal loop-tree duality (cLTD). By performing an expansion around the UV-propagator in a…
