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…
Towards multiloop local renormalization within Causal Loop-Tree Duality
Jose Rios-Sanchez, German Sborlini
Renormalization is a well-known technique to get rid of ultraviolet (UV) singularities. When relying on Dimensional Regularization (DREG), these become manifest as -poles, allow…
