On the analytic continuation and matching of threshold singularities from Vacuum Amplitudes
Selomit Ram\'ırez-Uribe, Prasanna K. Dhani, German F. R. Sborlini +1
We provide a detailed discussion for all kinematical configurations of the analytic continuation to negative values of initial-state on-shell energies used to generate interference…
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…
Vacuum amplitudes and time-like causal unitary in the loop-tree duality
The LTD Collaboration, Selomit Ramírez-Uribe, Andrés E. Rentería-Olivo +8
We present the first proof-of-concept application to decay processes at higher perturbative orders of LTD causal unitary, a novel methodology that exploits the causal properties of…
Rewording Theoretical Predictions at Colliders with Vacuum Amplitudes
Selomit Ramírez-Uribe, Prasanna K. Dhani, German F. R. Sborlini +1
We propose multiloop vacuum amplitudes as the optimal building blocks for efficiently assembling theoretical predictions at high-energy colliders. This hypothesis is strongly suppo…
Variational quantum eigensolver for causal loop Feynman diagrams and directed acyclic graphs
Giuseppe Clemente, Arianna Crippa, Karl Jansen +5
We present a variational quantum eigensolver (VQE) algorithm for the efficient bootstrapping of the causal representation of multiloop Feynman diagrams in the Loop-Tree Duality (LT…
From Causal Representation of Multiloop Scattering Amplitudes to Quantum Computing
Selomit Ramírez-Uribe
An overview of a quantum algorithm application for the identification of causal singular configurations of multiloop Feynman diagrams is presented. The quantum algorithm is impleme…
