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…
Graph theory-based automated quantum algorithm for efficient querying of acyclic and multiloop causal configurations
Salvador A. Ochoa-Oregon, Juan P. Uribe-Ramírez, Roger J. Hernández-Pinto +2
Quantum algorithms provide a promising framework in high-energy physics, in particular, for unraveling the causal configurations of multiloop Feynman diagrams by identifying Feynma…
