Graph theory-based automated quantum algorithm for efficient querying of acyclic and multiloop causal configurations
Salvador A. Ochoa-Oregon, Juan P. Uribe-RamÃrez, 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…
A Systematic Approach to Finite Multiloop Feynman Integrals
Prasanna K. Dhani, Konstantinos Pyretzidis, Selomit RamÃrez-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…
Catani's generalization of collinear factorization breaking
Leandro Cieri, Prasanna K. Dhani, Germán Rodrigo
We consider the most general form of soft and collinear factorization for hard-scattering amplitudes to all orders in perturbative Quantum Chromodynamics. Specifically, we present…
Quantum querying based on multicontrolled Toffoli gates for causal Feynman loop configurations and directed acyclic graphs
Selomit RamÃrez-Uribe, Andrés E. RenterÃa-Olivo, Germán Rodrigo
Quantum algorithms are a promising framework for unfolding the causal configurations of multiloop Feynman diagrams, which is equivalent to querying the \textit{directed acyclic gra…
Vacuum amplitudes and time-like causal unitary in the loop-tree duality
The LTD Collaboration, Selomit RamÃrez-Uribe, Andrés E. RenterÃa-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 RamÃrez-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…
