A quantum representation of fragmentation functions through variational quantum circuits
David F. Rentería-Estrada, Roger J. Hernández-Pinto, Germán Rodrigo +2
We present a variational quantum-circuit model for fragmentation functions (FFs). Isospin and charge-conjugation symmetries are imposed to construct an independent six-flavor basis…
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…
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…
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…
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…
Towards higher-order collinear splittings with massive partons
Prasanna K. Dhani, Germán Rodrigo, German F. R. Sborlini
The singularities associated with QCD factorization in the collinear limit are key ingredients for high-precision theoretical predictions in particle physics. They govern the colli…
Triple-collinear splittings with massive particles
Prasanna K. Dhani, Germán Rodrigo, German F. R. Sborlini
We analyze in detail the most singular behaviour of processes involving triple-collinear splittings with massive particles in the quasi-collinear limit, and present compact express…
