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…
Heavy Flavor Jet Substructure at Lepton Colliders
Prasanna K. Dhani, Oleh Fedkevych, Andrea Ghira
We provide a detailed analysis of event-shape observables, namely the energy correlation function and jet angularity, for heavy-flavor jets produced in electron-positron collisions…
Heavy Flavour Jet Substructure
Prasanna K. Dhani, Oleh Fedkevych, Andrea Ghira +2
We present a comprehensive study of energy correlation functions and jet angularities for heavy-flavour QCD jets. In particular, we discuss the possibility of using these observabl…
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…
