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…
Gauge theory approach to describe ice crystals habit evolution in ice clouds
Gianluca Di Natale, Francesco Pio De Cosmo, Leandro Cieri
Ice clouds, particularly cirrus clouds, significantly influence Earth's radiative balance but remain poorly characterized in current climate models. A major uncertainty arises from…
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…
Loop Feynman integration on a quantum computer
Jorge J. MartÃnez de Lejarza, Leandro Cieri, Michele Grossi +2
This work investigates in detail the performance and advantages of a new quantum Monte Carlo integrator, dubbed Quantum Fourier Iterative Amplitude Estimation (QFIAE), to numerical…
