Loop Feynman integration on a quantum computer / de Lejarza, Jorge J. Martínez (Valencia U., IFIC) ; Cieri, Leandro (Valencia U., IFIC) ; Grossi, Michele (CERN) ; Vallecorsa, Sofia (CERN) ; Rodrigo, Germán (Valencia U., IFIC)
This work investigates in detail the performance and advantages of a new quantum Monte Carlo integrator, dubbed Quantum Fourier Iterative Amplitude Estimation (QFIAE), to numerically evaluate for the first time loop Feynman integrals in a near-term quantum computer and a quantum simulator. In order to achieve a quadratic speedup, QFIAE introduces a Quantum Neural Network (QNN) that efficiently decomposes the multidimensional integrand into its Fourier series. [...]

Quantum Computing for Data Analysis in High-Energy Physics / Delgado, Andrea (Oak Ridge) ; Hamilton, Kathleen E. (Oak Ridge) ; Date, Prasanna (Oak Ridge) ; Vlimant, Jean-Roch (Caltech) ; Magano, Duarte (Lisbon U.) ; Omar, Yasser (Lisbon U.) ; Bargassa, Pedrame (LIP, Lisbon) ; Francis, Anthony (NYCU, Hsinchu ; CERN) ; Gianelle, Alessio (INFN, Padua) ; Sestini, Lorenzo (INFN, Padua) et al.
Some of the biggest achievements of the modern era of particle physics, such as the discovery of the Higgs boson, have been made possible by the tremendous effort in building and operating large-scale experiments like the Large Hadron Collider or the Tevatron. [...]

Quantum Fourier Iterative Amplitude Estimation / de Lejarza, Jorge J. Martínez (Valencia U., IFIC) ; Grossi, Michele (CERN) ; Cieri, Leandro (Valencia U., IFIC) ; Rodrigo, Germán (Valencia U., IFIC)
Monte Carlo integration is a widely used numerical method for approximating integrals, which is often computationally expensive. In recent years, quantum computing has shown promise for speeding up Monte Carlo integration, and several quantum algorithms have been proposed to achieve this goal. [...]

Drell-Yan lepton-pair production: $q_T$ resummation at approximate N$^4$LL+N$^4$LO accuracy / Camarda, Stefano (CERN) ; Cieri, Leandro (Valencia U., IFIC) ; Ferrera, Giancarlo (Milan U.)
We consider Drell-Yan lepton pairs produced in hadronic collisions. We present high-accuracy QCD predictions for the transverse-momentum ($q_T$) distribution and fiducial cross sections in the small $q_T$ region. [...]

Fiducial perturbative power corrections within the q$_{\bf T}$ subtraction formalism / Camarda, Stefano (CERN) ; Cieri, Leandro (Valencia U., IFIC) ; Ferrera, Giancarlo (Milan U. ; INFN, Milan)
We consider higher-order QCD corrections to the production of high-mass systems in hadron collisions within the transverse-momentum (q$_{\rm T}$) subtraction formalism. We present a method to consistently remove the linear power corrections in q$_{\rm T}$ which appears when fiducial kinematical cuts are applied on the final state system. [...]

SO(3) family symmetry and axions / Reig, Mario (Valencia U., IFIC)
Motivated by the idea of Comprehensive Unification, we consider a gauged $SO(3)$ flavor extension of the Standard Model, including right-handed neutrinos and a Peccei-Quinn symmetry. The model accommodates the observed fermion masses and mixings and yields a characteristic, successful relation among them. [...]
