From Lattice to the Lab: Illuminating Kaon Decays

24 Mar 2026, 08:00 → 25 Mar 2026, 20:00 Europe/Rome

Aula Salvini (Aula Salvini, Building 36, Laboratori Nazionali di Frascati (Rome), Italy)

Giuseppe Gagliardi (Istituto Nazionale di Fisica Nucleare), Silvia Martellotti (INFN - LNF), Federico Mescia (Istituto Nazionale di Fisica Nucleare), Matthew David Moulson (Istituto Nazionale di Fisica Nucleare), Francesco Sanfilippo (Istituto Nazionale di Fisica Nucleare), Gemma Maria Tinti (Istituto Nazionale di Fisica Nucleare)

This workshop aims to bring together theorists and experimentalists working on various aspects of kaon decays, with a focus on fostering interdisciplinary collaboration and advancing precision studies in flavor physics. Topics will include radiative kaon decays, rare processes, multi-lepton final states, and future prospects in K​ measurements. Special attention will be given to novel lattice QCD approaches and their phenomenological implications.  The program will feature a discussion session on Monte Carlo generators and radiative corrections, aimed at clarifying current methodologies and enhancing analysis tools. Contributions from major experimental collaborations—including NA62, KLOE/KLOE-2, E36, and LHCb—will be complemented by theoretical insights from lattice groups such as BMW, ETMC, RBC, and UKQCD.

This activity is part of the Theoretical Phenomenology Visiting Institute @ LNF, running from 23 March to 27 March 2026, and supported by CSN4 to promote the participation of early-career scientists. 

The workshop will take place in the Salvini Auditorium (Building 36, access via the LNF secondary entrance at Via E. Fermi, 60 – see map). 

Please access Zoom via the videoconference menu on the left-hand side.
