Exploratory calculation of the rare hyperon decay Σ+ → pℓ + ℓ − from lattice QCD
Abstract The rare hyperon decay Σ+ → pℓ + ℓ − is a flavour-changing neutral current process mediated by an s → d transition that occurs only at loop level within the Standard Model. Consequently, this decay is highly suppressed, making it a promising avenue for probing potential new physics. While p...
