ZN×ZM Flavour Symmetry

Abstract

The ZN×ZM symmetry is a novel flavour symmetry, that can provide an explanation to the flavour structure of the Standard Model through the Froggatt-Nielsen mechanism. We have investigated the flavour bounds on the minimal Z2×Z5, and a non-minimal Z2×Z9 version of this symmetry using the current quark and lepton flavour physics data as well as the future projected sensitivities of the quark and lepton flavour effects. It turns out that the future high-luminosity phase-I and II of the LHCb are going to play a crucial role in constraining the parameters of the minimal and the non-minimal Z2×ZN flavour symmetries. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
