Twin Pati-Salam theory of flavour with a TeV scale vector leptoquark

Abstract We propose a twin Pati-Salam (PS) theory of flavour broken to the G 4321 gauge group at high energies, then to the Standard Model at low energies, yielding a TeV scale vector leptoquark U 1 μ $$ {U}_1^{\mu } $$ (3, 1, 2/3) which has been suggested to address the lepton universality anomalie...
