Vector-Like Leptons in Light of the Cabibbo-Angle Anomaly

This chapter presents the extension of the gauge theory model of the weak interaction to describe the weak interaction decays of quarks. It introduces the Cabibbo angle and the more general scheme of CKM mixing. It describes the realization of parity, CP, and time reversal symmetries in a general theory of quark mixing. Finally, it pulls all of the strands of previous chapters together to write the full set of equations of the Standard Model of particle physics.

Existing Data

Electromagnetic fields in the interior of the nucleus (hypernucleus) as well as inside the constituent nucleons (hyperons) are calculated. The results are discussed in the context of the Salam–Strathdee phase transition in connection with the possible vanishing of the Cabibbo angle. We show that existing data constrain the minimal range of 'normal' values for the invariant [Formula: see text] to be [Formula: see text]. Interestingly, in many Λ-hypernuclei [Formula: see text] is outside this minimal range.
