Description
Left-Right Symmetric Models (LRSM) attempt at giving an understanding of the violation of parity (or charge-conjugation) by the weak interactions in the SM through the introduction of right-handed currents. The spontaneous symmetry breaking of SU(2)_LxSU(2)_RxU(1)_(B-L) is usually triggered by an enlarged Higgs sector, usually consisting of two triplet fields (left-right symmetry breaking) and a bi-doublet (electroweak symmetry breaking). I reconsider an alternative LRSM with doublet instead of triplet fields and a Higgs bi-doublet. After explaining some features of this model, I discuss constraints on its parameters using electroweak precision and neutral-meson mixing observables, combining them using the CKMfitter frequentist statistical framework.
