Query: Constraining the gauge and scalar sectors of the doublet left-right
  symmetric model   We consider a left-right symmetric extension of the Standard Model where the
spontaneous breakdown of the left-right symmetry is triggered by doublets. The
electroweak $\rho$ parameter is protected from large corrections in this
Doublet Left-Right Model (DLRM), contrary to the triplet case. This allows in
principle for more diverse patterns of symmetry breaking. We consider several
constraints on the gauge and scalar sectors of DLRM: the unitarity of
scattering processes involving gauge bosons with longitudinal polarisations,
the radiative corrections to the muon $\Delta r$ parameter and the electroweak
precision observables measured at the $Z$ pole and at low energies. Combining
these constraints within the frequentist CKMfitter approach, we see that the
fit pushes the scale of left-right symmetry breaking up to a few TeV, while
favouring an electroweak symmetry breaking triggered not only by the $ SU(2)_L
\times SU(2)_R $ bi-doublet, which is the case most commonly considered in the
literature, but also by the $ SU(2)_L $ doublet.
