abstract
We study left-right symmetric models which contain only fermion and gauge boson fields and no elementary scalars. The Higgs bosons are generated dynamically through a set of gauge- and parity-invariant 4-fermion operators. It is shown that in a model with a composite bi-doublet and two triplet scalars there is no parity breaking at low energies, whereas in the model with two doublets instead of two triplets parity is broken automatically regardless of the choice of the parameters of the model. For phenomenologically allowed values of the right-handed scale a tumbling symmetry breaking mechanism is realized in which parity breaking at a high scale $\mu_R$ propagates down and eventually causes the \EW symmetry breaking at the scale $\mu_{EW}\sim 100~GeV$. The model exhibits a number of low and intermediate mass Higgs bosons with certain relations between their masses. In particular, the components of the $SU(2)_L$ Higgs doublet $\chi_L$ are pseudo--\GBs of an accidental (approximate) $SU(4)$ symmetry of the Higgs potential and therefore are expected to be relatively light.

Calculations of cLFV cross sections in eμ scattering show the e−μ+ → W+W− channel at √s > 2MW offers better prospects for detecting heavy sterile neutrinos than the quartically suppressed e−μ+ → e+μ− process.
A proposed Chinese charm factory could detect heavy neutral leptons from axionlike-particle decays with a displaced-vertex search, reaching electron-neutrino mixing one to two orders of magnitude below current bounds.
PRISM multi-angle measurements in DUNE restore sensitivity to non-unitarity and sterile neutrinos in electron and muon sectors to levels achievable with small spectral uncertainties, with only marginal gains for tau neutrinos.
In the minimal pseudo-Dirac HNL scenario, light-neutrino oscillation data fixes an ellipse in the active flavour simplex for leading active-heavy interactions via a single complex amplitude and Majorana phase.
The FCC feasibility study describes how a staged electron-positron and hadron collider could deliver precision measurements on the Higgs, electroweak bosons, and top quark while searching for physics beyond the Standard Model.
