Flavor deconstruction refers to ultraviolet completions of the Standard Model where the gauge group is split into multiple factors under which fermions transform non-universally. We propose a mechanism for charging same-family fermions into different factors of a deconstructed gauge theory in a way that gauge anomalies are avoided. The mechanism relies in the inclusion of a strongly-coupled sector, responsible of both anomaly cancellation and the breaking of the non-universal gauge symmetry. As an application, we propose different flavor deconstructions of the Standard Model that, instead of complete families, uniquely identify specific third-family fermions. All these deconstructions allow for a new physics scale that can be as low as few TeV and provide an excellent starting point for the explanation of the Standard Model flavor hierarchies.

  1. Deconstructed Weak Isospin from a Symplectic Symmetry

    hep-ph 2026-03 conditional novelty 6.0 of 10

    An Sp(6) completion of deconstructed weak isospin predicts six new flavour-changing gauge bosons and pushes the intermediate SU(2)^3 breaking scale above ~550 TeV (or ~150 TeV at large scale separation) via K/D mixing...

  2. Probing Flavour Deconstruction via Primordial Gravitational Waves

    hep-ph 2025-09 conditional novelty 6.0 of 10

    Flavour deconstruction phase transitions can generate detectable gravitational waves, but their spectra typically peak above the millihertz range, making LISA detection possible yet not guaranteed.

  3. Flavour hierarchies, extended groups and composites

    hep-ph 2025-05 conditional novelty 2.0 of 10

    A composite Higgs model built on flavour-deconstructed gauge groups produces suppressed CKM and anarchic PMNS mixing as a consequence of the chosen fermion charge assignments.
