Experiments in progress may confirm a nonzero neutrinoless double beta decay rate in conflict with the cosmological upper limit on neutrino masses and thus require new physics beyond the Standard Model. A natural candidate is the Left-Right symmetric theory, which led originally to neutrino mass and the seesaw mechanism. In the absence of cancelations of large Dirac Yukawa couplings, we show how such a scenario would require a low scale of Left-Right symmetry breaking roughly below 10 TeV, tantalizingly close to the LHC reach.

  1. Loop-Level Lepton Flavor Violation and Diphoton Signals in the Minimal Left-Right Symmetric Model

    hep-ph 2025-12 conditional novelty 6.0 of 10

    Recasting axion limits onto the one-loop H3 couplings of the minimal left-right symmetric model excludes the right-handed scale up to 2×10^9 GeV and could eventually probe 6×10^11 GeV.

  2. Probing sterile neutrino in $B$ ($D$) meson decays at Belle II (BESIII)

    hep-ph 2019-08 conditional novelty 6.0 of 10

    A missing-mass search in semileptonic B decays at Belle II could constrain or discover GeV-scale sterile neutrinos, with sensitivity comparable to or better than upgraded LHCb for masses below 2 GeV.

  3. Heavy neutrino mixing prospects at hadron colliders: a machine learning study

    hep-ph 2025-04 conditional novelty 5.0 of 10

    XGBoost applied to simulated same-sign and opposite-sign dilepton events from WR decays in the inverse seesaw left-right model gives projected heavy neutrino mass reaches up to 17.1 and 19.5 TeV at a 100 TeV collider.

  4. Particle physics: a personal view

    hep-ph 2025-04 unverdicted novelty 1.0 of 10

    A senior physicist's essay argues the Standard Model's only genuine flaw is neutrino mass, calls naturalness worries aesthetic, and makes the case that the left-right symmetric theory is the best-motivated BSM candidate.
