abstract

Lepton number violation is searched for at the LHC using same-sign leptons plus jets. The standard lore is that the ratio of same-sign lepton to opposite-sign lepton events, $R_{ll}$, is equal to $R_{ll}=1$ ($R_{ll}=0$) for Majorana (Dirac) neutrinos. We argue that for "quasi-Dirac" neutrinos, $R_{ll}$ can have any value between 0 and 1, the precise value being controlled by the mass splitting versus the width of the quasi-Dirac resonances. A measurement of $R_{ll}\neq 0,1$ would then contain valuable information about the origin of neutrino masses. We consider as an example the inverse seesaw mechanism in a left-right symmetric scenario, which is phenomenologically particularly interesting since all the heavy states in the high energy completion of the model could be within experimental reach. A prediction of this scenario is a correlation between the values of $R_{ll}$ and the ratio between the rates for heavy neutrino decays into standard model gauge bosons, and into three body final states $ljj$ mediated by off-shell $W_R$ exchange.

  1. Dominant Thermal Resonant Mechanism for Low-Scale Leptogenesis

    hep-ph 2026-01 unverdicted novelty 7.0 of 10

    Thermal Resonant Leptogenesis produces the observed baryon asymmetry via a dominant thermal channel from Higgs decays and lepton-doublet coherences, without requiring quasi-degenerate sterile neutrinos.

  2. Probing lepton number violation at FCC-ee

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    Proposes e+e- to N N-bar to ell+ ell+ 4j signatures at FCC-ee in minimal linear seesaw yielding O(10^3) events with negligible SM background to probe LNV and neutrino mass ordering.

  3. Simulations of the Sterile Neutrino Oscillations with a Crossing-Width Term

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A two-step diagonalization plus a dummy-particle trick lets standard event generators simulate GeV-scale sterile neutrino oscillations with crossing-width terms, and a QFT derivation gives displaced-vertex distances.

  4. Low-scale seesaw with flavour and CP symmetries $\unicode{x2013}$ from colliders to leptogenesis

    hep-ph 2024-12 conditional novelty 6.0 of 10

    For four flavour-symmetry cases, this paper maps heavy-neutrino lifetimes, decay flavour ratios, and the parameter space where leptogenesis works and colliders can test it.

  5. Testing the unitarity of the light neutrino mixing matrix

    hep-ph 2026-03 conditional novelty 5.0 of 10

    PMNS non-unitarity would make W+W- production cross sections grow anomalously with energy; LEP data already bound δ_e ≲ 0.0135 and future colliders could reach ~10^-5.

  6. Leptonic CP asymmetry and heavy neutrino searches in seesaw scenario

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    Projects LHC and HL-LHC sensitivities to heavy neutrino mixing via dilepton channels in seesaw scenario, with dependence on R_ll and CP asymmetry.
