The fact that neutrinos are massive indicates that the Standard Model (SM) requires extension. We propose a low energy (<TeV) B-L extension of the SM, which is based on the gauge group SU(3)_C x SU(2)_L x U(1)_Y x U(1)_{B-L}. We show that this model provides a natural explanation for the presence of three right-handed neutrinos in addition to an extra gauge boson and a new scalar Higgs. Therefore, it can lead to very interesting phenomenological implications different from the SM results which can be tested at the LHC. Also we analyze the muon anomalous magnetic moment in this class of models. We show that one-loop with exchange Z' may give dominant new contribution ~ few x 10^{-11}.

  1. Custodial Naturalness

    hep-ph 2025-02 conditional novelty 6.0 of 10

    Custodial Naturalness uses classical scale invariance plus a custodial SO(6) symmetry to make the Higgs a naturally light pseudo-Goldstone boson, with testable new particle predictions.

  2. Exploring $Z'$ and Right-Handed Neutrinos in the BLSM at the Large Hadron Collider

    hep-ph 2024-12 conditional novelty 5.0 of 10

    For a benchmark B-L extension with a 3 TeV Z' and 420 GeV right-handed neutrinos, the HL-LHC could reach discovery-level significance in three final states using BDT-based event selection.

  3. Characterisation at the HL-LHC of Long-lived Heavy Neutrinos in Gauge Extensions of the Standard Model

    hep-ph 2026-07 conditional novelty 4.0 of 10

    Displaced heavy-neutrino signals in LRSM and U(1)B−L remain accessible at the HL-LHC, with parton-level mass, lifetime, and AFB handles in low-background regions.

  4. The $Z'$-boson of the $B-L$ Supersymmetric Standard Model and its Large Hadron Collider Searches

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    In the BLSSM, Z' masses down to 2.24 TeV remain allowed when the boson is fat, leptophobic, or has large branching ratios to model-specific states while respecting LEP/SLC and LHC constraints.
