We investigate the possibility that quarks and leptons are unified at a low energy scale much smaller than the grand unified scale. A simple theory for quark-lepton unification based on the gauge group SU(4)_C X SU(2)_L X U(1)_R is proposed. This theory predicts the existence of scalar leptoquarks which could be produced at the Large Hadron Collider. In order to have light neutrinos without fine tuning, their masses are generated through the inverse see-saw mechanism.

  1. Matter Unification and Lepton Flavour Violation

    hep-ph 2026-03 conditional novelty 6.0 of 10

    Muon-to-electron conversion at Mu2e can probe quark–lepton unification scales up to ~10^4 TeV in the minimal SU(4)_C×SU(2)_L×U(1)_R model, even where rare kaon decays are suppressed by unknown mixing angles.

  2. Universal Seesaw Pati-Salam Model with P for Strong CP

    hep-ph 2025-12 conditional novelty 6.0 of 10

    A parity-symmetric Pati-Salam model with universal seesaw masses gives an axionless strong-CP solution and radiatively induced neutrino masses.

  3. Quark-Lepton Unification Signatures

    hep-ph 2025-11 conditional novelty 5.0 of 10

    In the minimal low-scale quark-lepton unification model, scalar leptoquarks decay mainly to third-generation quarks and leptons, and current LHC measurements exclude masses below roughly 1.0–1.15 TeV in the y2=0 benchmark.

  4. Hunting and identifying coloured resonances in four top events with machine learning

    hep-ph 2025-06 conditional novelty 5.0 of 10

    A neural network analysis of four-top events projects discovery of colour octet and sextet scalars up to about 1.8 to 1.9 TeV at the HL-LHC and can distinguish their colour representations.
