leptoquark

[′lep·tō‚kwärk]
(particle physics)
A hypothetical elementary particle; a colored technipion with a mass of the order of 100-300 GeV, which would decay into a lepton plus a quark.

In leptoquark models the [a.sub.LR]-interaction arises from mixing of leptoquarks of different SM quantum numbers.
One possibility is that a positron may merge briefly with a quark, creating a particle that theorists call a leptoquark. This particle would then decay and spit out a positron.

Interestingly the masses of [W.sub.R] boson and leptoquark gauge bosons of SU[(4).sub.C] have been predicted at ~100 TeV which could be accessible to planned LHC at those energies where [W.sub.R] boson scale ~(100-1000) TeV matching with observable n - [bar.n] oscillation and rare kaon decay have been predicted.
One of the important new physics models that has been proposed to overcome the problems of some inconsistencies between the SM predictions and experimental data is the leptoquark (LQ) model.
We also note that the values obtained for the intermediate scale (where the Pati-Salam is broken) and the unification scale are sufficiently high to remain compatible with the experimental constraints regarding the leptoquark induced effects and the proton decay.
The model also predicts the existence of particles called leptoquarks, which, in principle, could be detected in a proton-electron collider nearing completion in Germany.
