Kuarkls

Kuarkls are a hypothetical class of elementary particles proposed in speculative physics as an extension of the quark model. In typical sketches, kuarkls are fermions that participate in a new, strong-like interaction and come in multiple types, or flavors, and colors that mediate their binding into composite states called kuarkl-hadrons.

In these models, kuarkls may carry fractional electric charges or neutral charges, depending on the variant, and are bound by a gauge symmetry distinct from quantum chromodynamics, often denoted SU(3)_K. The theory often introduces a corresponding force carrier, the gluon-like kuarkl-boson, and predicts rich spectroscopy of kuarkl-mesons and kuarkl-baryons.

Status: Kuarkls have no experimental evidence. They appear in theoretical proposals to address questions such as dark matter composition, the matter–antimatter asymmetry, or as a conceptual extension to the standard model. Proposals differ on whether kuarkls mix with ordinary quarks, how they interact with leptons, and their mass scales, which are typically assumed well above standard-model particle masses.

Impact and research: If real, kuarkls would imply new bound states, novel collider signals, and potential implications for cosmology. Experimental searches usually focus on high-energy collider data, rare decays, and astrophysical observations for signatures of stable or long-lived kuarkls.
