![]() The X ± and Y ± bosons are defined respectively as the six Q = ± 4 / 3 and the six Q = ± 1 / 3 components of the final two terms of the adjoint 24 representation of SU(5) as it transforms under the standard model's group:Ģ4 → ( 8, 1 ) 0 ⊕ ( 1, 3 ) 0 ⊕ ( 1, 1 ) 0 ⊕ ( 3, 2 ) − 5 6 ⊕ ( 3 ¯, 2 ) 5 6 X bosons rotate between a color index and the weak isospin-up index, while Y bosons rotate between a color index and the weak isospin-down index. − pair is created out of energy, and they follow the two branches described above: Different branching ratios between the X boson and its antiparticle (as is the case with the K-meson) would explain baryogenesis. In these reactions, neither the lepton number ( L) nor the baryon number ( B) is separately conserved, but the combination B − L is. Similar decay products exist for the other quark-lepton generations. The first product of each decay has left-handed chirality and the second has right-handed chirality, which always produces one fermion with the same handedness that would be produced by the decay of a W boson, and one fermion with contrary handedness ("wrong handed").

Significantly, the X and Y bosons couple quarks (constituents of protons and others) to leptons (such as positrons), allowing violation of the conservation of baryon number thus permitting proton decay. Since the X and Y boson mediate the grand unified force, they would have unusual high mass, which requires more energy to create than the reach of any current particle collider experiment. In particle physics, the X and Y bosons (sometimes collectively called " X bosons" : 437 ) are hypothetical elementary particles analogous to the W and Z bosons, but corresponding to a unified force predicted by the Georgi–Glashow model, a grand unified theory (GUT).
