On the colour contribution to effective weak vertex in broken colour gauge theories

  • R Ramachandran
Nuclear And Particle Physics


Treating the breaking of colour symmetry via the mixing between the colour gluons and weak bosons (a la Rajasekaran and Roy) it is observed that the colour contribution to the effective weak vertex of a quark at zero momentum transfer is zero uptoO(α).
