delta. I = 1/2 rule and Glashow-Iliopoulos-Maiani current with unconfined color

Journal Article · · Phys. Rev., D; (United States)
;
We study a four-flavor model with unconfined color in the framework of the SU(2)/sub L/ x U(1) gauge model. The presence of a color-octet charged current leads to a violation of the universality of the hadronic and leptonic currents; therefore, heavy leptons are needed inevitably to compensate the violation. A condition for cancellation of (84,1) representation in the combination of current products (15,1) x (15,1) + (15,8) x (15,8), which explains successfully the observed ..delta..I = 1/2 rule, leads to the result that the slope of the linearly rising cross section sigma (..nu../sub ..mu../(nu-bar/sub ..mu../) N ..-->.. ..mu../sup -/(..mu../sup +/) X) must be more than twice as large at energies high enough to produce the color-octet states as it is at lower energies, even if the effects of the weak boson and heavy leptons are taken into account.
