Weinberg Angle and Integer Electric Charges of Quarks
Martin A. Faessler ;
Date 22 Aug 2013
AbstractOrthogonality between photon and Z boson involves the Weinberg angle and a scheme for assignments of electric charge and weak isospin to leptons and quarks coupling to photon and Z. The Han-Nambu scheme, with integer electric charges for quarks, satisfies photon-Z orthogonality with sin^2(theta_W)= 0.25 in leading order. Experimental results for photon-photon fusion into charm-anticharm and bottom-antibottom pairs provide further support for assigning integer electric charges to quarks.
