Masses and mixing angles in SU(5) gauge model

Creators

Description

Georgi and Jarlskog mass relations m/sub μ/m/sub e/ = 9m/sub s//m/sub d/, m/sub b/ = m/sub tau/ are obtained above the grand unification mass M = 1015 GeV with two approx. 5's and one approx. 45 Higgs representations of SU(5) and a discrete symmetry. In the lowest order, the Kobayashi-Maskawa angles are found to be s2 = -(m/sub c//m/sub t/) /sup 1/2/ and s3 = -(m/sub u//m/sub t/) /sup 1/2//s1, where s1 is the sine of the Cabibbo angle. The CP violation is considered, and the b quark decays predominantly into c quarks with lifetime of tau/sub b/ approx. equal to 10-13 s for m/sub t/ = 25 GeV
