A Global χ² Analysis of Electroweak Data (including Fermion Masses and Mixing Angles) in SO(10) SUSY GUTs

الأصل · EN

We present a global χ² analysis of electroweak data, including fermion masses and mixing angles, in SO(10) SUSY GUTs. Just as precision electroweak data is used to test the Standard Model, the well determined Standard Model parameters are the precision electroweak data for testing theories beyond the Standard Model. In this talk we use the latest experimentally measured values for these parameters. We study several models discussed in the literature. One of these models provides an excellent fit to the low energy data with χ² 1 for 3 degrees of freedom. We present our predictions for a few selected points in parameter space.
