A Global chi^2 Analysis of Electroweak Data in SO(10) SUSY GUTs
We present the details of a global 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 paper 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 for 3 degrees of freedom. We present
graphs of constant contours as functions of position in soft SUSY
breaking parameter space, as well as our predictions for a few selected points
in parameter space. We also study the sensitivity of our results to changes in
various parameters. Finally, we discuss the consequences of our work in the
context of a general MSSM analysis at the Z scale.Comment: 37 pages, Latex, 14 figures included in separate file
