-
“In this case, the gaugino mass ratios can be determined only when one can reliably compute the values of the highly UV sensitive \Gamma_\phi and \Omega_ {a\phi}, which is not available with our present understanding of M theory compactification.”
-
You are ready to make your claims that this class of models can accomodate “anything you want” based on the fact that nobody has computed the threshold effects for the anomaly mediated gaugino masses in those models?
-
People can read it for themselves, but I think the Choi-Nilles review is clear in its claims, and they are explicitly not claiming what you are, that string theory leads to specific values for the gaugino mass ratios.
-
No matter what you gaugino mass ratios you see, some model can accomodate it.
-
Broadly speaking, there are a few basic ways of mediating SUSY-breaking to the Standard Model fields, and they tend to be fairly robust in terms of the outcome for basic quantities like the ratios of gaugino masses.
-
One of the inter-relations I was thinking about was the relationship of gaugino masses, which various people have emphasised above.
-
What value of a gaugino mass ratio would falsify string theory. .1?,
-
“People can read it for themselves, but I think the Choi-Nilles review is clear in its claims, and they are explicitly not claiming what you are, that string theory leads to specific values for the gaugino mass ratios.”
-
One such example is the ratios of the gaugino masses.
-
The few “classes” of models people have been able to construct so far where all the moduli are fixed and SUSY is spontaneously broken so that one can honestly compute the F-terms and hence the gaugino masses, scalar masses and the trilinears in terms of the microscopic parameters coming from the Kahler potential and the superpotential are hard to come by.
