Dear Dr. Kane,
Oops! Upon skimming your arXiv paper, I realize you are talking about a neutral wino LSP (in your Pamela abstract). I probably would have called it a zino or bino to minimize confusion with the charged wino. I see that a 180 GeV neutral wino fits much of the data, but we should expect this bino-neutralino to also have higgsino and trace amounts of photino characteristics. Can we fit the data better by mixing in some higgsino?
I don't think we ever met, but I studied under Howie Baer with your former post-doc, Mike Brhlik. Mike was a year behind me, but we were officemates.
You mention a string theory model compactified on a manifold with G2 holonomy. Lawrence Crowell (also in this contest) and I are also trying to build models that might connect with a multi-dimensional supersymmetric string theory on the high-energy side and the Standard Model on the low-energy side. Lawrence also has a G2 holonomy. I have a G2 buried in the Color theory component of my model, but can't decide if the SUSY part of my model is G2 or I2(7) (details in my Ref.3 - A Case Study 3.3.pdf posted on my essay blog site).
Be careful! There are rogues in this voting process. The majority of my votes have been 8's or 1's - they either love or hate me! It seems that you are getting the same response.
Good Luck!
