Hi, I'm Jeff Jones... a PhD candidate in high energy theoretical physics at UCSC. My area of interest is gauge mediated supersymmetry breaking, and its phenomenological implications for collider physics and cosmology. Most of my work has focused on Tom Banks' Pentagon model, an example of direct gauge mediated SUSY breaking with a strongly coupled hidden sector. Currently, I'm investigating the sparticle spectrum in the Pentagon, and its successor the Pyramid. My last paper was a 2-loop analysis of gauge coupling unification for theories which extend the visible sector with 5 flavors. Prior to that, with Banks and Sean Echols, I embedded the Pentagon model into an SU(5)xSU(5)xSU(5) Grand Unified Theory. Before that, we proposed a new mechanism for baryogenesis, which involves a hypothetical connnection between dark matter and the baryon asymmetry.
In August 2008, I started writing a more widely accessible explanation (aimed at intelligent non-physicists) of what I do, trying to give as much background as possible. It starts from a general explanation of what the point of "high energy physics" is, and fills in the gaps from there. Unfortunately, I realized as I was writing it that it would have to be much longer than I'd originally realized to do a decent job. So I started it in August, and added a bit to it in September, but haven't really touched it since. I intend to finish it at some point, perhaps separating it into multiple hyperlinked web pages. Here is the current draft, with lots of sections yet to be filled in, and some modifications and clarifications of current sections needed (for example, the latest delays in the LHC startup schedule).

- Dec 11, 2008: I have submitted my paper on gauge coupling unification. You can download the preprint from arXiv.org here: [arXiv:0812.2106] Gauge Coupling Unification in the MSSM + 5 Flavors.
*UPDATE* - April 16, 2009: My gauge coupling unification paper has now appeared in Physical Review D: Gauge Coupling Unification in the MSSM + 5 Flavors
