Therefore the green band really represents the general prediction of the MSSM (well, ok, we left out points with a very large mass splittings between stops and sbottoms, which result in W masses that are even larger (and experimentally excluded)).

From the remarks above the graph, a naive reader might guess it stands for the Higgs mass (since the horizontal axis is the top quark mass). By cheating and peeking at the "better version in eps", I discovered it's the W mass. hktelemacher wrote:

Vlad, please see my update in the post above. hktelemaker, this blog offers you the chance to do so. Please visit the "physics made easy" section. You will find some plots describing in easier terms and more detail the plot you are looking at above. Hi Lubos, thank you for your post too. Hello Quasar9, welcome back! Please visit often and let me know if there's anything in particular I could offer to review here, among new Tevatron results. I also have little time this summer (you can sort of notice it from my reduced throughput here) but I'll see what I can do... Vlad, Sven's plot is best described in his web page. But I would also advise you to read his latest preprints, which discuss how one can fit together electroweak observables and cosmological constraints, together with b-physics observables, in the context of some constrained SUSY scenarios. Check, for instance: http://xxx.lanl.gov/abs/0805.2359 Cheers, T. Hi Higgsy,
