One huge consideration in this decision is that of what will happen at the LHC. CERN is facing its own budgetary problems, and has just decided to shut down during 2012 not just the LHC (for repair of magnet interconnections), but the entire accelerator complex. Work continues this year on trying to raise the luminosity of the machine, but progress is slow. They still are an order of magnitude lower than where they want to be by the end of the year, with only a few more weeks left before the machine is shutdown as a proton-proton collider and reconfigured for a heavy-ion run. If all goes according to plan, by late 2011 the LHC would have 1 fb-1 of data, enough to compete with the Tevatron in the Higgs search. But, so far, plans like this have turned out to be overly optimistic, with things taking longer than expected.
In today’s CERN Bulletin and Fermilab today, Oddone and CERN DG Heuer issued a joint statement downplaying the competition between their labs:
The press makes much of the competition between CERN’s LHC and Fermilab’s Tevatron in the search for the Higgs boson. This competitive aspect is real, and probably adds spice to the scientific exploration, but for us such reporting often feels like spilling the entire pepper shaker over a fine meal.
Using quantum physics, we split your universe into two branches, then we send you an email to inform you which branch you’re in.
As celebrity endorser, they have Garrett Lisi explaining:
The functioning of this app is in complete agreement with the many-worlds interpretation of quantum mechanics.
This semester there’s a program on Langlands Duality in Representation Theory and Gauge Theory at Hebrew University.
There’s a fascinating recent preprint by Kevin Buzzard and Toby Gee on The conjectural connections between automorphic representations and Galois representations. They conjecture a reciprocity sort of relation between algebraic automorphic representations and Galois representations, not just for GL(n), but for arbitrary reductive groups. This involves invoking a twist by “half the sum of the positive roots”, a phenomenon that arises in various places in representation theory, often indictating that spinors are involved (“half the sum of the positive roots” is the highest weight of the spinor representation).
