A few short items:
- No Higgs news on the LHC front, but on the BSM front today’s CERN talk Update on Searches for New Physics in CMS provides more evidence against the various exotic scenarios heavily advertised over the last twenty years. No sign of extra dimensions, SUSY, or other exotics. For more, see Resonaances. SUSY proponents now seem to be somewhere between the first stage of grief (“denial”) and the second (“anger”, see e.g. here) and on their way to the third (Bargaining – “I’ll do anything for a few more years”).
- From Sean Carroll’s Twitter feed I learned about this long description of a recent workshop bringing together philosophers and quantum field theorists. I guess my take on the “heuristic” vs. “mathematical” quantum field theory debate is that we need both, since there is still a huge amount we fundamentally don’t understand about QFT.
- For a finite number of degrees of freedom, quantum mechanics itself is, unlike QFT, rather well understood. For a nice recent review of some topics in the mathematics of quantization, see Ivan Todorov’s Quantization is a mystery.
- It’s not only string theorists producing over-hyped university press releases, there’s things like this. See more discussion here.
