Neil Weiner gave a great brown-bag (all chalk) talk about the Higgs at lunch today. He started from scratch: He started at the Lagrangian in field theory and ended up saying what the implications are for new physics (especially supersymmetry-like theories) of various different Higgs masses! And all in 50 minutes. It was a masterpiece, and hilarious to boot. Ask him for his joke about string theorists.
Before and after that, Hou showed us the results of fitting a stochastic stellar oscillation model to K-giant radial velocity data. We are hoping to show that including a physical model for surface variations will improve the results of exoplanet fitting. We can show this for fake data; now onto real data.
Good to hear that the oscillation model is working out. Are you using the state space representations method (likelihood calcs take O(N)) or the naive "Gaussian process" method (O(N^3)) like I did?
ReplyDelete@Brendon: Interesting! Let's discuss when you are here.
