MixMatch
Estimate an approximating Gaussian mixture for observed data that maximizes the expected log pointwise predictive density.
Extracting the pion-nucleon sigma term from the lattice [seminar]
Lawrence Berkeley National Lab [seminar] [PDF of slides]
In this talk, I will give an overview of the nucleon sigma term and its applications, particularly its central role in direct dark matter searches. I will briefly summarize and contrast some recent work and describe how CalLat intends to calculate this quantity. Finally I will present some preliminary work from our collaboration.
