Bolton Abstract

As lattice QCD calculations continue to improve, scattering observables are becoming available. The Hadron Spectrum collaboration recently determined the pion-pion spectrum in the rho channel with quark masses that yield a 240 MeV pion. Using Luscher's method, this finite volume spectrum can be used to extract the infinite volume phase shift. The resonant behavior is clearly evident when the phase shift is fit to a Breit-Wigner. This is not the end of the story, though! Having performed the calculation at unphysically-large quark masses, connection with experimental results requires further analysis. We present our use of Unitarized Chiral Perturbation Theory to connect the Hadron Spectrum calculation with experimental results. We find that this chiral extrapolation does an excellent job reproducing experimental pion-pion scattering data.

Degrand Abstract

The years before the Large Hadron Collider turned on saw an active study of alternatives to the Standard Model Higgs boson. Some of this proposed new physics was nonperturbative. A number of researchers adapted the techniques of lattice gauge theory to see if the proposed scenarios were theoretically viable. I recently completed an article for Reviews of Modern Physics on this subject. This talk is an excerpt from the article and gives a big-picture overview of the possibilities for beyond Standard Model physics which have seen lattice activity.
