High-Energy Physics & RIKEN Theory Seminar

"Electromagnetic Splitting of Charged and Neutral Mesons"

Presented by Aaron M. Torok, Indiana University

Wednesday, March 30, 2011, 2:00 pm — Small Seminar Room, Bldg. 510

We calculated the electromagnetic splittings of charged and neutral mesons, and the violation of Dashen's theorem. The meson masses are calculated with Lattice QCD using the MILC ensembles. U(1) gauge fields are generated independently. The computationally intensive part of the SU(3)xU(1) calculation is done using an implementation of the MILC staggered multi-mass inverter that originally ran on one GPU, and now runs on many. An extrapolation to the physical point is underway using staggered chiral perturbation theory.
