Latest lattice results for baryon spectroscopy
Authors:D.G.Richards
Abstract:
Theoretical and computational advances have enabled not only the masses of the ground states, but also some of the low-lying excited states to be calculated using Lattice Gauge Theory. In this talk, I look at recent progress aimed at understanding the spectrum of baryon excited states, including both baryons composed of the light u and d quarks, and of the heavier quarks. I then describe recent work aimed at understanding the radiative transitions between baryons, and in particular the N-Roper transition. I conclude with the prospects for future calculations.
