Meson masses at large N

Presenter: Francis Bursa — Universitšt Regensburg

Gunnar Bali and Francis Bursa

We analyze the meson spectrum in SU(N) lattice gauge theory. We use Wilson quarks to measure the pseudoscalar and vector masses in SU(2), SU(3), SU(4) and SU(6), and extrapolate to the large-N limit. We find that finite-N corrections are small at all values of the quark mass.
