Excited states in the full QCD hadron spectrum on a $16^3 \times 40$ lattice

Abstract

We report the hadron mass spectrum obtained on a $16^3 \times 40$ lattice at $\beta = 5.7$ using two flavors of staggered fermions with $m a = 0.01$. We calculate the masses of excited states that have the same quantum numbers as the $\pi$, $\rho$ and $N$. They are obtained by a combined analysis of the hadron correlators from sources of size $16^3$ and $8^3$. We also report on the hadron spectrum for a wide range of valence quark masses.Comment: Contribution to Lattice 95. 4 pages. Compressed, uuencoded postscript file. Send questions to [email protected]
