Spectroscopy of $a_1$ mesons from lattice QCD with the truncated overlap fermions

Abstract

We study the ground state and next radial excitation of the $a_1$ mesons from a quenched lattice QCD simulation with the truncated overlap fermions formalism based on domain wall fermions. Our results are consistent with the experimental values for $a_1$(1260) and $a_1$(1640).
