Light-Cone Distribution Amplitudes of N$^*$(1535) from Lattice QCD
ORAL
Abstract
We present the results of a lattice calculation of the first two moments of the light-cone distribution amplitudes of the lowest positive parity resonance, N$^*$(1535). The calculation is done on lattices with Nf = 2 flavors of dynamical Clover fermions. We have used lattices with several volumes, lattice spacings and pion masses, the lightest one being close to the physical pion mass. To select the N* state, we have used improved parity projection and the variational approach.
