چکیده
|
We present results of the first ab initio lattice qcd calculation of the normalization constants and first moments of the leading twist distribution amplitudes of the full baryon octet, corresponding to the small transverse distance limit of the associated s-wave light-cone wave functions. the p-wave (higher twist) normalization constants are evaluated as well. the calculation is done using n f = 2 + 1 flavors of dynamical (clover) fermions on lattices of different volumes and pion masses down to 222 mev. significant su(3) flavor symmetry violation effects in the shape of the distribution amplitudes are observed.
