Axial Symmetry Anti-BRST Invariance Modified Anomalies
2010/12/23
It is shown that anti-BRST symmetries are quantized counterparts of local axial symmetries in gauge theories. An extended form of descent equations is worked out which yields a set of modified consist...
Axial and electromagnetic observables of hyperons in 2-flavor chiral perturbation theory
Axial electromagnetic observables of hyperons 2-flavor chiral perturbation theory

Two-flavor chiral expansions provide a useful perturbative framework to study hadron properties.
Such expansions should exhibit marked improvement over the conventional three-flavor chiral
expansion...
Axial and pseudoscalar form-factors of the Delta^+(1232)
Axial pseudoscalar form-factors Delta^+(1232)
2011/1/13
We present first results on the axial and pseudoscalar D form factors. The analysis is carried
out in the quenched approximation where statistical errors are small and the lattice set-up can be inves...
