Model independent sum rules for strange form factors

We study chiral models with SU(3) group structure such as Skyrmion and chiral bag to yield theoretical predictions of proton strange form factor comparable to the recent experimental data of the SAMPLE Collaboration. For these predictions we formulate model independent sum rules for proton strange form factor in terms of baryon octet magnetic moments. We also investigate the Becci-Rouet-Stora-Tyutin symmetries associated with the St\"uckelberg coordinates, ghosts and anti-ghosts involved in the Skyrmion model.
