New empirical fits to the proton electromagnetic form factors

Recent measurements of the ratio of the elastic electromagnetic form factors of the proton, ${G}_{\mathrm{Ep}}{/G}_{\mathrm{Mp}},$ using the polarization transfer technique at Jefferson Lab, show that this ratio decreases dramatically with increasing ${Q}^{2},$ in contradiction to previous measurements using the Rosenbluth separation technique. Using these new high quality data as a constraint, we have reanalyzed most of the world $\mathrm{ep}$ elastic cross section data. In this paper, we present a new empirical fit to the reanalyzed data for the proton elastic magnetic form factor in the region $0l{Q}^{2}l30 {\mathrm{GeV}}^{2}.$ As well, we present an empirical fit to the proton electromagnetic form factor ratio, ${G}_{\mathrm{Ep}}{/G}_{\mathrm{Mp}},$ which is valid in the region $0.1l{Q}^{2}l6 {\mathrm{GeV}}^{2}.$
