${{\mathit p}}$ MAGNETIC RADIUS

INSPIRE   JSON  (beta) PDGID:

S016MCR

This is the rms magnetic radius, $\sqrt {\langle r{}^{2}_{M}\rangle }$.

VALUE (fm) DOCUMENT ID TECN  COMMENT $0.851$ $\pm0.026$ 1 LEE 2015 Combination of world and Mainz data • • We do not use the following data for averages, fits, limits, etc. • • $0.817$ $\pm0.027$ 2 CUI 2021 B FIT use existing ${{\mathit e}}{{\mathit p}}$ data $0.87$ $\pm0.02$ EPSTEIN 2014 Using ${{\mathit e}}{{\mathit p}}$, ${{\mathit e}}{{\mathit n}}$, ${{\mathit \pi}}{{\mathit \pi}}$ data $0.867$ $\pm0.009$ $\pm0.018$ ZHAN 2011 SPEC Recoil polarimetry $0.777$ $\pm0.013$ $\pm0.010$ BERNAUER 2010 SPEC ${{\mathit e}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit e}}{{\mathit p}}$ form factor $0.876$ $\pm0.010$ $\pm0.016$ BORISYUK 2010 Reanalyzes old ${{\mathit e}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit e}}{{\mathit p}}$ data $0.854$ $\pm0.005$ BELUSHKIN 2007 Dispersion analysis 1  In a consistent reanalysis LEE 2015 extract values separately for the Mainz 2010 data only (0.776+-0.034+-0.017) fm and for the world data without Mainz data (0.914+-0.035) fm. The quoted value is a simple combination of the two, which ignores possible discrepancies and unknown correlations and should be considered with caution. 2  CUI 2021B employ a new mathematical procedure (statistical SPM, Schlessinger point method) based on form-unbiased interpolations of existing ${{\mathit e}}{{\mathit p}}$ scattering data.
