${{\boldsymbol p}}$ ELECTRIC POLARIZABILITY ${{\boldsymbol \alpha}_{{p}}}$ INSPIRE search

For a very complete review of the ``polarizability of the nucleon and Compton scattering,'' see SCHUMACHER 2005 . His recommended values for the proton are ${{\mathit \alpha}_{{p}}}$ = ($12.0$ $\pm0.6$) $ \times 10^{-4}~$fm${}^{3}$ and ${{\mathit \beta}_{{p}}}$ = (1.9 $\mp{}$ 0.6)${\times }10^{-4}$ fm${}^{3}$, almost exactly our averages.

1  BEANE 2003 uses effective field theory and low-energy ${{\mathit \gamma}}{{\mathit p}}$ and ${{\mathit \gamma}}{{\mathit d}}$ Compton-scattering data. It also gets for the isoscalar polarizabilities (see the erratum) $\alpha _{\mathit N}$= ($13.0$ $\pm1.9$ ${}^{+3.9}_{-1.5}$) $ \times 10^{-4}$ fm${}^{3}$ and $\beta _{\mathit N}$= ($-1.8$ $\pm1.9$ ${}^{+2.1}_{-0.9}$) $ \times 10^{-4}$ fm${}^{3}$.
2  BLANPIED 2001 gives ${{\mathit \alpha}_{{p}}}+{{\mathit \beta}_{{p}}}$ and ${{\mathit \alpha}_{{p}}}−{{\mathit \beta}_{{p}}}$. The separate ${{\mathit \alpha}_{{p}}}$ and ${{\mathit \beta}_{{p}}}$ are provided to us by A.$~$Sandorfi. The first error above is statistics plus systematics; the second is from the model.
3  This OLMOSDELEON 2001 result uses the TAPS data alone, and does not use the (re-evaluated) sum-rule constraint that ${{\mathit \alpha}}+{{\mathit \beta}}$= ($13.8$ $\pm0.4$) $ \times 10^{-4}~$fm${}^{3}$. See the paper for a discussion.
4  MACGIBBON 1995 combine the results of ZIEGER 1992 , FEDERSPIEL 1991 , and their own experiment to get a ``global average'' in which model errors and systematic errors are treated in a consistent way. See MACGIBBON 1995 for a discussion.
5  BARANOV 2001 combines the results of 10 experiments from 1958 through 1995 to get a global average that takes into account both systematic and model errors and does not use the theoretical constraint on the sum $\alpha _{{{\mathit p}}}+\beta _{{{\mathit p}}}$.
6  FEDERSPIEL 1991 obtains for the (static) electric polarizability ${{\mathit \alpha}_{{p}}}$, defined in terms of the induced electric dipole moment by $\mathbf {D}$ = 4$\pi \epsilon _{0}{{\mathit \alpha}_{{p}}}\mathbf {E}$, the value ($7.0$ $\pm2.2$ $\pm1.3){\times }10^{-4}~$fm${}^{3}$.
