Additional topics covered by LHEP include astrophysics, gravity, and cosmology. LHEP publishes articles in the letter format.</p> <p>The goal is to provide the high energy physics community with a medium through which researchers are able to publish informative summaries of important findings in the field.</p> <p style="text-align: justify;"><span style="font-family: 'Minion W08 Regular_1167271',Times; font-size: 17px; font-variant-ligatures: normal; background-color: #ffffff;"> </span></p>http://journals.andromedapublisher.com/index.php/LHEP/article/view/136Polarizability of the nucleon2019-11-14T18:16:02+00:00Martin Schumachermschuma3@gwdg.de<p>The status of the experimental and theoretical investigations of the nucleon is presented. This includes a confirmation of the validity of the previously introduced recommended polarizabilities. It is shown that the only meaningful approach to a prediction of the polarizabilities is obtained from nonsubtracted dispersion theory, where the appropriate degrees of freedon taken from other precise experimental data are taken into account. The present values of the recommended polarizabilities are \(\alpha_p=12.0\pm 0.5\), \(\beta_p=1.9\mp 0.5\), \(\alpha_n=12.6\pm 1.2\), \(\beta_n=2.6\mp 1.2\) in units of \(10^{-4}\)fm\(^3\) and \(\gamma^{(p)}_\pi =-36.4 \pm 1.5\), \(\gamma^{(n)}_\pi=+58.6\pm 4.0\), \(\gamma^{(p)}_0= -0.58\pm 0.20\), \(\gamma^{(n)}_0=+0.38\pm 0.22\) in units of \(10^{-4}\)fm\(^4\).</p>2019-11-11T22:26:21+00:00##submission.copyrightStatement##
