Letters in High Energy Physics http://journals.andromedapublisher.com/index.php/LHEP <p>Letters in High Energy Physics (LHEP) is a quarterly, peer-reviewed, hybird open access journal which specializes in theory, phenomenological, and experimental aspects of particle physics. Additional topics covered by LHEP include astrophysics, gravity, and cosmology.&nbsp; 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;">&nbsp;</span></p> en-US <p align="justify">Letters in High Energy Physics (LHEP) is an open access journal published by Andromeda Publishing and Education Services.

This includes a confirmation of the validity of the previously&nbsp; introduced recommended&nbsp; polarizabilities. It is shown that the only meaningful approach to a prediction of the polarizabilities&nbsp; is obtained from nonsubtracted dispersion theory, where the appropriate degrees of freedon taken from other precise experimental data are taken into account. The present&nbsp; values of the recommended polarizabilities are \(\alpha_p=12.0\pm 0.5\), \(\beta_p=1.9\mp 0.5\), \(\alpha_n=12.6\pm 1.2\),&nbsp; \(\beta_n=2.6\mp 1.2\) in units of \(10^{-4}\)fm\(^3\) and \(\gamma^{(p)}_\pi =-36.4 \pm 1.5\),&nbsp; \(\gamma^{(n)}_\pi=+58.6\pm 4.0\), \(\gamma^{(p)}_0= -0.58\pm 0.20\), \(\gamma^{(n)}_0=+0.38\pm 0.22\) in units of \(10^{-4}\)fm\(^4\).</p> Martin Schumacher ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 http://journals.andromedapublisher.com/index.php/LHEP/article/view/136 Mon, 11 Nov 2019 22:26:21 +0000
