The analysis is based on the data sample with an integrated luminosity of 32.7 pb$^{-1}$ collected at the VEPP-2000 $e^+e^-$ collider in the center-of-mass energy range $\\sqrt{s}=1.075-2.000$ GeV. The data obtained in the $\\eta\\to 3\\pi^0$ decay mode are found to be in agreement with the previous SND measurements in the $\\eta\\to \\gamma\\gamma$ mode. Therefore the measurements in the two modes are combined.", "revisions": [ { "version": "v1", "updated": "2017-11-24T02:51:54.000Z" } ], "analyses": { "keywords": [ "snd detector", "cross section", "decay mode", "center-of-mass energy range", "snd measurements" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
