Status for 2017, CERN NA63

Abstract

In the NA63 experiment of May-June 2017 the purpose was to look for the effect of classical radiation reaction as described in \cite{DiPiazza20171} but for 50 GeV positrons aligned to the (110) plane of silicon crystals of varying thicknesses in the range 1-6 mm. The data which was taken during the run shows promising results, but the final verdict awaits accurate calculations of the theoretically expected spectra, and a final analysis. For the 2016 results on quantum radiation reaction obtained by CERN NA63, we have submitted a manuscript, which is presently under refereeing \cite{Wist17}
