Status for 2018, CERN NA63

In the NA63 experiment of April 2018 the purpose was to look for the effect of the derivative term, the so-called Schott-term, in classical radiation reaction as described in \cite{DiPiazza20171}. Data was taken for 20, 40 and 80 GeV electrons and positrons aligned to the $\langle100\rangle$ axis of...

Sumario:In the NA63 experiment of April 2018 the purpose was to look for the effect of the derivative term, the so-called Schott-term, in classical radiation reaction as described in \cite{DiPiazza20171}. Data was taken for 20, 40 and 80 GeV electrons and positrons aligned to the $\langle100\rangle$ axis of a diamond crystal of thickness 1.5 mm, as well as for 40 and 80 GeV electrons on a 1.0 mm thick diamond aligned to the $\langle100\rangle$ axis. The data which was taken during the run shows encouraging results, but await a thorough analysis. For the 2017 data, the analysis is still ongoing, but expected to be finished within the coming few months. The results look very promising, but no final conclusion can be drawn at the present stage. For the 2016 results on quantum radiation reaction obtained by CERN NA63, the results have been published in Nature Communications \cite{Wist17}.
