Thursday morning session has started with the latest results about coherent elastic neutrino-nucleus scattering searches.

The COHERENT collaboration has presented the reported observation of this process with a significance of 6.7σ. All the details about this result, published in August last year, can be found in their paper. The theoretical implications for new physics have been discussed by Omar Miranda.

The CONUS collaboration also aims to measure the coherent elastic neutrino-nucleus scattering from reactor neutrinos. They have reported on the status of their experiment, which started taking data last 1st of April. The future of this kind of experiments has been reviewed by Henry Wong.

The second session has been dedicated to laboratory neutrino mass determination.

The KATRIN collaboration has shown first preliminary results of the tritium beta decay end-point spectrum. This data was taken just 3 weeks ago and allowed to test the stability and response of the experiment. Full tritium runs are expected to start in early 2019 with the expected sensitivity to the effective neutrino masses up to 0.24 eV after five years.

The HOLMES and ECHO experiments will perform complementary measurements of the neutrino mass from ¹⁶³Ho beta decays. Very preliminary results from ECHO have also been presented.
