Muon-decay parameters from COHERENT
Víctor Bresó-Pla, Sergio Cruz-Alzaga, Martín González-Alonso, Suraj Prakash
We demonstrate that measurements of Coherent Elastic Neutrino-Nucleus Scattering (CEνNS) at spallation sources are valuable probes of muon-decay physics. Using COHERENT data we derive the first direct constraint on the Michel parameters governing the ν¯μ energy distribution. We also discuss future sensitivities and assess the implications for the Lorentz structure of the interactions mediating muon decay.
We have been invited to give a parallel talk at Neutrino Telescopes in Padova, at the end of September/beginning of October.

If anyone is interested in attending, we would have to submit an abstract (deadline is June 16). Parallel talks should be 15’ + questions. Alternatively there is the possibility to present a poster.
