Abstract
To reach their physical goals, future neutrino factories using
muon
decay aim at an overall flux precision of
or
better. We analytically study the QED radiative corrections to
the
neutrino differential distributions from muon decay. Kinematic
uncertainties
due to the divergence of the muon beam are considered as well.
The resulting
corrections to the neutrino flux turn out to be
of order
, safely below the required precision.
