| Summary: | Tau neutrino is one of the least known particle of Standard Model;
there are only few measurements with a limited statistics. The DONUT
experiment first reported the tau neutrino interaction cross-section but
their measurement suffers from large systematic error of more than
50\%
50
%
which is mainly due to uncertainty in the tau neutrino flux prediction.
The tau neutrino cross section is an essential ingredient in neutrino
experiments and its precise measurement would enable a search for new
physics effects such as testing the Lepton Universality in neutrino
interactions. The main goal of the DsTau experiment is to measure an
inclusive differential cross-section of a
D_s
D
s
production with a consecutive decay to tau lepton in p-A interactions at
the CERN-SPS. The measurement of DsTau will reduce the systematic
uncertainty in tau neutrino interaction cross-section to
10\%
10
%
level. The results from the pilot run and the prospect for physics runs
in 2021-2022 will be discussed. |
