Performance of a spherical high pressure gas TPC for neutrino magnetic moment measurement
Résumé
The measurement of neutrino magnetic moment larger than
10$^{-19}$
μB would be a clear signature of physics beyond the
standard model other than the existence of massive Dirac
neutrinos. The use of a spherical proportional counter detector
filled with gas at 40 bar located near a nuclear reactor would be a
simple way to perform such a measurement exploiting the developments
made on such a technology for the search of dark matter and
neutrinoless double beta decay. Different targets can be used just
by replacing the gas: xenon, CF$_{4}$ and argon were compared and the
sensitivity in one year of data taking could reach the level of
4.3 × 10$^{-12}$
μB, 6.5 × 10$^{-12}$
μB, and
8.5 × 10$^{-12}$
μB, respectively.
