New limits on the nuclear levels excitation of 127I and 23Na during charge nonconservation
No full textSome electroweak models with extended neutral currents, such as those based on the E6 group, lead to an increase of the ν¯−e scattering cross section at energies below 100 keV. We propose to search for the heavy Z' boson contribution in an experiment with a high-activity artificial neutrino source and with a large-mass detector. We present the case for the LAMA experiment with a large NaI(Tl) detector located at the Gran Sasso underground laboratory. The neutrino flux is known to within a one percent accuracy, in contrast to the reactor case and one can reach lower neutrino energies. Both features make our proposed experiment more sensitive to extended gauge models, such as the χ model. For a low enough background the sensitivity to the Zχ boson mass would reach 600 GeV for one year running of the experiment
Search for neutrino magnetic moment deeply underground
No full textWe present here a project to search for a neutrino magnetic moment in the range 10§^-10 - 10^-11 mu_b by using a 147Pm antineutrino source and a large mass high radiopurity NaI(Tl) set-up deep undergroun
