A low energy optimization of the CERN-NGS neutrino beam for a theta_{13} driven neutrino oscillation search
A. Rubbia, P. Sala
The possibility to improve the CERN to Gran Sasso neutrino beam performances for theta_{13} searches is investigated. We show that by an appropriate optimization of the target and…
Proton driver optimization for new generation neutrino superbeams to search for sub-leading numu->nue oscillations ( angle)
A. Ferrari, A. Rubbia, C. Rubbia +1
We perform a systematic study of particle production and neutrino yields for different incident proton energies and baselines , with the aim of optimizing the parameters o…
Search for an exotic three-body decay of orthopositronium
A. Badertscher, P. Crivelli, M. Felcini +7
We report on a direct search for a three-body decay of the orthopositronium into a photon and two penetrating particles, o-Ps -> gamma + X1 + X2. The existence of this decay could…
Invisible decay of orthopositronium vs extra dimensions
S. N. Gninenko, N. V. Krasnikov, A. Rubbia
In models of Randall-Sundrum type orthopositronium (o-Ps) can disappear due to tunnelling into additional dimension(s). The experimental signature of this effect is the invisible d…
