A new experiment to search for the invisible decay of the orthopositronium
A. Badertscher, P. Crivelli, W. Fetscher +4
We propose an experiment to search for invisible decays of orthopositronium (o-Ps) with a 90% confidence sensitivity in the branching ratio as low as . Evidence for this d…
An apparatus to search for mirror dark matter via the invisible decay of orthopositronium in vacuum
A. Badertscher, A. Belov, P. Crivelli +9
Mirror matter is a possible dark matter candidate. It is predicted to exist if parity is an unbroken symmetry of the vacuum. The existence of the mirror matter, which in addition t…
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…
A search for charmonium states produced in central pp interactions at 450 GeV/c
The WA102 Collaboration, D. Barberis
A search for centrally produced charmonium states has been presented. There is no significant evidence for any charmonium production. An upper limit of 2 nb is found for the cross…
A study of the f0(1370), f0(1500), f0(2000) and f2(1950) observed in the centrally produced 4pi final states
The WA102 Collaboration, D. Barberis
The production and decay properties of the f0(1370), f0(1500), f0(2000) and f2(1950) have been studied in central pp interactions at 450 GeV/c. The dPT, phi and |t| distributions o…
Experimental evidence for a vector-like behaviour of Pomeron exchange
The WA102 Collaboration, D. Barberis
Evidence is presented that the Pomeron act as a non-conserved vector current. A study has been made of the azimuthal angle phi, which is defined as the angle between the pT vectors…
