Latest results from FENICE

The FENICE apparatus to measure the electromagnetic form factor of the neutron was built at the ADONE storage ring in Frascati and the reaction e+ e- > n nbar has been studied in the energy region between the threshold and 2.44 GeV in the center of mass. Preliminary results at 2.0 and 2.1 GeV have already been reported. New results are now available that confirm the eletromagnetic form factor of the neutron |Gn| not lower that proton form factor |Gp|

Measurement of the electromagnetic form factor of the proton in the time-like region

The cross section for the process e+e- >> p pbar has been measured in the s range 3.6–5.9 GeV2 by the FENICE experiment at the e+e− Adone storage ring and the proton electromagnetic form factor has been extracted

Some final results from the FENICE experiment

The first measurement of the neutron form factor in the time-like region has been produced in tha Fenice experiment by studying the e+ e- > n nbar reaction at the Adone storage ring.The most recent results at the energies of 1.92, 2.0, 2.1 GeV in the center of mass are reported in this paper

The Fenice Detector At the E+e- Collider Adone

The FENICE detector, installed at the Frascati e+e- storage ring ADONE, for measuring the neutron e.m. form factors in the timelike region, is described. FENICE is a nonmagnetic detector and consists of a complex array of scintillators, limited streamer tubes and iron converters for detecting mainly the process e+e- --> nnBAR. Antineutrons are identified by the charged prongs produced in their annihilation and the antineutron velocity is measured by the retrieved annihilation time with respect to the beam crossing time. Neutrons are detected in plastic scintillator layers. To reduce the cosmic rays background a concrete shield, covered by an active veto system, is added

Bottomonium and Drell-Yan production in p-A collisions at the CERN SPS

In the past few years the NA50 experiment carried out a comprehensive study of heavy quarkonia production, both in proton-nucleus and nucleus-nucleus collisions. In particular, data from p-A collisions have been collected in order to estimate the size of the absorption of quarkonia states in cold nuclear matter. Along with the studies on J/psi and psi', NA50 measured for the first time Y production at 450 GeV incident energy ( sqrt(s)=29.1 GeV) on five nuclear targets (Be, Al, Cu, Ag and W) in the dimuon decay channel. We report here results on the cross section at mid-rapidity and the nuclear dependence of Y and Drell-Yan production. We analyzed as well the transverse momentum and rapidity distributions for the Y meson. The results are compared with previous measurements and with the predictions of theoretical models
