Abstract :
In spring 2003 the FINUDA detector was installed at the ϕ factory DAΦNE in the Laboratori Nazionali di Frascati of INFN (Italy). In October 2003 the commissioning of the apparatus was accomplished and the first data taking started with a set of nuclear targets 6Li, 7Li, natC, 27Al, 51V. The data collection will continue until a total integrated luminosity of 250 pb−1 is recorded. Light and medium A hypernuclei will be abundantly produced by the strangeness exchange reaction induced by the stopped K− coming from the decay of ϕ(1020) mesons.
The aim of the experiment is to simultaneously measure the excitation energy spectra of the produced hypernuclei, with a resolution better than 1 MeV, the lifetime of the Λ embedded in the different hypernuclei and the partial widths Γπ, Γnp and Γnn for mesonic and non-mesonic hypernuclear decays. Information on neutron-rich hypernuclei and rare hypernuclear two-body decays might be available too, with the statistics that will be collected at the end of the run.
In the present paper, first results concerning in-beam detector calibration, spectrometer performances and very preliminary hypernuclear formation and decay spectra will be presented.
