The Physics of FINUDA at The DA?NE ?-Factory

• FINUDA studies spectroscopy and decay of hypernuclei

• DA?NE is a source of monochromatic and collinear K+K- pairs, from the decays of the ?(2010) meson

• Negative kaons are stopped in a thin target, and a hypernucleus is formed by replacing a light (up or down) quark with the strange quark carried by the stopped kaon

K-stop + AXZ ? A?XZ + ?-

The momentum of the prompt pion gives the hypernuclear energy level The hypernuclear production is followed by the non-mesonic decays

A?XZ ? AXZ-1 + n + p

or

A?XZ ? AXZ + n + n

The FINUDA event rate: about 100/hour detected hypernuclei at L = 1032 cm-2 s-1

• Other FINUDA physics topics: hypernuclear lifetimes,study of the ?I =1/2 rule, and KN scattering
