2.5 Rates and Sensitivity

Hypernuclear formation rates at the initial luminosity are shown in tab.2, along with rates for background processes.

The rate of reconstructed hypernuclear events with resolution better than 1 MeV at is given by the expression:

where , , is the capture rate, is the total efficiency for forward (high-resolution) prompt pions, and is the chamber transparency.

The FINUDA rate and resolution capabilities are summarized in tab.3, showing beam time required (in hours) at initial luminosity to produce (with 10% and 20% statistical precision) hypernuclear states with capture rates to .
