Vector Meson Spectroscopy in PP̄ → e⁺e^- X

Abstract

The main goal of the experiment PS 170 is the measurement of the proton form factor from the reaction:

$$ p\bar p \to {e^ + }{e^ - } $$

((1))

but the experimental set-up can also detect inelastic reactions such that:

$$ p\bar p \to {e^ + }{e^ - }X $$

((2))

where X is a neutral system, more likely a π°.
