Charm and Beauty Decays via Hadronic Production in a Hybrid Emulsion Spectrometer (Fermilab E653)
The goals of E653 are the measurement of lifetimes (especially those of charged and neutral beauty particles and of charmed baryons); study of production dynamics (total cross-section for charm and beauty, Feynman x and transverse momentum distributions, pair correlations, and multiple charm production); search for new states of charm (excited states, exotics); and search for unusual decay modes such as D S to τ (double-kink topology) which require a high-resolution visual technique. Because this visual technique can see nearly all decay vertices, the additional possibility of surprises is always present.
