Charm and Beauty Decays via Hadronic Production in a Hybrid Emulsion Spectrometer (Fermilab E653)

  • Noel R. Stanton
Part of the NATO ASI Series book series (NSSB, volume 197)


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.
