III. Analysis of V-events

Abstract

Abstract From the observed momenta and angles of decays in flight, variables are constructed which are better suited for the analysis than the measured quantities themselves. These variables are 1/P, the reciprocal of the primary momentum, α, a combination of the longitudinal momenta of the secondaries, and either pt , the transverse momentum, or the quantity ε=2pt/P. The regularities in the distribution of the new variables, to be expected from a two-body decay, are discussed. The decay scheme may be derived by comparison with the experimental distributions.
