Search for exotic states, BNL experiments E818 and E852.

摘要

We have performed an experiment (E-818) to search for exotic states in the reaction (pi)(sup (minus))p (yields) X(sup (minus))p at 18 GeV/c at the Brookhaven MPS-2. The X(sup (minus)) was detected through the sequential decay X(sup (minus)) (yields) f(sub ...
