Abstract: (APS)
We have searched for negative long-lived penetrating particles of mass between 1.0 and 6.8 GeV/c2 produced by 300-GeV protons incident on Cu. At 2.38-GeV/c transverse momentum no event was found as compared to a yield of 1.28 × 109 π−. The 90%-confidence-level upper limit for the invariant production cross section per nucleon is Edσd3p=5.4×10−39 cm2 GeV−2.References(2)
