ABSTRACT: We have studied interactions of 200, 300, and 400 GeV protons with beryllium and tungsten targets, in which two large-pt hadrons were produced roughly back-to-back near 90° in the proton-nucleon center-of-momentum system. Both hadrons could be identified. Some results from this work were published earlier. This paper describes properties of the apparatus, data on the two-particle correlation as a function of the kinematic variables and quantum numbers of the produced hadrons, invariant two-particle cross sections, and scaling properties of symmetric hadron-pair production.

ABSTRACT: A new type of hadron calorimeter is described which measures the energy of ahadronby detecting the Cherenkov light produced by the hadronic shower it initiates in a large tank of water. The device features large aperture with good uniformity, good energy containment, andmodest resolution at modest cost. The response was studied as a function of particle type and momentum. Resolution of 40% (RMS) has been achieved at 20 GeV.

ABSTRACT: The properties of the dimuon enhancement seen in 400-GeV proton-nucleus collisions have been clarified by a threefold increase in data. We find two peaks whose widths are consistent with our resolution: M/sub 1/ = 9.4 GeV with dsigma/dy vertical-bar /sub y/ = 1.8 x 10/sup -37/ cm/sup 2//nucleon and M/sub 2/ = 10.0 GeV with Bdsigma/dy vertical-bar /sub y/ = 0.7 x 10/sup -37/ cm/sup 2//nucleon. Evidence for the possible existence of a third peak near 10.4 GeV is discussed as are the comparison with the properties of a qq-bar system, where q is a new heavy quark.

ABSTRACT: The properties of the dimuon enhancement seen in 400-GeV proton-nucleus
collisions have been clarified by a threefold increase in data. We find
two peaks whose widths are consistent with our resolution:
M1=9.4 GeV with B
dσdy|y=0=1.8×10-37
cm2/nucleon and M2=10.0 GeV with B
dσdy|y=0=0.7×10-37
cm2/nucleon. Evidence for the possible existence of a third
peak near 10.4 GeV is discussed as are the comparisons with the
properties of a qq¯ system, where q is a new heavy quark.
