The contributions of the PLUTO experiment to e exp + e exp - physics at collision energies in the range of 3-31 GeV are reviewed. The review briefly sketches the storage rings DORIS and PETRA at DESY, and describes the most important features of the PLUTO detector, of data processing, and of the analysis methods. It covers the physics results in the fields of electroweak interactions, of the heavy lepton tau and the search for still heavier leptons, of hadron production with evidence for quark and gluon jets, as well as multiparton effects, of UPSILON decays and their relation to QCD, and concludes with first results in high-energy photon-photon interactions.

The fact that ISABELLE is designed to operate over the energy range 30 + 30GeV to 200 + 200GeV is pointed out for clarification of the capabilities of ISABELLE. (s is the square of the center-of-mass total energy.).

The calibration of ATLAS barrel calorimeters (including pre shower system, electromagnetic Liquid Argon calorimeter and scintillating hadron tile calorimeter) was done by standard calibration and weighting technique approaches. The standard calibration gives the bad linearity for hadron non compensated calorimeter. The calibration with weighting technique, in comparison with standard calibration, restores linearity and improves energy resolution up to ((sigma)/E)(sup 2) = (38.6%/(radical)E)(sup 2) + (1.5%)(sup 2) for (eta) 0.6. 6 refs., 4 figs., 1 tab.

A large multi-cell threshold gas Cerenkov counter consisting of 78 cells has been built for use in a high energy muon scattering experiment at CERN (European Muon Collaboration). It is used with neon, nitrogen or a mixture of those two gases, allowing the pion threshold to be varied between 6 and 20 GeV/c. The sensitive region of the counter has a length of 4.0 m and entrance and exit windows of 1.1 x 2.4 m exp 2 and 2.4 x 5.0 m exp 2 , respectively. (Atomindex citation 12:602542)

A review is presented of the colliding beam facilities in existence today. The major high energy physics facilities around the world are described, and a view is presented of the beam collisions in which the instruments used to make the beams collide and those used to detect the products of particle interactions in the beam overlap region are described.

This report describes a computer program (developed for analysis of Bevalac data) that calculates stopping power, range, or energy, and which includes the necessary corrections for accuracy in the high Z sub 1 , beta regime, as discussed in the theoretical and review papers of S.P. Ahlen. The program is also available on PSS at LBL's Computer Center. (ERA citation 05:017131)

A complete amplitude analysis of experimental data on pi N scattering in (S,t) and (S,b) representations in the energy interval from 6 to 200 GeV is carried out. It is shown that in pi N scattering at superhigh energies a non-zero polarization of final nucleon independent on the incident pion energy and sign must exist. Profile function of pi N scattering resembles that of a scattering of a ''grey ball'' whose transparency and radius first increase as the energy grows, and then become constant. The mean-square radius at high-energy interaction is almost constant and is equal to 0.75 fermi. A shell structure of pi N scattering at 6 GeV is found. (Atomindex citation 11:567721)

This report covers recent completed work, work in progress, and plans for the future developed during the period July 1, 1980 to July 1, 1981. It describes two main activities, those in connection with experiments carried out at LAMPF and devoted to studies of high momentum phenomena in nuclei and those carried out at CERN devoted to ultrarelativistic nuclear-nuclear collisions.
