[en] The aim of this review is to summarize the recent progress in the field of elastic scattering and total cross section in this new energy domain. In Section 2 a survey of the experimental situation is outlined. The most significant data are presented, with emphasis on the interpretation, not the specific details or technicalities. This section is therefore intended to give a self-contained look at the field, especially for the nonspecialist. In Section 3, hadron scattering at high energy is described in an impact parameter picture, which provides a model-independent intuitive geometrical representation. The diffractive character of elastic scattering, seen as the shadow of inelastic absorption, is presented as a consequence of unitarity in the s-channel. Spins are neglected throughout this review, inasmuch as the asymptotic behavior in the very high-energy limit is the main concern here. In Section 4 some relevant theorems are recalled on the limiting behavior of hadron-scattering amplitudes at infinite energy. There is also a brief discussion on how asymptotically rising total cross sections imply scaling properties in the elastic differential cross sections. A quick survey of eikonal models is presented and their predictions are compared with ISR and SPS Collider data

[en] At the beginning of September 1950, while on a short vacation in Italy with his family, Bruno Pontecorvo suddenly disappeared. Nobody knew of him until 4 March 1955, when he gave a press conference in Moscow at the Academy of Sciences where he explained the motivations that had led him to decide to live in Russia. He arrived in Moscow in September 1950 and at the end of October of the same year he moved in Dubna and started his research work at the Institute of Nuclear Problems where, at the time, the most powerful particle accelerator in the world was in operation. A historical reconstruction of the early years of his scientific activity is done through the pages of his first logbook. This “laboratory notebook”, dated November 1, 1950, contains unpublished notes, ideas and considerations that Bruno wrote by hand, mostly in English, at the beginning of his work in Russia.

[en] Correlations between charged particles and a photon emitted at intermediate and large angles are presented as a function of the transverse momentum of the photon. The correlation function between charged secondaries and a particle (π^-, K^-, antiproton, or n) produced in the fragmentation region is also investigated

[en] The different experimental techniques used so far to measure the proton-proton and proton-antiproton total cross sections at high energies are discussed and the many and subtle difficulties often arising in these measurements, are pointed out. (author). 29 refs.; 12 figs

[en] The successful cooling technique of antiproton beams at CERN has recently allowed the acceleration of proton and antiproton bunches simultaneously circulating in opposite directions in the SPS. Hadron-hadron collisions could so be produced at a centre-of-mass energy one order of magnitude higher than previously available, thus opening a new wide range of energies to experimentation. This technique also made it possible to replace one of the two proton beams in the ISR by a beam of antiprotons, allowing a direct precise comparison, by the same detectors, of pp and anti pp processes at the same energies. The recent results are summarized of the forward elastic scattering and total cross-section in this new energy domain. (Mori, K.)

[en] Data from the CERN, ISR, and SPS are reviewed. Total and differential cross sections as a function of energy are reported for proton--proton and antiproton--proton interactions

[en] A study has been made of the properties of the SGS/sup 1/ D779 based readout electronics for limited streamer tubes, both with pulses from a pulse generator and with strip pulses from the actual chambers to be used in the SLD detector. To accommodate the special requirements of the SLD detector, a new hybrid circuit has also been developed and tested, which is capable of operating with pulses from the strips of tubes operated below the limited streamer mode voltages

[en] A FASTBUS slave module has been built for the acquisition and preliminary online elaboration of digital data coming from limited streamer tube strip readout electronics. The module, based on the Motorola MC68020 microprocessor, performs fast readout with zero suppression, cluster searching and monitoring of the apparatus. (author). 4 refs, 3 figs

[en] The front-end digital electronics and the Fastbus readout and data reduction module for limited streamer tube strips of the SLD warm iron calorimeter and muon tracker are described. A special high-sensitivity front-end hybrid has been developed to read strip information from limited streamer tubes working well below the limited streamer voltages. An MC68020-based Fastbus module to perform fast readout, zero suppression, cluster searching and apparatus monitoring has also been designed, built and tested. (orig.)
