Abstract

An attempt at the direct observation of the cascade decay of beauty particles, produced by π⁻ of 350 GeV/c leading to 3 muons or 4 muons in the final state, has been made in an emulsion/counter hybrid experiment at CERN. Under the assumption that the lifetime of beauty particles is of the order of 10⁻¹³s the non-observation of any candidates provides an upper limit for beauty production of ∼90 nb at the 90% confidence level.

Physics with hadron and photon beams at the SPS
2004, Physics Reports
This report attempts to cover the physics results obtained in the last 25 years by some 70 SPS experiments. A variety of beams, pion, kaon, proton, antiproton, hyperon and photon were used in these experiments, and, in one case (UA6), the p and $\bar{p}$ beams stored in the SPS Collider were made to hit an internal gas jet target. The panoply of detection techniques employed was also very large, from bubble chambers to silicon microdetectors, and the physics issues addressed ranged from hard to ultrasoft processes. The available space however, will only allow to touch briefly a few amongst the many interesting results which have been published since 1979.
In what follows, we shall try to group the experiments under four headings:
(1) Hard scattering, (2) Heavy flavours, (3) Spectroscopy, (4) Soft processes.

Computer aided digitized microscope (CADIM) for nuclear emulsion analysis
1984, Nuclear Instruments and Methods In Physics Research
The CADIM apparatus is a combination of : (a) a microscope equipped with a motorized stage and a drawing attachment; (b) high precision digitizers of X, Y and Z coordinates; (c) television camera, monitors and tape recorder; (d) a microcomputer and its peripherals. In addition to fast scanning and measurements in nuclear emulsion, it enables the performing of a direct visual comparison between the topology of an event seen in emulsion and its reconstructed topology from the data taken by associated electronic detectors. The use of television techniques allows image display and storing. This apparatus will be used in the first place for the CERN hybrid experiment WA71 searching for beauty particles.
