ALICE: Physics performance report, volume II

2006

ALICE is a general-purpose heavy-ion experiment designed to study the physics of strongly interacting matter and the quark-gluon plasma in nucleus-nucleus collisions at the LHC. It currently involves more than 900 physicists and senior engineers, from both the nuclear and high-energy physics sectors, from over 90 institutions in about 30 countries. The ALICE detector is designed to cope with the highest particle multiplicities above those anticipated for Pb-Pb collisions (dN(ch)/dy up to 8000) and it will be operational at the start-up of the LHC. In addition to heavy systems, the ALICE Collaboration will study collisions of lower-mass ions, which are a means of varying the energy density, …

A search for quarks in the CERN SPS neutrino beam

1978

Quarks and leptons are the only pointlike particles known so far. However, a search for a proton-breaking mechanism in high-energy neutrino-nucleon interactions had never been performed. We present here the results of the first experiment in this field.

Evidence of the same multiparticle production mechanism in p−p collisions as in e+e− annihilation

1980

The split-field magnet spectrometer at the CERN intersecting storage rings was used to measure, in p-p collisions at square root s=62 GeV, the inclusive momentum distribution of the charged particles produced in the same hemisphere as the leading proton (x>0.4). A new scaling variable was introduced in order to take into account baryon-number conservation effects in p-p interactions. It is shown that distributions in this variable are in good agreement with the momentum distribution of the hadrons produced in e/sup +/e/sup -/ annihilation. The results suggest that the multiparticle production mechanism in p-p collisions is the same as in e/sup +/e/sup -/ provided that the effects of baryon-…
