Fermilab Tevatron and upgrade status
No full textPerformance and performance limitations of the Tevatron proton-antiproton collider at Fermilab will be discussed along with plans for improving the performance by a factor of five by the end of the decade. The centerpiece of this effort is the Fermilab Main Injector, a new 150 GeV synchrotron now under construction. Status of the project will be presented
Slow proton and Delta /sup ++/ production in K/sup +/p interactions at 70 GeV/c
No full textThe inclusive inelastic processes K/sup +/p to pX/sup +/ and K/sup +/p to Delta /sup ++/X/sup 0/ are studied in an incident momentum of 70 Ge V/C. The data comes from the Big European Bubble Chamber BEBC filled with hydrogen, exposed to an rf separated K/sup +/ beam at the CERN SPS accelerator. The inclusive cross section is measured for protons with laboratory momentum p/sub LAB/<or approximately=1.2 GeV/c. Comparisons are made with other K/sup +/p data and with pp data at 69 GeV/c. Evidence is found for Pomeron exchange at the beam vertex both for slow proton and Delta /sup ++/-production as well as for absorptive pion exchange at the (p, Delta /sup ++/) vertex. (11 refs)

Inclusive neutral kaon production in 70 GeV/c Kp interactions
No full textThe inclusive production of neutral kaons in 70 GeV/c K/sup +/p interactions is studied with the CERN BEBC bubble chamber. The (semi-) inclusive cross sections are interpreted in terms of the various strangeness channels leading to neutral kaon production. The invariant inclusive cross section for kaon production is studied as a function of p/sub t//sup 2/ and the Feynman variable x. The latter distributions are considered both 'raw' and corrected for the presence of K/sup 0/'s resulting from K* decay. They are compared with the prediction expected from the Regge-Mueller formalism, the recombination model and fragmentation models. (24 refs)
