Abstract (data abstract)
Fermilab-Tevatron. Measurement of the cross section for UPSILON(1S) production in PBAR P collisions at a centre of mass energy of 1.96 TeV. The data are collected using the UPSI --& gt; MU+ MU- decay mode from a sample of 159 +- 10 pb-1.. This record contains the updated cross sections from the erratum due to an increase in the integrated luminosity.
