D0 luminosity monitor constant for the 1994-1996 tevatron run
1997
Abstract
The D0 experiment calculates its luminosity using the visible cross section (luminosity monitor constant) {sigma}{sub L0} for its Level 0 trigger based on the world average {anti p}p inelastic cross sections at {radical}s - 1.8 TeV. For the 1992-1993 Tevatron Run (1A), the luminosity monitor constant was determined to be {sigma}{sub L0} = 46. 7{+-}2.5 mb. For the 1994-1996 Tevatron Run (1B/1C), the luminosity monitor constant changed slightly with an upgrade to the electronics in the Level 0 trigger. The luminosity monitor constant becomes on average {sigma}{sub L0} - 44.53 {+-} 2.37 mb for Run 1B/1C. In addition, small corrections for halo and multiple single diffraction are included in integrated luminosity determinations.
