Measurement of the high-mass Drell-Yan cross section and limits on quark-electron compositeness scales
- We present a measurement of the Drell-Yan cross section at high dielectron invariant mass using 120 pb-1 of data collected in pp̄ collisions at √s = 1.8 TeV by the DO Collaboration during 1992-1996. No deviation from standard model expectations is observed. We use the data to set limits on the quark-electron compositeness scale. The 95% confidence level lower limits on the compositeness scale vary between 3.3 and 6.1 TeV depending on the assumed form of the effective contact interaction. © 1999 The American Physical Society.
