Measurement of double parton scattering in pp collisons at s

Published

Journal Article

A strong signal for double parton scattering (DP) is observed in a 16 pb−1 sample of pp → γ + 3 jets + X data from the CDF experiment at the Fermilab Tevatron. The process-independent DP parameter, σ eff, is obtained without reference to theoretical calculations by comparing observed DP events to events with hard scatterings at separate pp collisons. The result, σ eff = (14.5 ± 1.7 +1.7−2.3)mb, represents a significant improvement over previous measurements. For the first time, the Feynman x dependence of the σeff parameter is investigated, and no dependence is seen. © 1997 The American Physical Society.
