TL;DR: In this paper, a study of events containing at least four high transverse momentum jets and a search for double parton scattering (DPS) have been performed using data collected with the UA2 detector at the CERN p p Collider (√s=630 GeV).

TL;DR: In this paper, a large sample of W→eν events collected by the UA2 experiment at the CERN pp collider between 1988 and 1990 has been used to determine the strong coupling constant α s, from a measurement of the ratio of the production rate of W events with one jet to that with no jets.
