The global topologies of three- and four-jet events produced in {bar p}p interactions are described. the three- and four-jet events are selected from data recorded by the D0 detector at the Tevatron Collider operating at a center-of-mass energy of (square root)s = 1800 GeV. the measured normalized distributions of various topological variables are compared with parton-level predictions of the tree- level QCD calculations. The parton-level QCD calculations are found to be in good agreement with the data. The studies also show that the topological distributions of the different subprocesses involving different numbers of quarks are very similar and reproduce the measured distributions well.

We describe studies of jet production in {bar p}p collisions at (square root)s = 1.8 TeV. We have investigated topological distributions in inclusive three and four-jet events and find them to be well- described by tree-level QCD matrix elements and also by the HERWIG Monte Carlo. We have measured the ratio of inclusive three-jet to two- jet cross sections as a function of summed jet transverse energy. This is found to be in good qualitative agreement with QCD; the data show some preference for a softer renormalization scale for emission of the third jet.

Abstract: The algorithms used by the ATLAS Collaboration during Run 2 of the Large Hadron Collider to identify jets containing b-hadrons are presented. The performance of the algorithms is evaluated in the simulation and the efficiency with which these algorithms identify jets containing b-hadrons is measured in collision data. The measurement uses a likelihood-based method in a sample highly enriched in tt ̄ events. The topology of the t→Wb decays is exploited to simultaneously measure both the jet flavour composition of the sample and the efficiency in a transverse momentum range from 20 to 600 GeV. The efficiency measurement is subsequently compared with that predicted by the simulation. The data used in this measurement, corresponding to a total integrated luminosity of 80.5 fb−1, were collected in proton-proton collisions during the years 2015-2017 at a centre-of-mass energy s√= 13 TeV. By simultaneously extracting both the efficiency and jet flavour composition, this measurement significantly improves the precision compared to previous results, with uncertainties ranging from 1 to 8% depending on the jet transverse momentum

Kinematic properties of four jet events taken during the 1988/89 run of the Tevatron at Fermilab are compared with the predictions of a leading order QCD calculation. Preliminary work on a search for double parton scattering is presented.
