Multiplicity of sets of soft jets with energies ranging in some interval is determined. The possible role of collective effects is discussed. The phenomenon of jet emission is well known in QCD and firmly established in experiment. The two-jet events in e + e −-annihilation provide us with unique possibility to measure jets with fixed energy equal to that of colliding particles. In all other ca...

The jets of GRS 1915+105 carry a considerable energy away from the central source into the ISM. The similarity of the jets of this source and jets in radio galaxies or radio-loud quasars suggests that we should detect large-scale, synchrotron emitting radio structures surrounding GRS 1915+105. However, these large structures have not been found. We show that by adapting a model for the radio lo...

The large-scale motions of planetary atmospheres and oceans, constrained by strong stable stratification and rapid rotation, are characterized in part by quasi-two dimensional turbulent motion and in part by coherent structures, such as vortices, zonal jets, and low-frequency waves. These motions are intimately linked and understanding their complex and multiscale interactions presents a comple...

The observational evidence for jets and phenomena arising from rotation powered radio pulsars is reviewed, including many recent and exciting discoveries at X-ray wavelengths. The well studied jets of the Crab pulsar are summarised, including recent results from the HST. The evolutionary links between the known binary radio pulsars and jets sources in X-ray binaries are discussed.

This paper reviews several aspects of liquid jet impingement cooling, focusing on research done in our lab at MIT. Free surface, circular liquid jet are considered. Theoretical and experimental results for the laminar stagnation zone are summarized. Turbulence effects are discussed, including correlations for the stagnation zone Nusselt number. Analytical results for downstream heat transfer in...

We search for anomalous production of heavy-flavor quark jets in association with W bosons at the Fermilab Tevatron pp Collider in final states in which the heavy-flavor quark content is enhanced by requiring at least one tagged jet in an event. Jets are tagged using one algorithm based on semileptonic decays of b/c hadrons, and another on their lifetimes. We compare e+jets (164 pb(-1)) and mu+...

A measurement of jet shapes in top-quark pair events using 1.8 fb −1 of √ s = 7 TeV pp collision data recorded by the ATLAS detector at the LHC is presented. Samples of top-quark pair events are selected in both the single-lepton and dilepton final states. The differential and integrated shapes of the jets initiated by bottom-quarks from the top-quark decays are compared with those of the jets ...

As the LHC prepares to start taking data, this review is intended to provide a QCD theorist’s understanding and views on jet finding at hadron colliders, including recent developments. My hope is that it will serve both as a primer for the newcomer to jets and as a quick reference for those with some experience of the subject. It is devoted to the questions of how one defines jets, how jets rel...
