We are interested in the characteristics of hadron production outside the identified jet cones. We improve earlier definitions and introduce surrounding rings/belts around the cone of identified jets. In this way even multiple jet events can be studied in details. We define the underlying event as collected hadrons from outside jet cones and outside surrounding belts, and investigate the features of these hadrons. We use a PYTHIA generated data sample of proton-proton collisions at s = (7 TeV)^2. This data sample is analysed by our new method and the widely applied CDF method. Angular correlations and momentum distributions have been studied and the obtained results are compared and discussed.", "revisions": [ { "version": "v1", "updated": "2011-04-05T09:43:49.000Z" } ], "analyses": { "keywords": [ "lhc energies", "underlying event", "proton-proton collisions", "multiple jet events", "identified jet" ], "tags": [ "journal article" ], "publication": { "doi": "10.1051/epjconf/20111304006" }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "inspire": 894972, "adsabs": "2011EPJWC..1304006A" } } }
