Abstract
Abstract: This paper discusses some of the problems of triggering at a high energy, high luminosity pp collider. A suggested second level track trigger for the ATLAS detector is described, based on hit information from a silicon tracker. Detailed Monte Carlo simulations have been performed to assess the performance of the trigger in accepting electrons and in rejecting the QCD jets that would fake electrons in the first level calorimeter trigger. Studies of the feasibility of implementing such a trigger are also presented.

A suggested second level track trigger for the ATLAS detector is described, based on hit information from a silicon tracker. Detailed Monte Carlo simulations have been performed to assess the performance of the trigger in accepting electrons and in rejecting the QCD jets that would fake electrons in the first level calorimeter trigger. Studies of the feasibility of implementing such a trigger are also presented.</abstract><relatedItem type="host"><titleInfo><title>Nuclear Inst. and Methods in Physics Research, A</title></titleInfo><titleInfo type="abbreviated"><title>NIMA</title></titleInfo><genre type="journal" authority="ISTEX" authorityURI="https://publication-type.data.istex.fr" valueURI="https://publication-type.data.istex.fr/ark:/67375/JMC-0GLKJH51-B">journal</genre><originInfo><publisher>ELSEVIER</publisher><dateIssued encoding="w3cdtf">19931115</dateIssued></originInfo><identifier type="ISSN">0168-9002</identifier><identifier type="PII">S0168-9002(00)X0420-2</identifier><part><date>19931115</date><detail type="volume"><number>336</number><caption>vol.</caption></detail><detail type="issue"><number>1–2</number><caption>no.</caption></detail><extent unit="issue-pages"><start>1</start><end>389</end></extent><extent unit="pages"><start>59</start><end>77</end></extent></part></relatedItem><identifier type="istex">620F2CDB2B4BF82ACE9826EC7F09D174ABD07F49</identifier><identifier type="ark">ark:/67375/6H6-VCNHZB52-M</identifier><identifier type="DOI">10.1016/0168-9002(93)91080-7</identifier><identifier type="PII">0168-9002(93)91080-7</identifier><recordInfo><recordContentSource authority="ISTEX" authorityURI="https://loaded-corpus.data.istex.fr" valueURI="https://loaded-corpus.data.istex.fr/ark:/67375/XBH-HKKZVM7B-M">elsevier</recordContentSource></recordInfo></mods><json:item><extension>json</extension><original>false</original><mimetype>application/json</mimetype><uri>https://api.istex.fr/document/620F2CDB2B4BF82ACE9826EC7F09D174ABD07F49/metadata/json</uri></json:item></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
