Distributions of topological observables in inclusive three- and four-jet events in pp collisions at root s=7 TeV

WOS: 000357123400006 ; This paper presents distributions of topological observables in inclusive three- and four-jet events produced in pp collisions at a centre-of-mass energy of 7 TeV with a data sample collected by the CMS experiment corresponding to a luminosity of 5.1 fb(-1). The distributions are corrected for detector effects, and compared with several event generators based on two- and multi-parton matrix elements at leading order. Among the considered calculations, MadGraph interfaced with PYTHIA6 displays the overall best agreement with data. ; European Union, Regional Development FundEuropean Union (EU); Compagnia di San Paolo (Torino)Compagnia di San Paolo; Consorzio per la Fisica (Trieste); MIUR (Italy)Ministry of Education, Universities and Research (MIUR) [20108T4XTM]; Thalis programme; Aristeia programme; EU-ESFEuropean Union (EU); Greek NSRFGreek Ministry of Development-GSRT; National Priorities Research Program by Qatar National Research Fund ; We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort. In addition, we gratefully acknowledge the computing centres and personnel of the Worldwide LHC Computing Grid for delivering so effectively the computing infrastructure essential to our analyses.; r Finally, we acknowledge the enduring support for the construction and operation of the LHC and the CMS detector provided by the following funding agencies: the Austrian Federal Ministry of Science, Research and Economy and the Austrian Science Fund; the Belgian Fonds de la Recherche Scientifique, and Fonds voor Wetenschappelijk Onderzoek; the Brazilian Funding Agencies (CNPq, CAPES, FAPERJ, and FAPESP); the Bulgarian Ministry of Education and Science; CERN; the Chinese Academy of Sciences, Ministry of Science and Technology, and National Natural Science Foundation of China; the Colombian Funding Agency ...
