Shape, transverse size, and charged hadron multiplicity of jets in pp collisions at √s=7 TeV

Open Access: This article is distributed under the terms of the Creative Commons Attribution License.-- CMS Collaboration: et al.Measurements of jet characteristics from inclusive jet production in proton-proton collisions at a centre-of-mass energy of 7 TeV are presented. The data sample was collected with the CMS detector at the LHC during 2010 and corresponds to an integrated luminosity of 36 inverse picobarns. The mean charged hadron multiplicity, the differential and integral jet shape distributions, and two independent moments of the shape distributions are measured as functions of the jet transverse momentum for jets reconstructed with the anti-kT algorithm. The measured observables are corrected to the particle level and compared with predictions from various QCD Monte Carlo generators.European Commission; Federal Ministry of Science, Research and Economy (Austria); National Fund for Scientific Research (Belgium); Research Foundation – Flanders; Conselho Nacional de Desenvolvimento Científico e Tecnológico (Brasil); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Brasil); Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro; Fundação de Amparo à Pesquisa do Estado de São Paulo; Bulgarian Ministry of Education and Science; Centre National de la Recherche Scientifique (France); Commissariat à l'énergie atomique et aux énergies alternatives (France); Ministry of Science and Technology of the People's Republic of China; Chinese Academy of Sciences; National Natural Science Foundation of China; Colciencias (Colombia); Croatian Ministry of Science, Education and Sport; Academy of Finland; Helsinki Institute of Physics; Bundesministerium für Bildung und Forschung (Deutschland); Deutsche Forschungsgemeinschaft; Helmholtz Association; General Secretariat of Research and Technology (Greece); Hungarian Scientific Research Fund; National Office for Research and Technology (Hungary); Department of Atomic Energy (India); Department of Science and Technology (India); Council of Science and Industrial Research (India); Institute for Research in Fundamental Sciences (Iran); Science Foundation Ireland; Istituto Nazionale di Fisica Nucleare (Italia); Korean Ministry of Education, Science and Technology; Lithuanian Academy of Sciences; Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional (México); Consejo Nacional de Ciencia y Tecnología (México); Secretaría de Educación Pública (México); Universidad Autónoma de San Luis Potosí; Ministry of Science and Innovation (New Zealand); Ministry of Science and Higher Education and the National Science Centre (Poland); Fundação para a Ciência e a Tecnologia (Portugal); Joint Institute for Nuclear Research (Russia); Russian Academy of Sciences; Russian Foundation for Basic Research; Ministry of Education, Science and Technological Development (Serbia); Ministerio de Ciencia e Innovación (España); Swiss Funding Agencies; Swiss National Science Foundation; National Science Council (Taiwan); The Scientific and Technological Research Council of Turkey; Turkish Atomic Energy Authority; Science and Technology Facilities Council (UK); Department of Energy (US); National Science Foundation (US); A.
