Hot Paper in Physics

“Observation of a New Boson at a Mass of 125 Gev with the CMS Collaboration at CERN,” by the CMS Collaboration, Physics Letters B, 716(1): 30-61, 17 September 2012. 

Abstract: “Results are presented from searches for the standard model Higgs boson in proton-proton collisions at root s = 7 and 8 TeV in the Compact Muon Solenoid experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 fb(-1) at 7 TeV and 5.3 fb(-1) at 8 TeV. The search is performed in five decay modes: gamma gamma, ZZ, W+W-, tau(+)tau(-), and b (b) over bar. An excess of events is observed above the expected background, with a local significance of 5.0 standard deviations, at a mass near 125 GeV, signalling the production of a new particle. The expected significance for a standard model Higgs boson of that mass is 5.8 standard deviations. The excess is most significant in the two decay modes with the best mass resolution, gamma gamma and ZZ; a fit to these signals gives a mass of 125.3 +/- 0.4(stat.) +/- 0.5(syst.) GeV. The decay to two photons indicates that the new particle is a boson with spin different from one.”

This 2012 report from Physics Letters B, representing the work of thousands of coauthors at the CMS Collaboration at CERN, was cited 200 times in current journal articles indexed by Thomson Reuters during July-August 2013. During that two-month period, only one physics paper surpassed it in citations: a report published in the same journal issue, also documenting the successful effort to confirm the Higgs boson. (The latter report, from another of CERN’s multi-thousand-author collectives, the LHC Collaboration, was previously highlighted as a Hot Paper based on an earlier bimonthly citation tally; for the present July-August count, it barely edged the CMS Collaboration report, with 204 citations). Prior to the most recent bimonthly tally, citations to the CMS paper have accrued as follows, as tracked by Essential Science Indicators Hot Papers:

May-June 2013: 126 citations
March-April 2013: 158
January-February 2013: 79
November-December 2012: 49

Total citations to date: 612
