Abstract
This paper is a summary of the interview-workshop to Aleandro Nisati (12 December 2012, SEMM-Service Enseignement et Multimedia) co-organized by UFR Physique, University of Lille 1, France (Raffaele Pisano, Remi Franckowiak, Bernard Maitte and Lisa Rougetet), ATLAS Experiment Team (CERN, Geneve, Switzerland), in persons of the cited Italian scientist—already Physics coordinator at ATLAS—and his colleague, Steven Goldfarb (CERN-University of Michigan, USA). The latter kindly answered to the questions on the ATLAS detector, LHC machine and CERN-ATLAS laboratories proposed by the participants. Distinguished lectures by historians of science at University of Lille 1 (Bernard Maitte, Bernard Pourprix and Robert Locqueneux) specialist on history of physics opened the workshop session.
Highlights
On July, 4th 2012, the A Toroidal Large Hadron Collider (LHC) ApparatuS (ATLAS) experiment presented a preview of its updated results on the search for the Higgs Boson. (Figure 1)
The results were shown at a seminar held jointly at CERN and via video link at ICHEP, the International Conference for High Energy Physics in Melbourne, Australia (Atlas Collaboration, 2012; Compact Muon Solenoid (CMS) Collaboration, 2012)
At CERN, preliminary results were presented to scientists on site and via webcast to colleagues located in hundreds of institutions around the world
Summary
On July, 4th 2012, the ATLAS experiment presented a preview of its updated results on the search for the Higgs Boson. (Figure 1). The latest results of the search for this particle at the LHC are summarized and discussed, focusing on the recent observation of a new boson by the experiments ATLAS and Compact Muon Solenoid (CMS, the main experiments) at the LHC, with a mass around 126 GeV. PISANO ordinator who had a major role in the discovery and key-note at the Congress This new particle is effetely consistent, within the current available experimental accuracy, with the Standard Model Higgs boson (SMHB). The statistical combination of these results for ATLAS, and independently for CMS, leads to the observation of an excess of events at around 125 GeV mass with at least 5-sigma significance (corresponding to a probability ~4 × 10−7) per experiment Are these results well-matched with historical theoretical theory hypothesed by Higgs last century?. A new extraordinary and exciting era in particle physics just opened up
