Search for the Standard Model Higgs boson with the ATLAS experiment at the LHC leading to the observation of a new particle compatible with the Higgs boson

In 2012 the Large Hadron Collider (LHC), a circular particle collider located beneath the France-Switzerland border, publicly announced the discovery of a new particle with

In conclusion, theoretical arguments and experimental evidence ensure that no particles of the standard model are fakeons, apart from possibly the Higgs boson and the top quark,

The objectives we identified to provide self- and social awareness while learners are practicing in their virtual learning environment are threefold: (1)

Le sujet de cette thèse concerne, en particulier, une contribution à l’étude de dispatching dynamique d’un système énergétique dans un marché libre

d) Distribution of the acoplanarity angle, all other cuts being applied, for the data (trian- gles with error bars) and the Monte Carlo (shadowed histogram). The full line results

During 1997 the ALEPH experiment at LEP gathered 57 pb 1 of data at centre-of- mass energies near 183 GeV. These data are used to look for possible signals from the production of

• The analysis for the lepton pair final state has three improvements: 1) an increased efficiency in the identification of events in which the Higgs boson decays to τ leptons,

Final results of the search for the Standard Model Higgs boson are presented for the data collected by the L3 detector at LEP at centre-of-mass energies up to about 209 GeV.. These
