Neutralino decays at the CERN LHC
We study the distribution of lepton pairs from the second lightest neutralino decay χ̃2 → χ̃1ll. This decay mode is important to measure the mass difference between χ̃2 and the lightest neutralino χ̃ 0 1, which helps to determine the parameters of the minimal supersymmetric standard model at the CERN LHC. We found that the decay distribution strongly depends on the values of underlying MSSM paramet...
متن کاملPossible Accelerators @ CERN Beyond the LHC
The physics and world-wide accelerator context for possible accelerator projects at CERN after the LHC are reviewed, including the expectation that an ee linear collider in the TeV energy range will be built elsewhere. Emphasis is laid on the Higgs boson, supersymmetry and neutrino oscillations as benchmarks for physics after the LHC. The default option for CERN’s next major project may be the ...
متن کاملBosonic quartic couplings at CERN LHC
We analyze the potential of the CERN Large Hadron Collider to study anomalous quartic vector-boson interactions ZZgg , ZZZg , WWgg , and WWZg through the weak boson fusion processes qq →qqgg and qq→qqgZ(→,1,2) with ,5e or m . After a careful study of the backgrounds and how to extract them from the data, we show that the process pp→ j jg,, is potentially the most sensitive to deviations from th...
متن کاملThe CMS experiment at the CERN LHC
The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and leadlead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 1034 cm−2s−1 (1027 cm−2s−1). At the core of the CMS detector sits a high-magneticfield and large-bore superconducting sol...
متن کاملnon-corrective approach to pronunciation
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
