Abstract
The ATLAS detector is designed to exploit the full physics potential in the TeV energy region opened up by the Large Hadron Collider at a center of mass energy of 14 TeV with very high luminosities. The physics performance of the ATLAS detector on Higgs, extra-dimension and strong symmetry breaking scenario is summarized in this note. ATLAS experiment has great discovery potential for these new phenomena with high luminosity. Triple gauge couplings are very sensitive for probing new physics at TeV scale. We show that ATLAS can measure these couplings very precisely with high luminosity.
Highlights
The Large Hadron Collider (LHC), under construction at CERN, will collide protons at a center-of-mass energy of 14 TeV with very high luminosities of 1033 − 1034 cm−2s−1
We present below examples of the experimental signatures of direct or virtual production of gravitons, that can be detected by ATLAS at the LHC
It can be seen that a tenfold luminosity increase at the SLHC should extend the sensitivity for the λ-type and g1Z parameters into the range of ∼ 10−3 expected from the radiative corrections in the Standard Model (SM), and should allow a meaningful test of these corrections and others that arise for example in supersymmetric models
Summary
The Large Hadron Collider (LHC), under construction at CERN, will collide protons at a center-of-mass energy of 14 TeV with very high luminosities of 1033 − 1034 cm−2s−1. There is an upgrade plan to operate the LHC with a luminosity of 1035 cm−2s−1. ATLAS is one of the largest and most elaborate detectors for high energy physics ever designed. Each component of the detector is briefly summarized below: 1. Superconducting magnets: a) Solenoid: provides a 2 T magnetic field for the inner detectors in a cylinder of length 6.80 m and diameter 2.30 m Each component of the detector is briefly summarized below: 1.
