This thesis relies at the first information from the massive Hadron Collider (LHC) at CERN. Its topic may be defined because the classical Rutherford scattering test tailored to the LHC: dimension of scattering angles to look for brand new physics and substructure. on the LHC, colliding quarks and gluons go out the proton collisions as collimated particle showers, or jets. The thesis offers reviews of the scattering angles of those jets. It incorporates a phenomenological research on the LHC layout strength of 14 TeV, the place a version of so-called huge additional dimensions is used as a benchmark procedure for the sensitivity to new physics.
The experimental result's the 1st size, made in 2010, by means of ATLAS, working on the LHC start-up power of seven TeV. the result's appropriate with the normal version and demonstrates how good the physics and the gear are understood. the 1st info is a tiny fraction of what's going to be amassed within the coming years, and this research has set the level for appearing those measurements with self assurance because the LHC accumulates luminosity and raises its power, thereby probing smaller size scales.
