Prospectives de recherche du quark de quatrième génération u4 avec le détecteur ATLAS auprès du LHC

Abstract : The Standard Model describes the particle physics world and all measurements confirm its validity. However some problems are not solved by this model and numerous extensions of this model have been proposed. One of them postulate the existence of a fourth family of fermions in addition to the three standard families forming the building block of the Standard Model. This study, made in the ATLAS experiment at LHC, describes some methods which permit to discover a fourth generation up quark u4 pair produced decaying semi-leptonically. Jet energy scale and the jet energy resolution measurement are primarily presented because of their interest in this precise measurement. A method to discover the u4 quark and the evaluation of the discovery potential are then presented in details. Finally, a measurement of the mass of this quark is realized assuming the fact that it has been discovered.
