Tesis doctoral de Matteo Volpi
The thesis is focused on the studies of the inclusive inelastic production of the charged particles at the lhc collider that operates at the frontier center-of-mass energy of 7tev. The analyzed data correspond to about sixteen inverse micro-barn of the very first integrated luminosity collected by the atlas detector by the beginning of 2010. Having fully taken advantage of above factors, scrupulous studies performed in the thesis resulted in the measurements of the charged particles inclusive production cross-sections that were compared to the variety of popular phenomenological models of the soft qcd. The results reported in the thesis constitute a novel data sample corresponding to a new kinematic qcd region. Thus, the mild (10-20)% disagreement between the data and the predictions of different phenomenological models came as no surprise. The reported results were used to adjust existing soft qcd models to adequately reproduce the busy hadronic environment present in the lhc collisions, thus reinforcing current theoretical framework. The type of the studies presented in the thesis belongs to a well established research line in the field of high energy physic (hep) that consists of full re-discovery of the standard model in the environment of new collider experiment before attempting to move further. Studies presented in the thesis have already led to one publication in the leading high energy physics journal, plb (march 2010), and another paper is in preparation. I took an important role in this, very first publication of the atlas results, often considered as an informal criteria for the phd thesis merits inside of the hep community. additional strong points of the work presented in the thesis may be summarized as following: 1) very well structured and focused presentation of the studies performed. 2) meticulous following of the analysis canons adopted in the hep community. 3) appropriate usage of the most up-to-date soft qcd simulations. 4) careful studies of the impact of the detector conditions and trigger selection efficiency on the results. 5) careful evaluation of the systematic errors on the reported cross-sections and distributions.
