This thesis, which received one of many six 2015 ATLAS Thesis Awards, matters the research of the charmonium and bottomonium sure heavy quark sure states. the 1st part of the thesis describes the remark of a candidate for the chi_b(3P) bottomonium states. This represented the 1st statement of a brand new particle on the LHC and its lifestyles was once thus proven via D0 and LHCb experiments. the second one a part of the thesis offers measurements of the recommended and non-prompt construction of the chi_c1 and chi_c2 charmonium states in proton-proton collisions. those measurements are in comparison to numerous theoretical predictions and will be used to notify the advance of theoretical versions of quarkonium creation.

Example text

The LHC is also capable of accelerating lead (Pb) ions to deliver both lead-lead and proton-lead collisions. The LHC has four interactions points (IP), shown in Fig. 1, each instrumented with a modern particle physics experiment. The ATLAS and CMS general purpose experiments are designed for high-luminosity operation (up to 1034 cm−2 s−1 ) and are equipped to study a wide range of phenomena. Their physics goals include Higgs boson searches (and measurements), searches for super-symmetric particles and exotic phenomena and measurements of the standard model.
