DOWNLOAD EBOOKThis thesis, which won one of the six 2015 ATLAS Thesis Awards, concerns the study of the charmonium and bottomonium bound heavy quark bound states. The first section of the thesis describes the observation of a candidate for the chi_b(3P) bottomonium states. This represented the first observation of a new particle at the LHC and its existence was subsequently confirmed by D0 and LHCb experiments. The second part of the thesis presents measurements of the prompt and non-prompt production of the chi_c1 and chi_c2 charmonium states in proton-proton collisions. These measurements are compared to several theoretical predictions and can be used to inform the development of theoretical models of quarkonium production.

DOWNLOAD EBOOKThese proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in leptonproton scattering.

DOWNLOAD EBOOKThe authors present results of a new measurement of the inclusive b quark fragmentation function in Z decays using a novel kinematic B hadron energy reconstruction technique. The measurement is performed using 150,000 hadronic Z events recorded in the SLD experiment at SLAC between 1996 and 1997. The small and stable SLC beam spot and the CCD-based vertex detector are used to reconstruct topological B-decay vertices with high efficiency and purity, and to provide precise measurements of the kinematic quantities used in this technique. The authors measure the B energy with good efficiency and resolution over the full kinematic range. While comparing the scaled B energy distribution with predictions of several models of b quark fragmentation, the authors also test several functional forms of the B energy distribution. Several fragmentation models and functional forms are excluded by the data. The mean of the scaled energy distribution of the weakly decaying B hadron is measured to be x{sub B} = 0.714"0.00(stat)"0.007(syst)"0.002 (model).

DOWNLOAD EBOOKWe present a measurement of the b-quark inclusive fragmentation function in Z° decays using a novel kinematic B-hadron energy reconstruction technique. The measurement was performed using 350,000 hadronic Z° events recorded in the SLD experiment at SLAC between 1997 and 1998. The small and stable SLC beam spot and the CCD-based vertex detector were used to reconstruct B-decay vertices with high efficiency and purity, and to provide precise measurements of the kinematic quantities used in this technique. We measured the B energy with good efficiency and resolution over the full kinematic range. We compared the scaled B-hadron energy distribution with models of b-quark fragmentation and with several ad hoc functional forms. A number of models and functions are excluded by the data. The average scaled energy of weakly-decaying B hadrons was measured to be x{sub b} = 0.709 " 0.003 (stat) " 0.003 (syst) " 0.002 (model).
