Electroweak production of the top quark is measured in pp collisions at sqrt(s) = 7 TeV, using a dataset collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns. With an event selection optimized for t-channel production, two complementary analyses are performed. The first one exploits the special angular properties of the signal, together with background estimates from data. The second approach uses a multivariate analysis technique to probe the compatibility with signal topology expected from electroweak top quark production. The combined measurement of the cross section is 83.6 +/- 29.8 (stat.+syst.) +/- 3.3 (lumi.) pb, consistent with the standard model expectation.

^ 74 GeV and |y| 2.4; the b jets must contain a B hadron. The measurement has significant statistics up to p T ∼ O(TeV). Advanced methods of unfolding are performed to extract the signal. It is found that fixed-order calculations with underlying event describe the measurement well.

This PhD thesis focuses on the search for flavor-changing neutral currents in the decay of a top quark to an up-type quark (q = u, c) and the Standard Model Higgs boson, where the Higgs boson decays to bb. Further, the thesis presents the combination of this search for top quark pair events with other ATLAS searches – in the course of which the most restrictive bounds to date on tqH interactions were obtained. Following on from the discovery of the Higgs boson, it is particularly important to measure the Yukawa couplings of the Standard Model fermions; these parameters may provide crucial insights to help solve the flavor puzzle and may help reveal the presence of new physics before it is directly observed in experiments.

The cross section for the production of single top quarks in the $t$ channel is measured in proton-proton collisions at 13 TeV with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of 2.3 fb$^{-1}$. The event selection requires one muon and two jets where one of the jets is identified as originating from a bottom quark. Several kinematic variables are then combined into a multivariate discriminator to distinguish signal from background events. A fit to the distribution of the discriminating variable yields a total cross section of 232 $\pm$ 13 (stat) $\pm$ 28 (syst) pb and a ratio of top quark and top antiquark production of $R_{t\textrm{-ch.}}= $ 1.81 $\pm$ 0.18 (stat) $\pm$ 0.15 (syst). From the total cross section the absolute value of the CKM matrix element $V_{\mathrm{tb}}$ is calculated to be 1.03 $\pm$ 0.07 (exp) $\pm$ 0.02 (theo). All results are in agreement with the standard model predictions.

Physicians are under increasing pressure to provide quality health care in the most cost-effective way possible. The escalating costs of orthopedic care are driving the need to base clinical decision making on evidence-based data that will help physicians provide optimal care to every patient. Evidence-based medicine is the future of orthopedic surgery. In a world where the quality of surgical outcomes will be increasingly measured, evidence-based data will heavily guide decision making in orthopedic trauma. Orthopedic Traumatology: An Evidence-Based Approach provides the reader with a focused and comprehensive review of the literature surrounding the management of the orthopedic trauma patient. The book centers around clinical scenarios with each chapter based on a specific case. Renowned orthopedic trauma surgeons from across the country serve as contributing authors, writing based on these scenarios and giving their expert opinions on management while using data as their guide. Each chapter describes and summarizes the data, but achieves this objective in a case-based format. Each case is brief, but includes relevant imaging. The case scenarios are heavily weighted toward treatment of more controversial injuries. As there is currently no book on the market that focuses solely on orthopedic trauma and evidence-based medicine, this book is sure to be a useful reference for residents and practicing physicians alike.
