Observation of a new boson with mass near 125 GeV in pp collisions at $ \sqrt{s}=7 $ and 8 TeV

Abstract: A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample corresponds to integrated luminosities up to 5.1 inverse femtobarns at sqrt(s) = 7 TeV, and up to 5.3 inverse femtobarns at sqrt(s) = 8 TeV. The results for five Higgs boson decay modes gamma gamma, ZZ, WW, tau tau, and bb, which show a combined local significance of 5 standard deviations near 125 GeV, are reviewed. A fit to the invariant mass of the two high resolution channels, gamma gamma and ZZ to 4 ell, gives a mass estimate of 125.3 +/- 0.4 (stat) +/- 0.5 (syst) GeV. The measurements are interpreted in the context of the standard model Lagrangian for the scalar Higgs field interacting with fermions and vector bosons. The measured values of the corresponding couplings are compared to the standard model predictions. The hypothesis of custodial symmetry is tested through the measurement of the ratio of the couplings to the W and Z bosons. All the results are consistent, within their uncertainties, with the expectations for a standard model Higgs boson.

Phase III Randomized Trial Comparing Doxorubicin and Cyclophosphamide Followed by Docetaxel (AC→T) with Doxorubicin and Cyclophosphamide Followed by Docetaxel and Trastuzumab (AC→TH) with Docetaxel, Carboplatin and Trastuzumab (TCH) in Her2neu Positive Early Breast Cancer Patients: BCIRG 006 Study.

Abstract: Background: Evaluation of the long-term benefit of biologically-based regimens of trastuzumab in the early breast cancer population, and optimization of trastuzumab integration to maximize efficacy and minimize cardiac toxicity. Material and Methods: We randomized HER2-positive (FISH+) breast cancer patients with axillary lymph node positive or high risk negative, to either standard AC (60/600 mg/m 2 q3wk x4) followed by T (100 mg/m 2 q3wk x 4) or two trastuzumab-containing regimens; AC followed by T with trastuzumab x 1 year or TCarbo (75 mg/m 2 /AUC6 q3wk x 6) with trastuzumab x 1 year. Patients were prospectively stratified by number of positive nodes (0, 1-3 vs 4+) and hormone receptor status. Patients with ER and/or PR positive (HR+) tumors received hormone-directed therapy for 5 yrs after chemotherapy. The primary endpoint was disease-free survival (DFS) with 80% power (0.05 significance level) to detect an absolute difference of 7%. Secondary endpoints include overall survival (OS) and safety, including cardiac toxicity (symptomatic events and asymptomatic LVEF decline). The first two protocol-specified analyses for this study were performed at 300 and 450 disease-related events. We now report the results of the third protocol-specified analysis conducted after 650 events, expected by end of June 2009. Results: A total of 3222 patients (1072 in AC-T, 1076 in AC-TH and 1074 in TCH) were recruited between April 2001 and March 2004. Baseline characteristics of the study population will be included. Cox analysis of DFS and OS (unadjusted and adjusted for nodal status) and cardiac toxicity data will be presented for the three treatment arms. Discussion: The results of this trial help define the role of trastuzumab in the breast cancer HER2-positive adjuvant setting, as well as the risks/benefits of adjuvant trastuzumab within the context of overall safety including cardiac toxicity. This latter objective is of particular importance given that many of these women may be cured of their disease in the adjuvant setting.

Salesperson Adaptive Selling Behavior and Customer Orientation: A Meta-Analysis

Abstract: The authors combine findings from 155 samples of more than 31,000 salespeople to test alternative models of antecedents and consequences of adaptive selling behavior (ASB) and customer orientation (CO). A random-effects meta-analysis yields average values for 28 different correlations ranging from −.16 to .35, 19 of which are significant. Controlling for salesperson gender and selling experience, structural equation modeling indicates that ASB increases self-rated, manager-rated, and objective measures of performance, whereas CO increases only self-rated performance. Both ASB and CO increase job satisfaction. Tests of reciprocal relationships indicate that ASB increases CO and job satisfaction increases performance rather than vice versa. Selling experience increases performance but not job satisfaction, and saleswomen rate their performance and satisfaction slightly higher than salesmen do. The magnitudes of the relationships indicate that ASB and selling experience have greater effects than CO ...
