Measurement of the Top Pair Production Cross section at ATLAS

We present the measurement of the production cross section for top quark pair ($t\bar{t}$) in pp collisions at $\sqrt{s}$ = 7 TeV using the data recorded with the ATLAS detector at the Large Hadron Collider (LHC). Events are selected in single lepton (electron or muon) and dilepton ($ee$, $\mu\mu$, $e\mu$) topologies with multi-jets, and large missing transverse energy (MET). The combined result from these measurements is $\sigma_{t\bar{t}}$ = $176 \pm 5 \mathrm{(stat.)} ^{+13}_{-10}\mathrm{(syst.)} \pm 7 \mathrm{(lumi.)} \mathrm{pb}$, which is in good agreement with the Standard Model prediction.Comment: 8 pages, 9 figures, Proceedings of the DPF-2011 Conference, Providence, RI, August 8-13, 201

Beyond the resource curse: minerals and global development

This repository item contains a single issue of Issues in Brief, a series of policy briefs that began publishing in 2008 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future.This policy brief discusses the concept of the “resource curse” and the often-assumed connection between a country’s significant mineral wealth and violence and corruption. The paper argues that developing countries with abundant mineral resources can have positive and equitable development programs by establishing long-range plans that address governance, economic and social policies, and ecological issues associated with mineral extraction, and establishing appropriate frameworks and infrastructure to carry out these plans
