Description and performance of track and primary-vertex reconstruction with the CMS tracker

A description is provided of the software algorithms developed for the CMS tracker both for reconstructing charged-particle trajectories in proton-proton interactions and for using the resulting tracks to estimate the positions of the LHC luminous region and individual primary-interaction vertices. Despite the very hostile environment at the LHC, the performance obtained with these algorithms is found to be excellent. For t (t) over bar events under typical 2011 pileup conditions, the average track-reconstruction efficiency for promptly-produced charged particles with transverse momenta of p(T) > 0.9GeV is 94% for pseudorapidities of vertical bar eta vertical bar < 0.9 and 85% for 0.9 < vertical bar eta vertical bar < 2.5. The inefficiency is caused mainly by hadrons that undergo nuclear interactions in the tracker material. For isolated muons, the corresponding efficiencies are essentially 100%. For isolated muons of p(T) = 100GeV emitted at vertical bar eta vertical bar < 1.4, the resolutions are approximately 2.8% in p(T), and respectively, 10 m m and 30 mu m in the transverse and longitudinal impact parameters. The position resolution achieved for reconstructed primary vertices that correspond to interesting pp collisions is 10-12 mu m in each of the three spatial dimensions. The tracking and vertexing software is fast and flexible, and easily adaptable to other functions, such as fast tracking for the trigger, or dedicated tracking for electrons that takes into account bremsstrahlung.

Estudos sobre o subdesenvolvimento capitalista: as teorias de Paul A. Baran, Andre G. Frank e Ruy M. Marini

The underdevelopment is a high relevance subject in researches and studies for the general social sciences. In this monographic paper, the marxist analysis perspective of the phenomenon approached is considerate of great importance to make a deep overlook, historical and structural, about the origins and solutions possibilities for the issues caused by it over several countries. Has been done here a theoretical analysis of three studious marxist authors of the subject: Paul A. Baran, Andre G. Frank and Ruy M. Marini. How they thought underdevelopment? Which were their scientific contributions to this theme? The main goal of this paper is to do a comparative analysis of these authors, synthesize their considerations about the underdevelopment issues and organized a theoretical and conceptual framework for a better understanding of the matters in capitalist development/underdevelopment relationship. To accomplish that, we elected four variables that supports this comparative exercises, they are: the origins, the causes, the consequences and the way-out of the underdevelopment conditions. This monographic work was made through studies of some principals books and articles of the cited authors as well as the reading of others authors that commented their theories and concepts. The considerations about the underdevelopment vitality under a world capitalist logical, rescues the debate on the transformation of this entire society project for another, been this movement the only way possible to reverse the path of the world people’s history and the major part of humankind that still lives into the “necessity kingdom”

A personagem Bigger Thomas na obra de Richard Wright e a construção de identidade afro-americana

This paper analyzes the character Bigger Thomas Native Son’s American novel published in 1940 by African-American author Richard Wright. Through this character we try to study more the post-slavery racial issue in a country where racial segregation was legally sustained and how this issue was reflected in society and identity formation of their native sons African-American

European birth cohorts for environmental health research

Many pregnancy and birth cohort studies investigate the health effects of early-life environmental contaminant exposure. An overview of existing studies and their data is needed to improve collaboration, harmonization, and future project planning.
