The results of searches for supersymmetry by the CMS experiment are interpreted in the framework of simplified models. The results are based on data corresponding to an integrated luminosity of 4.73 to 4.98 fb-1. The data were collected at the LHC in proton-proton collisions at a center-of-mass energy of 7 TeV. This paper describes the method of interpretation and provides upper limits on the product of the production cross section and branching fraction as a function of new particle masses for a number of simplified models. These limits and the corresponding experimental acceptance calculations can be used to constrain other theoretical models and to compare different supersymmetry-inspired analyses. © 2013 CERN.

A search for supersymmetry is presented based on events with large missing transverse energy, no isolated electron or muon, and at least three jets with one or more identified as a bottom-quark jet. A simultaneous examination is performed of the numbers of events in exclusive bins of the scalar sum of jet transverse momentum values, missing transverse energy, and bottom-quark jet multiplicity. The sample, corresponding to an integrated luminosity of 19.4fb-1, consists of proton-proton collision data recorded at a center-of-mass energy of 8TeV with the CMS detector at the LHC in 2012. The observed numbers of events are found to be consistent with the standard model expectation, which is evaluated with control samples in data. The results are interpreted in the context of two simplified supersymmetric scenarios in which gluino pair production is followed by the decay of each gluino to an undetected lightest supersymmetric particle and either a bottom or top quark-antiquark pair, characteristic of gluino mediated bottom- or top-squark production. Using the production cross section calculated to next-to-leading-order plus next-to-leading-logarithm accuracy, and in the limit of a massless lightest supersymmetric particle, we exclude gluinos with masses below 1170GeV and 1020GeV for the two scenarios, respectively. © 2013 CERN.

O presente estudo objetiva revisitar a equação igualdade-liberdade, especialmente as concepções de John Rawls, Ronald Dworkin e Hannah Arendt, para indicar qual dos dois valores possui valor normativo mais transcendente. Tendo em mente este desiderato, a referida equação foi analisada a partir das correntes doutrinárias do liberalismo do tempo presente confrontando-as com o pensamento político de Hannah Arendt, o que elevou o grau de complexidade da pesquisa considerando que ambos provêm de tradições filosóficas e políticas distintas. Ao longo do trabalho, procurou-se demonstrar, sobretudo amparado no pensamento político de Hannah Arendt, que a liberdade positiva, fundada no princípio do autogoverno e em combinação com a igualdade complexa, pode ser apontada como o valor mais transcendente dentro da famosa equação.

The paper has analyzed John R. Commons' contribution to the comprehension of Law and Economics relationship. In contrast to the orthodox economics, Commons has shown that the capitalist economic order emerges and functions regulated by laws and institutions. These approaches made possible to him to understand the nature of the modern capitalist wealth and the problems that time introduces in economic transactions.
