Interpretation of searches for supersymmetry with simplified models

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.

Search for gluino mediated bottom- and top-squark production in multijet final states in pp collisions at 8 TeV

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.

Regional integration in the Caribbean: The role of trade agreements and structural transformation

Despite having relatively open economies and a dedicated strategic focus on export expansion, Caribbean economies still account for a small proportion of global trade (goods and services). This paper therefore posits that the subregion adopt a new dais of regional integration, which favours deeper trade and economic integration with countries which are the region’s natural trading partners.

Economic survey of the Caribbean 2014: Reduced downside risks and better prospects for a recovery

The current survey provides an overview of the economic performance for 2013 of the Bahamas, Barbados, Belize, Guyana, Jamaica, Suriname, Trinidad and Tobago plus the eight member states of the Eastern Caribbean Currency Union (ECCU) and the outlook for 2014 and 2015. Data were collected from a review of reports from national governments and through interviews with government officials in each of the countries analyzed.

An assessment of the performance of CARICOM extraregional trade agreements: An initial scoping exercise

Despite its active embrace of trade liberalization and the maintainance of relatively open economies, CARICOM trade performance both within the region and extraregionally has been poor. The nexus between bilateral Free Trade Agreements (FTAs), Partial Scope Agreements (PSAs) and preferential trade arrangements, which was intended to assist in compensating for the small size of domestic and regional markets, while providing an additional tier of trade and economic integration, has thus far failed to deliver its intended results. This paper makes this conclusion in assessing the performance of these extraregional trade agreements and sheds light on issues not often discussed.

Trade and Development Nexus: reflections on the performance of trade in goods under the Cariforum-European Union Partnership agreement a Cariforum perspective

Given the asymmetry in the levels of development and capacity which exist between the EU and CARIFORUM States, the architects of the CARIFORUM-European Union (EU) Economic Partnership Agreement (EPA)1 anticipated the need for review and monitoring of the impacts of implementation. Article 5 and other provisions in the Agreement therefore specifically mandate that monitoring be undertaken to ensure that the Agreement benefits a wide cross-section of the population in member countries. The paper seeks to provide a preliminary assessment of the impact of the EPA on CARIFORUM countries. In so doing, it highlights some critical information and implementation gaps and challenges that have emerged during the implementation process. The analysis however, is restricted to goods trade. The services sector will be the subject of a separate report. The paper draws on a combination of quantitative and qualitative analyses. While the paper undertakes a CARIFORUM-wide analysis for the most part, five CARIFORUM member states including Barbados, Dominican Republic, Guyana, Saint Kitts and Nevis and Saint Lucia are examined more closely in some instances. These economies were selected by virtue of economic structure and development constraints, as a representative subset of CARIFORUM, which comprises the CARICOM membership as well as the Dominican Republic.

Trajetórias tecnológicas e sistemas agrários: qualificação territorial utilizando geoprocessamento em Paragominas e Santarém/PA

A Amazônia tem sido observada principalmente por meio do fenômeno do desmatamento, utilizando recursos tradicionais do sensoriamento remoto como a quantificação de área desflorestada e seu posterior incremento anual, que parece se constituir em uma metodologia eficaz. Ratificando este raciocínio, constatei num levantamento de 16.591 multas aplicadas pelo IBAMA/PA no período de 2000 até 2008, que mais de 85,0% das autuações estavam relacionadas apenas à componente flora;e na jurisdição da Gerência do IBAMA em Santarém, oeste do Pará, em 2008, quase 60% das multas se deu por conta de desflorestamento, identificados via sensoriamento remoto. Ressalta-se que as análises de imagens de satélites por si só não definem elementos da superfície terrestre, contribuindo pouco para o entendimento e posterior intervenção da realidade. Nesse contexto, foram investigados e vetorizados 479 estabelecimentos rurais nas regiões de Paragominas e Santarém, estado do Pará, que possuem históricos de uso e ocupação distintos, qualificando-os segundo suas trajetórias tecnológicas prevalentes, na perspectiva apresentada por Costa, concretizando um importante passo para correção das distorções no desenvolvimento econômico, agregando informação ao dado de sensoriamento remoto. Aplicaram-se recursos geotecnológicos de métricas de paisagem, construíram-se banco de dados celular integrado com estatísticas e algoritmos de otimização probabilística, associando dados de classificação não supervisionada isodata (validadas com kappa= 0,87, classificação considerada“excelente”) com os tipos de produção coletados em campo, gerando uma classificação final "integrada"(kappa= 0,78, classificação “muito boa”). Na região de Paragominas, foram qualificadas 3 tipos de trajetórias tecnológicas, a camponesa T8 (domínio de culturas temporárias), a camponesa T3 e patronal T4 (especializadas em pecuária de corte). Em Santarém, revelaram-se 2 trajetórias, a camponesa T2 (forte presença de culturas permanentes, temporárias e sistemas agro florestais) e a patronal T7 (mutação da T4, aumentando a participação das culturas temporárias). A metodologia aplicada logrou êxito, espacializando as propriedades rurais segundo seus tipos de trajetórias tecnológicas e gerando classes de uso mais representativas, como cultura temporária e pastagem, mas que na classificação via sensoriamento remoto isodata é englobada pela classe “agropecuária”, possibilitando uma visão mais realista das atividades de produção desenvolvidas na área investigada, concretizando a geração de informações espaciais integrando dados de diferentes fontes e o aumento do poder de leitura do pixel.
