Search for top squark production in fully hadronic final states in proton-proton collisions at root s=13 TeV

A search for production of the supersymmetric partners of the top quark, top squarks, is presented. The search is based on proton-proton collision events containing multiple jets, no leptons, and large transverse momentum imbalance. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 137 fb(-1). The targeted signal production scenarios are direct and gluino-mediated top squark production, including scenarios in which the top squark and neutralino masses are nearly degenerate. The search utilizes novel algorithms based on deep neural networks that identify hadronically decaying top quarks and W bosons, which are expected in many of the targeted signal models. No statistically significant excess of events is observed relative to the expectation from the standard model, and limits on the top squark production cross section are obtained in the context of simplified supersymmetric models for various production and decay modes. Exclusion limits as high as 1310 GeVare established at the 95% confidence level on the mass of the top squark for direct top squark production models, and as high as 2260 GeV on the mass of the gluino for gluino-mediated top squark production models. These results represent a significant improvement over the results of previous searches for supersymmetry by CMS in the same final state.Peer reviewe

Exame andrológico em touros: qualidade dos indicadores da aptidão reprodutiva em distintos grupos raciais Andrologycal examination in bulls: quality of breedng soundness criteria in different genetic groups

Os padrões recomendados para os componentes do exame andrológico são únicos para todas as raças e sistemas de produção, resultando em perdas económicas pela eliminação de reprodutores em alguns conjuntos raciais. O presente estudo apresenta uma análise retrospectiva sobre dois conjuntos de dados de campo, comparando grupos contemporâneos de touros de raças puras taurinas e derivadas de cruzamento com zebuínos. Os resultados indicam que o uso de padrões mais flexíveis resultam em um comportamento semelhante dos distintos grupos raciais, quanto à condição reprodutiva, em contraste com os critérios atuais que classificam de maneira diferente animais de distintos genótipos taurinos puros e seu cruzamento com zebuínos. É enfatizada a importância de estudos sobre os critérios recomendados para a classificação reprodutiva de touros, no sentido de reduzir perdas impostas aos sistemas de produção em decorrência de peculiaridades inerentes a grupos genéticos diferenciados.<br>There is a single set of standard for breeding soundness evaluation in bulls for ali breeds and production systems, resulting in economical losses due to high frequencies of culling in bulls of some genotypes. This study presents an analysis on two sets of field data, comparing contemporary groups of bulls from taurine pure-breds and zebu crossbreeds. The results were indicative that more flexible standards could be useful, avoiding injustified culling of bulls. This fact may be justified by the absence of interaction between breed and reproductive condition. It will be importam to continue the studies on procedures and standards for breeding soundness evaluation in bulls, to reduce losses in the production systems due to peculiarities inherent to the genetic groups

Search for top squark production in fully-hadronic final states in proton-proton collisions at s=\sqrt{s} = 13 TeV

A search for production of the supersymmetric partners of the top quark, top squarks, is presented. The search is based on proton-proton collision events containing multiple jets, no leptons, and large transverse momentum imbalance. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 137 fb$^{-1}$. The targeted signal production scenarios are direct and gluino-mediated top squark production, including scenarios in which the top squark and neutralino masses are nearly degenerate. The search utilizes novel algorithms based on deep neural networks that identify hadronically decaying top quarks and W bosons, which are expected in many of the targeted signal models. No statistically significant excess of events is observed relative to the expectation from the standard model, and limits on the top squark production cross section are obtained in the context of simplified supersymmetric models for various production and decay modes. Exclusion limits as high as 1310 GeV are established at the 95% confidence level on the mass of the top squark for direct top squark production models, and as high as 2260 GeV on the mass of the gluino for gluino-mediated top squark production models.
