Higgs Searches

We present the status and prospects of Higgs searches at the Tevatron and the LHC. Results from the Tevatron are using up to 5/fb of data collected with the CDF and D0 detectors. The major contributing processes include associated production with vector bosons and gluon fusion. Improvements across the full mass range resulting from the larger data sets, improved analyses techniques and increased signal acceptance are discussed. Recent results exclude the SM Higgs boson in a mass range of 160 < mH < 170 GeV. Searches for the neutral MSSM Higgs boson in the region 90 < mA < 200 GeV exclude tanB values down to 30 for several benchmark scenarios.Comment: 6 pages, 13 figures, to be submitted in "XXIX Physics in Collision, Proceedings of the International Symposium in Kobe, Japan, August 30 - September 2, 2009

Heavy quark production and non-linear gluon evolution at the LHC

We investigate the importance of unitarity corrections to parton evolution in heavy flavor production at the LHC. The gluon distribution is determined with a fit to HERA data applying a unified BFKL-DGLAP approach, in which the non-linear evolution is described by the Balitsky-Kovchegov equation. First we estimate b anti-b production at CDF and D0. Then, cross sections for heavy quark production at various LHC experiments are estimated, tracing the impact of the unitarity corrections.Comment: Presented at the XIV International Workshop on Deep Inelastic Scattering, April 20-24, Tsukuba, Japan, 5 pages, 2 figure

Hard Diffractive Results and Prospects at the Tevatron

We review hard diffractive results and prospects at the Tevatron with an emphasis on factorization breaking in diffractive processes. Upper limits on the exclusive di-jet and chi_c^0 production cross sections at CDF and the status of the D0 Forward Proton Detectors are discussed.Comment: 6 pages, 6 figures, presented at the XXXV International Symposium on Multiparticle Dynamics 2005, August 9-15, 2005, Kromeriz, Czech Republi

Wave-structure interaction for long wave models in the presence of a freely moving body on the bottom

In this paper we address a particular fluid-solid interaction problem in which the solid object is lying at the bottom of a layer of fluid and moves under the forces created by waves travelling on the surface of this layer. More precisely, we consider the water waves problem in a fluid of fixed depth with a flat bottom topography and with an object lying on the bottom, allowed to move horizontally under the pressure forces created by the waves. After establishing the physical setting of the problem, namely the dynamics of the fluid and the mechanics of the solid motion, as well as analyzing the nature of the coupling, we examine in detail two particular shallow water regimes: the case of the (nonlinear) Saint-Venant system, and the (weakly nonlinear) Boussinesq system. We prove an existence and uniqueness theorem for the coupled system in both cases. Using the particular structure of the coupling terms we are able to go beyond the standard scale for the existence time of solutions to the Boussinesq system with a moving bottom.Comment: 37 pages, 1 imag

The effect of health conscious trends on food consumption

Food choice and food consumer behaviour is multifactoral behaviour, influenced by a large number of factors. Consumer way of life and health are relevant factors to understanding consumption preferences. In the last few decades the number of so-called civilization diseases has dramatically increased. Research has proved that the main cause for these diseases is the change in way of life; including rising stress in a fastpaced world and a lack of attention to physical activity and good nutrition. Nutrition and bad dietary habits have the greatest influence on weight gain and obesity, which are serious public health problems because the increased risk of premature death and civilization diseases like heart diseases, high blood pressure and diabetes. The state of health in the European countries was examined, with special focus on Hungary, regarding public health indicators and nutrition habits. Data was collected from FAOSTAT and EUROSTAT database. The life expectancy in Hungary is one of the worst of the European countries and the rate of obesity exceeds the average in Europe. From research and observations, one difference is that people in Hungary eat less of some foods deemed healthful by nutritional scientists, such as vegetables, fruits and milk. Improving the state of health is a notable task in Hungary, and one important part of the solution is changing bad dietary habits.health, nutrition, marketing, Food Consumption/Nutrition/Food Safety,

EMPLOYMENT CRISIS IN AGRICULTURE AND THE SPATIAL INEQUALITIES IN HUNGARY

Main objective of the paper is to discover Hungary’s rural areas suffering from agricultural employment crisis and to compare them to the spatial inequalities, examining the development possibilities and the adaptability to new economic and social processes. The actuality of this objective has been given by the recent processes in the global, European and Hungarian economy, the growing importance of local development and endogenous resources, the decreasing role of agriculture in total employment, and the general problems of rural areas. Based on multivariable statistical methods (factorial-, discriminant- and cluster analyses) and the data of 15 years before the EU accession, the selected micro-regions could be reliable separated by the economical state and social situation, the education, and the dependence on the agriculture. It can be stated that the concentrated, long-term agricultural unemployment is in close correlation to territorial inequalities, due to the unfavorable demographic and educational structure of the labor-force leaving the agriculture, the inadequate local resources, the underdevelopment and the lack of other possibilities of employment common to the identified micro-regions.agriculture, inequalities, rural development, unemployment, Community/Rural/Urban Development, Labor and Human Capital,

Search for the Higgs boson in the gamma gamma final state at the Tevatron

We present searches for Higgs bosons decaying to the di-photon final state using up to 5.4/fb of data at a center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. Whilst the branching ratio to the di-photon final state is small in the Standard Model, this channel contributes appreciably to the overall Higgs sensitivity at the Tevatron. In parallel, the limit is re-interpreted in fermiophobic models where the di-photon branching ratio is considerably larger. This decay channel will be of major importance in the light mass Standard Model Higgs search at the LHC.Comment: 5 pages, 3 figures, to appear in the proceedings of "35th International Conference of High Energy Physics - ICHEP2010

Towards Building a Knowledge Base of Monetary Transactions from a News Collection

We address the problem of extracting structured representations of economic events from a large corpus of news articles, using a combination of natural language processing and machine learning techniques. The developed techniques allow for semi-automatic population of a financial knowledge base, which, in turn, may be used to support a range of data mining and exploration tasks. The key challenge we face in this domain is that the same event is often reported multiple times, with varying correctness of details. We address this challenge by first collecting all information pertinent to a given event from the entire corpus, then considering all possible representations of the event, and finally, using a supervised learning method, to rank these representations by the associated confidence scores. A main innovative element of our approach is that it jointly extracts and stores all attributes of the event as a single representation (quintuple). Using a purpose-built test set we demonstrate that our supervised learning approach can achieve 25% improvement in F1-score over baseline methods that consider the earliest, the latest or the most frequent reporting of the event.Comment: Proceedings of the 17th ACM/IEEE-CS Joint Conference on Digital Libraries (JCDL '17), 201
