Xi- and Xi+ production in Pb + Pb collisions at 40 A GeV at CERN SPS

First results on the production of Xi- and Anti-xi hyperons in Pb+Pb interactions at 40 A GeV are presented. The Anti-xi/Xi- ratio at midrapidity is studied as a function of collision centrality. The ratio shows no significant centrality dependence within statistical errors; it ranges from 0.07 to 0.15. The Anti-xi/Xi- ratio for central Pb+Pb collisions increases strongly with the collision energy

Measuring the impact of financial flows on macroeconomic variables: the case of Brazil after the 2008 crisis

The effects of changes in foreign portfolio investment flows on Brazilian GDP and investment during the financial crisis of 2008 are evaluated through impulse-response functions, parsimonious models, and out of sample forecasts. Impulse-response functions results show a positive relation between fixed income flows and GDP and investment, but this relation is not as strong between the real variables and equity flows, although these flows anticipate GDP and investment behavior. Expectations seem to have an important role in explaining GDP and investment, which also have an influence on flows. The reduced vulnerability of the Brazilian economy consequently lessened the effect of the crisis when compared with previous crisis episodes.foreign portfolio investment, growth, investment, crisis, Brazil

Hyperon production in Pb+Pb collisions at the CERN-SPS

New results on the production of Xi and Omega hyperons in Pb+Pb interactions at 40AGeV and Lambda at 30AGeV are presented. Transverse mass spectra as well as rapidity spectra of these hyperons are shown and compared to previously measured data at different beam energies. The energy dependence of hyperon production (4pi yields) is discussed. Additionally, the centrality dependence of Xi^{-} production at 40AGeV is presented.Comment: Quark Matter 2004 proceeding, to be published in Journal of Physics
