Testing the resolving power of two-dimensional K+K+ interferometry
(1998-11-01)
We show results from an analysis performed to test the resolving power of a two-dimensional χ2 method proposed previously when applied to the case of kaon interferometry, where no significant contribution from long-lived ...
Jet momentum dependence of jet quenching in PbPb collisions at root s(NN)=2.76 TeV
(Elsevier B.V., 2012-06-06)
Dijet production in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 150 mu b(-1) is analyzed. ...
Measurements of differential cross sections of Z/gamma* plus jets plus X events in p(p)over-bar collisions at root s=1.96 TeV
(Elsevier B.V., 2009-07-06)
We present cross section measurements for Z/gamma* + jets + X production, differential in the transverse momenta of the three leading jets. The data sample was collected with the do detector at the Fermilab Tevatron p (p) ...
The role of Mab as a source for the mu ring of Uranus (Research Note)
(Edp Sciences S A, 2012-07-01)
Context. We previously analysed how the solar radiation force combined with the planetary oblateness changes the orbital evolution of a sample of dust particles located at the secondary ring system of Uranus. Both effects ...
Isotopic evidence for the late Brasiliano (500-550 Ma) ore-forming mineralization of the Araes gold deposit, Brazil
(Bellwether Publ Ltd, 2008-02-01)
The Araes gold deposit, located in eastern Mato Grosso State, central Brazil, is hosted in Neoproterozoic volcanosedimentary rocks of the Paraguay belt, which formed during collision of the Amazonian craton and the Rio Apa ...
Measurement of differential Z/gamma* plus jet plus X cross sections in p(p)over-bar collisions at root S=1.96 TeV
(Elsevier B.V., 2008-11-27)
We present new measurements of differential cross sections for Z/gamma* (-> mu mu) + jet + X production in a 1 fb(-1) data sample collected with the do detector in p (p) over bar collisions at root s = 1.96 TeV. Results ...
Boundary crisis and transient in a dissipative relativistic standard map
(Elsevier B.V., 2011-09-05)
Some dynamical properties for a problem concerning the acceleration of particles in a wave packet are studied. The model is described in terms of a two-dimensional nonlinear map obtained from a Hamiltonian which describes ...
Fermi acceleration and its suppression in a time-dependent Lorentz gas
(Elsevier B.V., 2011-02-15)
Some dynamical properties for a Lorentz gas were studied considering both static and time-dependent boundaries. For the static case, it was confirmed that the system has a chaotic component characterized with a positive ...
Wave-packet dynamical analysis of ultracold scattering in cylindrical waveguides
(Amer Physical Soc, 2007-11-01)
A wave-packet propagation method is developed and applied to investigate the quantum dynamics of scattering processes of identical and distinguishable atoms in harmonic waveguides. the quantum dynamics of the confinement-induced ...
U-Pb geochronology of the southern Brasília belt (SE-Brazil): Sedimentary provenance, Neoproterozoic orogeny and assembly of West Gondwana
(2004-04-20)
The Brasília belt borders the western margin of the São Francisco Craton and records the history of ocean opening and closing related to the formation of West Gondwana. This study reports new U-Pb data from the southern ...
