From ballistic to Brownian vortex motion in complex oscillatory media
Jörn Davidsen, Ronaldo Erichsen, Raymond Kapral +1
We show that the breaking of the rotation symmetry of spiral waves in two-dimensional complex (period-doubled or chaotic) oscillatory media by synchronization defect lines (SDL) is…
Heavy quark photoproduction in proton-proton collisions
V. P. Goncalves, M. V. T. Machado
We calculate the photoproduction of heavy quarks in proton-proton collisions at RHIC, Tevatron and LHC energies. The integrated cross section and the rapidity distributions for ope…
A phenomenological analysis of the longitudinal structure function at small and low
V. P. Goncalves, M. V. T. Machado
The longitudinal structure function in deep inelastic scattering is one of the observables from which the gluon distribution can be unfolded. Consequently, this observable can be u…
Discovery of three optical open clusters in the Galaxy
E. Bica, C. Bonatto, C. M. Dutra
We report the discovery of three optical open clusters in the Milky Way. Two clusters are in Scutum (Cluster1 at l=18.44 degrees and b=-0.42 degrees, and Cluster2 at l=19.60 degree…
Nuclear exclusive vector meson photoproduction
V. P. Goncalves, M. V. T. Machado
We calculate the nuclear cross section for vector meson exclusive photoproduction within the QCD color dipole picture and in the Regge approach. For the former approach, we have co…
