Anisotropic flow in the forward directions at sqrt(s_NN) = 200 GeV

The addition of the two Forward TPCs to the STAR detector allows one to measure anisotropic flow at forward pseudorapidities. This made possible the first measurement of directed flow at collision energies of sqrt(s_NN) = 200 GeV. PHOBOS' results on elliptic flow at forward rapidities were confirmed, and the sign of v2 was determined to be positive for the first time at RHIC energies. The higher harmonic, v4, is consistent with the recently suggested v2^2 scaling behavior.Comment: 4 pages, 5 figures; write-up of a poster (see http://cern.ch/Oldenburg/Talks/QM2004_Flow_Poster.pdf) presented at Quark Matter 2004, Oakland; reference 10 correcte

The Vlasov-Poisson system with radiation damping

We set up and analyze a model of radiation damping within the framework of continuum mechanics, inspired by a model of post-Newtonian hydrodynamics due to Blanchet, Damour and Schaefer. In order to simplify the problem as much as possible we replace the gravitational field by the electromagnetic field and the fluid by kinetic theory. We prove that the resulting system has a well-posed Cauchy problem globally in time for general initial data and in all solutions the fields decay to zero at late times. In particular, this means that the model is free from the runaway solutions which frequently occur in descriptions of radiation reaction
