Observing the azimuthally varying seismic attenuation in data that show azimuthal velocity anisotropy could contribute not only to the interpretation of the subsurface symmetry systems, but also to the characterization of its physical parameters. In this paper, we estimate azimuthal variations of the P-wave effective quality factor (Q) from field surface seismic data. We also provide an interpr...

We demonstrate that the existence of a finite formation time of strongly interacting plasma in nuclear collisions at RHIC is an inavitable conclusion from recent experimental data. The most striking feature of the experimental data an absense of absorption of high transverse momentum pions in the rection plane direction for mid-peripheral collisions points to the presence of a surface zone with...
