We derive the flow-background formula for jet-correlation analysis with high p T trigger particles in any azimuth window relative to reaction plane, extending the mathematic framework of previous study in [1]. Strong interaction of hard-scattering partons with the high density medium 1 created in relativistic heavy-ion collisions results in modification to jet-correlation 2 with high transverse...

Large-eddy simulation (LES) is performed to investigate the passive scalar development in a plane jet. This is a follow-up of our previous simulation of the jet  owŽ eld. The LES results are compared to both experiments and direct numerical simulation (DNS). Two subgrid models are investigated: the dynamic Smagorinsky model and the dynamic mixed model. It is found that the evolution of mean sc...

We discuss the timescales for alignment of black hole and accretion disc spins in the context of binary systems. We show that for black holes that are formed with substantial angular momentum, the alignment timescales are likely to be at least a substantial fraction of the systems’ lifetimes. This result explains the observed misalignment of the disc and the jet in the microquasar GRO J 1655-40...

The shapes of jets with transverse energies, E T , up to 45 GeV produced in neutraland charged-current deep inelastic ep scattering (DIS) at Q > 100 GeV have been measured with the ZEUS detector at HERA. Jets are identified using a cone algorithm in the η − φ plane with a cone radius of one unit. The jets become narrower as E T increases. The jet shapes in neutraland charged-current DIS are fou...
