Deformed flux tubes produce azimuthal anisotropy in heavy ion collisions

The method for analysing jet azimuthal anisotropy in ultrarelativistic heavy ion collisions

The azimuthal anisotropy of jet spectra due to energy loss of jet partons in azimuthally non-symmetric volume of dense quark-gluon matter is considered for semi-central nuclear interactions at collider energies. We develop the techniques for event-by-event analysing jet azimuthal anisotropy using particle and energy elliptic flow, and suggest the method for calculating coefficient of jet azimut...

Azimuthal dependence of collective expansion for symmetric heavy-ion collisions.

Detailed studies of the azimuthal dependence of the mean fragment and flow energies in the Au+Au and Xe+CsI systems are reported as a function of incident energy and centrality. Comparisons between data and model calculations show that the flow energy values along different azimuthal directions could be viewed as snapshots of the fireball expansion with different exposure times. For the same nu...

Scaling of anisotropy flows in intermediate energy heavy ion collisions

Anisotropic flows (v 1 , v 2 and v 4) of light nuclear clusters are studied by a nucleonic transport model in intermediate energy heavy ion collisions. The number-of-nucleon scal-ings of the directed flow (v 1) and elliptic flow (v 2) are demonstrated for light nuclear clusters. Moreover, the ratios of v 4 /v 2 2 of nuclear clusters show a constant value of 1/2 regardless of the transverse mome...

Azimuthal Anisotropy of Identified Hadrons in 200 GeVAu + Au Collisions

The azimuthal anisotropy parameter v 2 has been measured with high statistics for identified hadrons in √ s N N = 200 GeV Au+Au collisions with the STAR experiment. At high transverse momentum (p T) a strong v 2 for π + + π − and p + p is observed. In the intermediate p T region, number-of-constituent-quark scaling was tested to high precision. A detailed comparison of v 2 for the multi-strange...
