Femtoscopy analysis of d-Au interactions at s=200GeV
Abstract
The femtoscopy correlation radii for d-Au collisions at 200GeV are calculated in the hydrodynamic model and compared to PHENIX collaboration data. For asymmetric systems, such as d-Au or p-Pb collisions, the correlation radius Rout-long is estimated and predicted to be non-zero. It appears due to different lifetimes of the parts of the fireball at positive and negative rapidities. Azimuthally sensitive Hanbury Brown-Twiss analysis with respect to the second order event plane shows a significant angular dependence of the radii. It reflects the strong azimuthal asymmetry of the d-Au source geometry and flow for central interactions.
