Femtoscopy analysis of d-Au interactions at $\sqrt{s}=200$GeV

Understand

The femtoscopy correlation radii for d-Au collisions at $200$GeV 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 $R_{out-long}$ 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.
