Azimuthally-sensitive two-pion interferometry in U+U collisions at STAR

Collisions between uranium nuclei have been produced at the Relativistic Heavy Ion Collider and measured in the STAR detector. Due to the prolate deformation of the nuclei, fully overlapping U+U collisions offer the opportunity to produce highly anisotropic participant zones, similar in shape to mid-central Au+Au collisions, but with twice the size. The larger fireball should be characterized by a long lifetime over which it collectively evolves from its non-trivial initial shape to its final one. The final-state anisotropy of zero-spectator collisions in momentum space (v$_{n}$) is under study. We will present an analysis of the coordinate-space anisotropy, measured via azimuthally-sensitive two-pion interferometry (``HBT'') of full-overlap collisions, performed differentially via the reduced flow parameter q$_{2}$ in U+U collisions at $\sqrt{s_{NN}}$ 193 GeV.
