Selecting specific initial configurations using spectator neutrons in U plus U collisions

Abstract

We present a method to select events with a specific initial configuration, namely, the body-tip, in heavy-ion collisions using deformed uranium nuclei. We propose to use asymmetry in spectator neutron numbers to filter out these body-tip events from the unbiased configurations in U+U collisions. We have used a variable S-eta to differentiate between the body-tip and unbiased configurations. We have calculated the second-order azimuthal anisotropy, namely, elliptic flow v(2), for this body-tip configuration in the framework of a transport model and found it to be consistently lower compared to that in unbiased configurations as we expected. The purity of selecting such events in a real experiment is also discussed.
