Description
Through $^{12}$C + $^{197}$Au collisions at $\sqrt{s_{NN}} =$ 200 GeV using a multiphase transport (AMPT) model, the azimuthal angle dependences of the Hanbury Brown-Twiss (HBT) radii relative to the second- and third-order participant plane from $\pi$-$\pi$ correlations are discussed.
Three initial geometric configurations of $^{12}$C, namely three-$\alpha$-cluster triangle, three-$\alpha$-cluster chain and Woods-Saxon distribution of nucleons, are taken into account, and their effects on the correlations are investigated.
We find that the ratio of the third-order to the second-order HBT radii is quite sensitive to different configurations of $^{12}$C.
In addition, this work presents the hadronic rescattering time evolution of the azimuthally dependent HBT radii.
From the present study, one can learn that the HBT correlation from identical particles at freeze-out is able to provide the information of different initial configurations as collective flow proposed before.
