Signatures of an α plus core structure in 44 Ti+44 Ti collisions at √sNN=5.02=5.02 TeV by a multiphase transport model

It is important to understand whether alpha-clustering structures can leave traces in ultra-relativistic heavy ion collisions. Using the modified AMPT model, we simulate three alpha+ core configurations of44Ti in Ti-44+Ti-44 collisions at root sNN=5.02 TeV as well as other systems with Woods-Saxon structures. One of these configurations has no addi-tional constraint, but the other two have the Mott density edge r(Mott )set as either a lower or upper bound on the cluster position r alpha to check the influence of alpha dissolution. This is the first time that the initial stage of the geometric properties in heavy-ion collisions has been configured using the traditional treatment of the nuclear structure. We compare the radial nucleon density, multiplicity distribution, transverse momentum spectra, eccentricity, triangularity, elliptic flow and triangular flow of these six systems.alpha+core structure scan alter all these observations especially in the most-central collisions, among which elliptic flow is the most hopeful a sa probe of such structures.
