Difficulties in probing density dependent symmetry potential with the HBT interferometry
Difficulties in probing density dependent symmetry potential with the HBT interferometry
Based on the updated UrQMD transport model, the effect of the symmetry potential energy on the two-nucleon HBT correlation is investigated with the help of the coalescence program for constructing clusters, and the CRAB analyzing program of the two-particle HBT correlation. An obvious nonlinear dependence of the neutron-proton (or neutron-neutron) …
