Fragment productions in DJBUU and SQMD: comparative study

Abstract

We study ${}^{208}$Pb+${}^{40,48}$Ca reactions at $E_{\mathrm{beam}}$ = 50, 100 AMeV with DJBUU and SQMD transport codes. We compare the large primary fragments from the two codes at the end of the simulation time. We observe that overall the two models produce similar fragments. However, we see a noticeable difference between DJBUU and SQMD at $E_{\mathrm{beam}}=100$ AMeV with the impact parameter $b$ = 0 fm and discuss this difference in terms of the difference in the equation of state adopted in the two models and the difference in stability inherent to the BUU-type and QMD-type models.
