| 英文摘要 | Magnetic-field effects on free nucleons are studied in peripheral collisions of Au-197+Au-197 at energies ranging from 600 to 1500 MeV/nucleon by utilizing an isospin-dependent quantum molecular-dynamics (IQMD) model. With the help of angular distributions and two-particle angular correlators, the magnetic-field effect at an impact parameter of 11 fm is found to be more obvious than at an impact parameter of 8 fm. Moreover, the results suggest that, with an increase in the number of peripheral collisions, protons are more easily condensed with the magnetic field. Magnetic-field effects are further investigated by the ratio of free neutrons to free protons as functions of a two-particle correlator C-2, four-particle correlator C-4, and six-particle correlator C-6 of angle phi, rapidity Y, and transverse momentum p(T). The results show that weak magnetic-field effects could be revealed more clearly by these multiple-particle correlators, with the larger number of particle correlators demonstrating a clear signal. The results highlight a new method to search for weak signals using multiparticle correlators. |
