主 题：electromagnetic form factors baryon-antibaryon pair production electron-positron annihilation
摘 要：Based on the recent precise measurements by the BESIII collaboration for electron–positron annihilation into a neutron and antineutron pair,the effective form factors of the neutron were determined in the time-like region,and it was found that the effective form factors of the neutron are smaller than those of the *** effective form factors of the neutron show a periodic behaviour,similar to those of the ***,a comparative analysis forΛ,∑^(0)and■hyperons is *** of the available data on the effective form factors ofΛ,∑^(0)and■with zero charge show an interesting phenomenon in the oscillating behavior of their effective form ***,this will need to be confirmed by future precise *** theoretical and experimental investigations of this phenomenon can shed light on the reaction mechanisms of the electron–positron annihilation processes.
