Separate mass scaling of the widths of the rapidity distributions for mesons and baryons at energies available at the Facility for Antiproton and Ion research

Kalyan Dey, B. Bhattacharjee

摘要:

本文研究了在不同的FAIR(Facility for Antiproton and Ion Research)能量下,UrQMD-3.3p1产生的粒子的快度分布宽度对束流快度的影响。用UrQMD产生的事例得到的快度分布宽度随束流快度的变化结果与已有的实验数据(E802、E877、E896、E917、NA 49)进行了比较。对于UrQMD和实验数据,快度分布的宽度被发现承担标度行为与束快度的所有强子。这样的标度行为被发现遵循单独的质量排序所研究的介子和重子。

英文摘要:

Evolution of the width of the rapidity distribution on beam rapidity has been studied for a number of produced particles with UrQMD-3.3p1 generated events at various FAIR (Facility for Antiproton and Ion Research) energies. The results for the width of the rapidity distribution with beam rapidity, obtained with UrQMD generated events, are compared with the existing experimental data (E802, E877, E896, E917, NA49). For both UrQMD and experimental data, the width of the rapidity distribution is found to bear scaling behavior with beam rapidity for all the hadrons. Such scaling behavior is found to follow separate mass ordering for the studied mesons and and baryons.
