我们计算了πN弹性散射在一些已建立共振区的时间延迟。除了共振对应的正峰外,我们还确定了负时间延迟或时间超前的广泛区域。我们比较了用时间延迟法测定的共振参数和用常规方法测定的共振参数,并试图解释我们观察到的时间超前。
We evaluate the time delay in some of the established resonance regions of πN elastic scattering. In addition to the positive peaks corresponding to resonances, we identify broad regions of negative time delay or time advancement. We compare the resonance parameters determined with the time delay method with those from conventional methods and try to interpret our observation of time advancement.
