CR质子的超高能相互作用

Ultra High-Energy Interaction of CR protons

Tadeusz Wibig

摘要:

最近的俄歇结果表明,虽然与“附近”AGN和HiRes发现的GZK截止的到达方向的重合表明质子,测量的纵向传播特性表明重核,如果传统的相互作用模型是正确的。必须有所改变!我们自己的观点是,活动星系核暗示的质子识别可能是不正确的,而星系外粒子实际上主要是“粒子”,在这种情况下,相互作用问题就消失了。然而,在这里我们假设粒子是质子,并检查可能的结果。讨论的参数包括相互作用的平均自由程,非弹性和“异国情调”的可能性。

英文摘要:

The recent Auger results suggest that although coincidences of arrival directions with 'nearby' AGN and HiRes discovery of the GZK cut-off indicate protons, the measured longitudinal propagation characteristics indicate heavy nuclei, if the conventional interaction model is correct. Something has to change! Our own view is that it is possible that the AGN -implied proton identification is not correct and that the extra galactic particles are, in fact, mainly 'heavies', in which case the interaction problem goes away. However, here we assume that the particles ARE protons and examine the possible consequences. Parameters discussed include the interaction mean-free-path, inelasticities and 'exotic' possibilities.
