摘要:

我们研究了当三重坡密子顶点被假定为具有矢量形式时,即高质量衍射解离的振幅随$V \propto \vec q_t \cdot \vec e$和$q_t \to 0$的变化而消失的情况。我们发现,在三重Reggeon区域的可用数据可以很好地描述在这样一个“弱”耦合的情况下,吸收效应被考虑在内。我们比较这种弱(矢量)耦合的情况下,强和弱(标量)耦合的情况。相应的预测提出了14 TeV的LHC能量。

英文摘要:

We study the case when the triple-Pomeron vertex is assumed to have a vectorial form, that is, the amplitude of high-mass diffractive dissociation vanishes as $V \propto \vec q_t \cdot \vec e$ as $q_t \to 0$. We find that the available data in the triple-Reggeon region may be well described in such a `weak' coupling scenario, providing that absorptive effects are taken into account. We compare this weak (vector) coupling scenario with the strong and weak (scalar) coupling scenarios. Corresponding predictions are presented for an LHC energy of 14 TeV.
