甘精球和Pomeron

Glueballs and the Pomeron

M. N. Sergeenko

摘要:

胶子球被认为是组成胶子的束缚态。分析了两个大质量胶子在漏斗势作用下的相对论波动方程。利用方程的两个精确渐近解,我们导出了一个插值质量公式,并计算了胶球质量,与晶格数据一致。我们得到了在整个$t$区域内的复杂非线性Pomeron轨道$α_P(t)$。轨迹的实部对应于软Pomeron,其参数从最近HERA数据的拟合中找到。

英文摘要:

Glueballs are considered to be bound states of constituent gluons. Relativistic wave equation for two massive gluons interacting by the funnel-type potential is analyzed. Using two exact asymptotic solutions of the equation, we derive an interpolating mass formula and calculate glueball masses in agreement with the lattice data. We obtain the complex non-linear Pomeron trajectory, $α_P(t)$, in the whole region of $t$. The real part of the trajectory corresponds to the soft Pomeron, parameters of which are found from the fit of recent HERA data.
