接近领先的雷吉极点

An approach to the leading Regge pole

S. D. Campos

摘要:

忽略自旋效应,这里介绍了一个微妙的近似散射角,它允许获得一个对数领先的雷吉极点,符合Froissart-Martin界限。一个简单的参数化也介绍了质子-质子总截面。拟合程序只适用于最高能量的实验数据。得到了线性近似的截距,表明存在软坡密子。在碰撞参量空间中的Tsallis熵使用Regge极点形式主义计算。这个熵依赖于一个自由参数,它的值意味着熵的中心或非中心最大值的存在。空心效应进行了讨论,在此参数。

英文摘要:

Neglecting spin effects, one introduces here a subtle approximation for the scattering angle, which allows the obtaining of a logarithmic leading Regge pole, consistent with the Froissart-Martin bound. A simple parameterization is also introduced for the proton-proton total cross section. Fitting procedures are implemented only for the highest energy experimental data available. The intercept for a linear approach is obtained, indicating the presence of a soft pomeron. The Tsallis entropy in the impact parameter space is calculated using the Regge pole formalism. This entropy depends on a free parameter, whose value implies the existence of a central or non-central maximum value for the entropy. The hollowness effect is discussed in terms of this parameter.
