高能软相互作用的N=4 SYM模型

N=4 SYM model for soft interactions at high energy

E Levin, I. Potashnikova

摘要:

本文比较了N=4 SYM模型中高能软相互作用的预测与实验结果。结果表明,该模型仅用三个自由参数就能描述总截面、弹性截面和非弹性截面以及弹性坡度。然而,该模型未能获得衍射产生的截面,这是接近的实验数据,给他们的小值。我们认为,寻找大质量衍射的起源需要$1/λ$量级的N=4 SYM理论。

英文摘要:

In this paper we compare the prediction for high energy soft interactions in the model of N=4 SYM, with the experimental data. It is shown that this model is able to describe the total, elastic and inelastic cross sections and the elastic slope with only three free parameters. However, the model failed to obtain the cross sections for diffractive production, which was close to the experimental data, giving small values for them. We believe that the theory of N=4 SYM, of the order of $1/λ$ is needed to find the origin of large mass diffraction.
