软壁模型中一种改进的膨胀子背景

An Improved Dilaton Background in Soft-Wall Model

Hongying Jin, Gang Liu

摘要:

本文采用了张平提出的体标量场的v.e.v.形式,并相应地将体标量场的背景由$e^{-κ^2z^2}$改为$e^{-κ^2z^2+αz}$。计算结果表明,只要选取适当的参数,在保持Regge行为不变的情况下,可以得到比现有的软壁模型和硬壁模型更好的结果。

英文摘要:

We adopted the form of v.e.v. of the bulk scalar field proposed by P.Zhang in this paper, and changed the dilaton background from $e^{-κ^2z^2}$ to $e^{-κ^2z^2+αz}$ accordingly. The calculation shows that, as if we choose proper parameters, we can get a better result than both the present soft-wall models and the hard-wall model while keeping Regge behavior unchanged.
