形变AdS/QCD的夸克-反夸克势

Quark-antiquark potential from a deformed AdS/QCD

Rodrigo C. L. Bruni, Eduardo Folco Capossoli, Henrique Boschi-Filho

摘要:

在这项工作中,我们计算的静态限制的夸克-反夸克对的能量从南武-后藤作用使用全息方法与变形的AdS空间,与翘曲因子$\exp\{(κz)^n/n\}$。从这个能量中,我们导出了夸克-反夸克相互作用的康奈尔势。我们还找到了一个范围内的值,我们的参数,完全符合康奈尔潜在的参数。特别地,将康奈尔势的零能量设为0.33费米,我们发现$κ=0.56$ GeV和$n=1.3$。

英文摘要:

In this work we calculate the static limit of the energy for a quark-antiquark pair from the Nambu-Goto action using a holographic approach with a deformed AdS space, with warp factor $\exp\{(κz)^n/n\}$. From this energy we derive the Cornell potential for the quark-antiquark interaction. We also find a range of values for our parameters which fits exactly the Cornell potential parameters. In particular, setting the zero energy of the Cornell potential at 0.33 fermi, we find that $κ=0.56$ GeV and $n=1.3$.
