在本文中,我们研究的定性特征胶球= 1 SYM的模型中的包裹膜IIA和IIB背景。标量模式,0++被发现是一个混合物的标量和内部部分的度量。我们对IIB背景进行了数值研究。发现的潜力表现出质量差距,并产生一个离散的光谱,没有任何截止。我们提出了一个正则化程序,需要使这些状态归一化。
In this paper we study qualitative features of glueballs in = 1 SYM for models of wrapped branes in IIA and IIB backgrounds. The scalar mode, 0++ is found to be a mixture of the dilaton and the internal part of the metric. We carry out the numerical study of the IIB background. The potential found exhibits a mass gap and produces a discrete spectrum without any cut-off. We propose a regularization procedure needed to make these states normalizable.
