本文研究了D 7-膜在介子驱动背景下的介子谱。这导致了一个双规范理论与夸克禁闭由于规范凝聚。我们发现，在非超对称情况下，规范凝聚体对介子谱的影响是产生真实强子谱的必要条件。然而，在超对称的情况下，只有标量的光谱受到影响，但它们的变化与非超对称的情况相反。
Meson spectra given as fluctuations of a D7-brane are studied under the background driven by the dilaton. This leads to a dual gauge theory with quark confinement due to the gauge condensate. We find that the effect of the gauge condensate on the meson spectrum is essential in order to make a realistic hadron spectrum in the non-supersymmetric case. In the supersymmetric case, however, only the spectra of the scalars are affected, but they are changed in an opposite way compared to the non-supersymmetric case.
