关于标量胶球质量的AdS/QCD估计

On the AdS/QCD estimates of the scalar glueball mass

Herintsitohaina M. Ratsimbarison

摘要:

我们审查标准的全息推导的标量胶球光谱,并强调计算的假设,强烈依赖于原来的AdS/CFT对应,和那些更任意。在软壁模型中,我们明确地证明了两点标量胶子相关器的Kallen-Lehmann表示中谱质量约束的对偶是对应于该相关器的体场运动方程的本征值约束.

英文摘要:

We review standard holographic derivations of the scalar glueball spectra and emphasize computational assumptions which rely strongly on the original AdS/CFT correspondence, and those which are more arbitrary. In the soft-wall model, we show explicitly that the dual of the spectral mass constraint in the Kallen-Lehmann representation of the 2-point scalar gluonic correlator is an eigenvalue constraint on the motion equation of the bulk field corresponding this correlator.
