我们分析了六维“线性颤振”超对称共形场论(SCFT’s)重力对偶周围自旋-2激发的质谱。我们证明了对于整个引力解族,它满足一个界,该界对应于对偶场论算符的标度维的统一界。我们确定了属于短多重态的激发的质量,并且对于某些重力解,我们得到了Kaluza-Klein模和相应的质谱,完整而明确。最后,我们讨论了对偶算子在SCFT的有效描述方面的直观图像。
A bstractWe analyze the mass spectrum of spin-2 excitations around the gravity duals of “linear quiver” supersymmetric conformal field theories (SCFT’s) in six dimensions. We show that for the entire family of gravity solutions it satisfies a bound which corresponds to a unitarity bound for the scaling dimension of the dual field theory operators. We determine the masses of excitations which belong to short multiplets, and for certain gravity solutions we obtain the Kaluza-Klein modes and the corresponding mass spectrum, fully and explicitly. Finally, we discuss an intuitive picture of the dual operators in terms of the effective descriptions of the SCFT’s.
