我们研究了描述D3-膜的N= 1超共形场论的orientifold探测悬夹点奇点，以及由SPP的特定orbifold Zn获得的非手征理论的orientifold。我们发现，这些模型实现了一个机制类似于最近发现的一个复杂的卡-丘锥的orientifold的伪德尔佩佐表面PdP 3c：他们都流到一个新的IR固定点，使值的a-电荷是小于一半的定向理论。我们还发现a的值与环面奇点L（n，n，n）的特定定向折叠的荷相一致，其中n= 3 n/2（n为偶数）或L（n，n+ 1，n）的特定定向折叠的荷相一致，其中n=（3 n − 1）/2（n为奇数），这表明IR对偶的存在。
We study the orientifold of the N= 1 superconformal field theories describing D3-branes probing the Suspended Pinch Point singularity, as well as the orientifolds of non-chiral theories obtained by a specific orbifold Zn of SPP. We find that these models realize a mechanism analogous to the one recently found for the orientifold of the complex Calabi-Yau cone over the Pseudo del Pezzo surface PdP3c: they all flow to a new IR fixed point such that the value of the a-charge is less than half the one of the oriented theory. We also find that the value of a coincides with the charge of specific orientifolds of the toric singularities L (n, n, n) with n= 3n/2 for n even or L (n, n+ 1, n) with n=(3n− 1)/2 for n odd, suggesting the existence of an IR duality.
