Infrared Duality in Unoriented Pseudo del Pezzo

Abstract

We study the orientifold projections of the $N = 1$ superconformal field theories describing D3-branes probing the Pseudo del Pezzo singularities PdP $_{3 b}$ and PdP $_{3 c}$ . The PdP $_{3 c}$ parent theory admits two inequivalent orientifolds. Exploiting $a$ maximization, we find that one of the two has an $a$ -charge smaller than what one would expect from the orientifold projection, which suggests that the theory flows to the fixed point in the infrared. Surprisingly, the value of $a$ coincides with the charge of the unoriented PdP $_{3 b}$ and we interpret this as the sign of an infrared duality.
