Insights on Pentaquarks through Gauge/String Duality

In the framework of the gauge/string duality, I will discuss three aspects of pentaquark systems: 1. The ground state of the $Q\bar{Q} qqq$ system. 2. The possible reason for the difficulty of observing the $QQqq\bar{q}$ pentaquark. 3. Generalized baryon vertices and their implications for pentaquarks.
