A Matrix Model for Baryons and Nuclear Forces

Understand

We propose a new matrix model describing multi-baryon systems.

• We derive the action from open string theory on the wrapped baryon vertex D-branes embedded in the D4-D8 model of large N holographic QCD.
• The positions of k baryons are unified into k x k matrices, with spin/isospin of the baryons encoded in a set of k-vectors.
• Holographic baryons are known to be very small in the large 't Hooft coupling limit, and our model offers a better systematic approach to dynamics of such baryons at short distances.
