Holographic nucleons in the nuclear medium

Article history: Received 16 March 2015 Received in revised form 28 April 2015 Accepted 29 April 2015 Available online 4 May 2015 Editor: M. Cvetič We investigate the nucleon’s rest mass and dispersion relation in the nuclear medium which is holographically described by the thermal charged AdS geometry. With this background, the chiral condensate plays an important role to determine the nucleon’s mass in both the vacuum and the nuclear medium. It also significantly modifies the nucleon’s dispersion relation. The nucleon’s mass in the high density regime increases with density as expected, while in the low density regime it slightly decreases. We further study the splitting of the nucleon’s energies caused by the isospin interaction with the nuclear medium. © 2015 The Authors. Published by Elsevier B.V.
