Explicit Flavor Symmetry Breaking and Holographic Compact Stars

다국어 초록 (Multilingual Abstract)

We study the effects of flavor symmetry breaking on holographic dense matter and compact starsin the D4/D6 model. To this end, two light flavors and one intermediate mass flavor are considered.
For two light quarks, we investigate how the strong isospin violation affects the propertiesof holographic dense matter and compact stars. We observe that quark-antiquark condensates areflavor dependent and show interesting behavior near the transition from dense matter with onlyone flavor to matter with two flavors. An intermediate mass quark is introduced to investigate therole of the third flavor. The mass-radius relations of holographic compact stars with three flavorsshow that the mass-radius curve changes drastically at a transition density from which the thirdflavor begins to appear in the matter.
