A Novel (2+1)-Dimensional Model of Chiral Symmetry Breaking

Understand

We propose a new model of flavour chiral symmetry breaking in a (2+1)-dimensional defect gauge theory of strongly coupled fermions by introducing probe D5/anti-D5-flavour branes on the conifold.

• After working out the flavour brane embeddings at zero temperature, we thoroughly investigate the spectra of small fluctuations on the world volume of the flavour branes (meson spectrum) and conclude that they are free of tachyons.
• Thus the proposed probe brane embedding is stable.
• Moreover, we introduce finite temperature and an external magnetic field and study the thermodynamics of the resulting configurations.
