Heavy-light mesons from the AdS/CFT correspondence

Erdmenger, J., Grosse, J. and Evans, N. (2007) Heavy-light mesons from the AdS/CFT correspondence Journal of High Energy Physics, 1, p. 98. (doi:10.1088/1126-6708/2007/01/098).

Record type: Article


We propose a holographic description of heavy-light mesons, i.e. of mesons containing a light and a heavy quark. In the semi-classical string limit, we look at the dynamics of strings tied between two D7 branes. We consider this setup both in an AdS background and in the non-supersymmetric Constable-Myers geometry which induces chiral symmetry breaking. We compute the meson masses in each case. Finally we discuss the results relevance for phenomenological comparison to the physical b-quark sector.
