Meson modes of probe D7-branes in Klebanov-Strassler background
Abstract
We examine the properties of 4-d bosonic and fermionic (mesons and mesinos) modes on D7-branes wrapped over Kuperstein 4-cycle of the Klebanov-Strassler background. The wave equations are derived in a convenient parameterization of the warped deformed conifold metric. The mass spectra, wave functions and couplings of bosonic modes are evaluated by means of semi-classical tools. We explore the possible existence of fermionic zero modes.
