The Holographic Life of the $\eta'$
In the string holographic dual of large-N_c QCD of Kruczenski et al, the eta' meson is massless at infinite N_c, and dual to a collective fluctuation of N_f D6-brane probes in a supergravity background. We show here that it aquires a mass of order N_f/N_c, consistent with the Witten-Veneziano f...
