$({\alpha }^{\prime }{)}^4$ Corrections in Holographic Large N_c QCD and $\pi -\pi$ Scattering

R. Parthasarathy, K. S. Viswanathan

We calculate the ${{\alpha }^{\prime }}^4$ corrections to the non-Abelian DBI action on the D8-brane in the holographic dual of large N_c QCD proposed by Sakai and Sugimoto. These give rise to high…
