Classical c=1 Tachyon Scattering and 1/2-BPS Correlators
Abstract
We study the correlator of chiral primary operators in =4 super Yang-Mills theory in large N limit. Through the free fermion picture, we map the gauge group rank and R-charges in SYM to the Fermi level and tachyon momenta, respectively, in the c=1 matrix model. By doing so, it is seen that half-BPS correlators are reproduced by tree-level tachyon scattering amplitudes.
