Classical c=1 Tachyon Scattering and 1/2-BPS Correlators
arXiv:hep-th/0701086 · doi:10.1143/PTP.117.795
Abstract
We study the correlator of chiral primary operators in $\Ncal$=4 super Yang-Mills theory in large 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.
