چکیده	In this paper, we use the noncritical string/gauge duality to calculate the decay widths of large-spin mesons. Since it is believed that the string theory of QCD is not a ten-dimensional theory, we expect that the noncritical versions of ten-dimensional black hole backgrounds lead to better results than the critical ones. For this purpose we concentrate on the confining theories and consider two different six-dimensional black hole backgrounds. We choose the near-extremal AdS 6 model and the near-extremal KM model to compute the decay widths of large-spin mesons. Then, we present our results from these two noncritical backgrounds and compare them together with those from the critical models and experimental data.
