Considering the small jet radius limit $(R\\ll 1)$ we factorize the scattering cross section into a partonic cross section, the fragmentation function to a jet, and the jet mass distribution function. The decoupled jet mass distributions for quark and gluon jets are well-normalized and scale invariant. And they can be extracted from the ratio of two scattering cross sections such as $d\\sigma/(dp_T^JdM_J^2)$ and $d\\sigma/dp_T^J$.
