Description
We calculate non-global logarithms at finite $N_c$ for the hemisphere mass distribution in $e^+e^-\to q \bar{q}$ at single logarithmic accuracy up to fifth order in the coupling constant. Our results indicate the possibility of resummation of these logarithms to all orders into an exponential form. We compare our findings to those reported in the literature at large $N_c$ and find agreement. We also compare our results with numerical all-orders resummation at lagre $N_c$ and discuss the importance of finite $N_c$ corrections on the said distribution.
