Description
The Light Front formulation of quantum field theories has been put to use in the study of hadron physics in the last few decades. However, like in the conventional formulation, Light Front field theories too are fraught with infrared divergences in the presence of massless particles. We employ the coherent state formalism to deal with these divergences at the amplitude level for Light Front QCD in the perturbative regime. We firstly obtain the coherent states, in Light Front formulation, to be used in calculating the transition amplitudes for the processes $e^{+}e^{-}\rightarrow 2\;jets$ and $e^{+}e^{-}\rightarrow 3\;jets$. We then discuss the cancellation of infrared divergences - both soft and collinear - for these processes at the amplitude level.
