Abstract: We study the null brane and its quantization. We show that there are 2 important constraint classes. One is the extension of the level-matching constraint to the brane case. The other constraint, which is specific to the brane is more involved and poses the main source of difficulty in quantizing the null brane. We have found three classes of physical states, depending on their eigenvalues under a level-matching operator, that can satisfy the constraints. The trivial one constitutes zero-eigenstates of the level-matching operator, which we call Class-1. We show that this class trivially satisfies the brane-sourced constraint as well as level-matching. There exists another, more involved and interesting class of states that are not zero-eigenstates of the level-matching operators. We study their structure and also describe how we can satisfy the brane-sourced constraint for these states.
