Within the Matrix Product Formalism we have already introduced a
multi-species exclusion process [1],[2], in which different particles hop
with different rates and fast particles stochastically overtake slow
ones. In this letter we show that on an open
chain, the master equaiton of this process can be exactly solved via
the coordinate Bethe ansatz. It is shown that the N-body S-matrix of this
process is factorized into a product of two-body S-matrices, which in turn
satisfy the quantum Yang-Baxter equation (QYBE). This solution is to our
knowledge, a new solution of QYBE.
