In this paper, we focus on computing the higher slope Hasse polynomials of L-functions of certain exponential sums associated to the following family of Laurent polynomials f(x1,,xn+1)=i=1naixn+1(xi+1xi)+an+1xn+1+1xn+1, where aiFq, i=1,2,,n+1. We find a simple formula for the Hasse polynomial of the slope one side and study the irreducibility of these Hasse polynomials. We will also provide a simple form of all the higher slope Hasse polynomials for n=3, answering an open question of Zhang and Feng.
