I have tried to use the regular formula for the n-point function, when you derive Z[J] n times in relation to J(t_1)...J(t_n) and after applies J=0, but it doesn't make sense for me, since all the n-point functions will be zero.

Actually, I think this particular Z[J] pretty strange because its integrals are not linear in J(t) as I used to see.

So, could someone give me a hint?

Thanks!
