Thank you very much for your effort! It provides more insight to the question.

Thanks, but the cosine term is important for my case, as my problem has oscillatory behaviour

Thank you very much for all the replies! Indeed it is a very difficult problem. I find that Mathematica can also give an exact result if I omit the exponential term.

I encounter a very complicated integral in my research project, and it can only be done by complex contour integral. I have tried many other methods like integration by parts and substitution, which all fail. In the integral, all a, alpha and beta are positive real numbers. I have found a...
