    A A problem about branch cut in contour integral

    Hello. I'm sorry to reply you lately as I've studied complex analysis further to understand what you said. I'm afraid that I'm still not understanding your point. It looks you said that a domain of w(z) = z1/2 is restricted to make w(z) continuous. Could you please give me details of how the...

    A A problem about branch cut in contour integral

    Hello. I have a difficulty to understand the branch cut introduced to solve this integral. \int_{ - \infty }^\infty {dp\left[ {p{e^{ip\left| x \right|}}{e^{ - it\sqrt {{p^2} + {m^2}} }}} \right]} here p is a magnitude of the 3-dimensional momentum of a particle, x and t are space and time...
