Box diagram calculation (Kaon mixing)

[QUOTE="Natthawin Cho, post: 5450825, member: 591692"] I am trying to calculate box diagram of Kaon mixing by follow the "CP Violation" book. Now, I arrived at equation (B.8) and I have problem with getting equation (B.12). [tex]F(x_\alpha,x_\beta)=\dfrac{1}{(1-x_\alpha)(1-x_\beta)}(\dfrac{7x_\alpha x_\beta}{4}-1)+\dfrac{x_\alpha^2lnx_\alpha}{(x_\beta-x_\alpha)(1-x_\alpha)^2}(1-2x_\beta+\dfrac{x_\alpha x_\beta}{4})+\dfrac{x_\beta^2lnx_\beta}{(x_\alpha-x_\beta)(1-x_\beta)^2}(1-2x_\alpha+\dfrac{x_\alpha x_\beta}{4})[/tex] I got a lot of terms with high order of m[SUB]W[/SUB] (m[SUB]W[/SUB][SUP]2[/SUP], m[SUB]W[/SUB][SUP]4[/SUP], m[SUB]W[/SUB][SUP]6[/SUP], ...) while there is no m[SUB]W[/SUB] term in the book. I checked the integral over Feynman parameter twice. [/QUOTE]
