WLWL > WL WL scattering

Did you set the width to zero? and/or use the complex mass scheme for the computation?

Cheers,

Hello Sir,
 I didn't set the width zero. Also I have not used any complex mass scheme. I am using default SM in Madgraph.

Then you certainly break gauge invariance/lorentz invariance for your computation and this should explains your result.

Hello Sir,
  I got your points. But after setting width to be zero, still I have the same problem. I wold be grateful if you can send me one of your example program for this process.

Thanks

I do not have any example program.
