t-channel Feynman Diagram is not coming

Hi,

The less trivial reason is that the developer of the model indicates that such diagram is negligible due to it’s coupling constant.
you can try to add QED<=99 to your process definition to see if this is the reason.

Otherwise, I would need much more details to be able to help.

Cheers,

Olivier

Only s-channel diagram is coming. t-channel diagram is not coming. There are two vertices available for the t-channel diagram. I have checked, this two vertices are there. But I am not getting why the t-channel diagram is not coming.

Hi Olivier,
                thanks for the quick response.

>>you can try to add QED<=99 to your process definition to see if this is the reason.

yes, this the reason.
