Issue when using UsePaveBasis in TID

[andlessa]

Hi,

I'm trying to compute a 4-point function at 1-loop (box diagram) and after simplifying the function I try to do the tensor decomposition in terms of the PaVe functions using UsePaVeBasis->True.
However some of the terms in the output still contain the loop momentum and the propagators containing the loop variable.
Is this the expected behavior? Am I missing something here?
Here is the output:

Hi,

just add the option ToPaVe->True to TID.

But in this case I will get the decomposition in terms of scalar integrals, right? What I would like is the decomposition in terms of the tensor integrals, so the resulting expression is not so messy.

No, having both options set to True will give you exactly what you want. Just try it ;) Am 6. April 2023 17:31:01 UTC schrieb Andre Lessa ***@***.***>:
