Hi!

I'm trying to generate a BSM process with a loop. p p > scalar scalar

The model works on other machines, but i'm getting the following error:

Hi,

This bug is solved in 2.6.5, even if we still faced some particular case that were still crashing in 2.6.5.
In that case, you might want to try the development version (future 2.6.6)

A work around is to change the dynamical scale (to either fix scale or to another dynamical scale)

Cheers,

Olivier

Hi,

Thanks! Changing the dynamical scale seems to work. I'm currently using the version 2.6.4.

Cheers,

Tom
