Comix PS_Channel abort with EFT dim8 UFO model
With the attached UFO model one can generate two EFT contributions: the linear (i.e. interference between EFT and SM diagrams) and the quadratic (i.e. squared EFT). While the linear one works fine, the quadratic one dies during integration with an "Internal error" from the Comix PS_Channel
. Both run cards are attached, the diagrams generated from them look fine at first glance. Any idea why Comix dies here, @shoeche?
