Problem with computing decay width of p > t z > w+ b l+ l-
Hi, I am trying to get the decays of the process to compute branching rations,
I am using the following commands
import model topFCNC_UFO
generate p > t z > l+ l- w+ b
output
launch -i
calculate_
I am faced with this error at the end of computation

WARNING: update the strong coupling value (alpha_s) to the value from the pdf selected: 0.13

What seems to be the issue here, can you point it out? since i Think I do have correct masses in the param card
For context, here is the param card
