Some test failed FKS

Asked by Antonio Sandroni

Hi, im running p p > w+ w- [QED] --sudakow at 100 Tev with some cuts on rapity, inv.mass. transverse momentum and deltaR
I have this error but i don't think its caused by these.
I have set all widths to zero.

INFO: Result for check_poles:
INFO: Poles successfully cancel for 20 points over 20 (tolerance=1.0e-05)
INFO: Result for check_sudakov:
INFO: P0_aa_wpwm
INFO: Result for test_ME:

Ciao Antonio,
First, for this process, you should kill/veto b quarks in the initial state, otherwise, you will have resonant top quarks. Are you keeping b quarks?

Then, it may be that given the high energy and the cuts, tests are failing because of numerical instabilities, which won't cause harm during actual runs.
To do so, you can increase the tolerance to consider tests as successful ones.
Edit SubProcesses/test_soft_col_limits.f
and increase
 18 double precision max_fail
 19 parameter (max_fail=0.3d0)

to something like 0.5 or so

Let me know

cheers,

Marco
