NLO EWK corrections to ttZ

Asked by Baptiste Ravina

Dear MadGraph experts,

I am trying to reproduce the results from section 6.3 of https://arxiv.org/pdf/1804.10017.pdf, namely the generation of ttZ NLO QCD and EWK corrections with

generate p p > t t~ z QED=3 QCD=2 [QCD QED]

Using MG v3.0.3 I however get an exception

Exception : program /Users/bravina/Documents/LocalMadGraph/MG5_aMC_v3_0_3/ttZ_EWK/SubProcesses/P0_gg_ttxz/ajob1 1 all 0 0 launch ends with non zero status: 1. Stop all computation

The debug log is pasted below, any help appreciated!
Thanks,
Baptiste

Dear Baptiste,

What are the error messages in the SubProcesses/P*/all_G*/log.txt files?

Hi Rikkert,

In P0_gg_ttxz/all_G1/log.txt I see

"Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG"

and

"ERROR in cuts.f: photon isolation is not working for mixed QED-QCD corrections".

And in P0_uxu_ttxz/all_G1/log.txt, only this latter error.

Cheers,
Baptiste

Hi Baptiste,

Ahh.. you have to remove the cut in the photon. I.e, set the ptgmin parameter in the run_card to a negative value. (Note that you can have photons in your final state in the real-emission contributions, hence you do not want to cut those away).

Best,
Rikkert

Hi Rikkert,

I changed the photon isolation block of my original run_card (in the main body of the ticket) to

  -1.0 = ptgmin ! Min photon transverse momentum
  -1.0 = etagamma ! Max photon abs(pseudo-rap)
  -1.0 = R0gamma ! Radius of isolation code
  1.0 = xn ! n parameter of eq.(3.4) in hep-ph/9801442
  1.0 = epsgamma ! epsilon_gamma parameter of eq.(3.4) in hep-ph/9801442
 False = isoEM ! isolate photons from EM energy (photons and leptons)

but the same error remains. What else did I miss?

Thanks,
Baptiste

Hi Baptists,

Sorry, there is a bug here. Instead of putting it to a negative value, you have to set ptgmin to 0 for it to work.

Hi Rikkert,

Thanks a lot, that worked! Is it possible to isolate from the output of the calculation what the various NLO_i correction terms are? Or should I run separately e.g.

generate p p > t t~ z QED=1 QCD=2 [QCD]
generate p p > t t~ z QED=1 QCD=2 [QCD QED]
generate p p > t t~ z QED=2 QCD=2 [QCD QED]
generate p p > t t~ z QED=3 QCD=2 [QCD QED]

and subtract? Also, do you have an FO analysis macro I could use to reproduce Figure 11 of the paper? (the Z pT distribution)

Cheers,
Baptiste

Hello Baptiste,

You can generate all those distributions in one go. See that analysis_HwU_general.f (in the FixedOrderAnalysis directory) for an (commented out) example (lines 11-18 and 376-389).

Best,
Rikkert

Thanks Rikkert!

I've tried the default analysis_HwU_general.f and it does give me the NLO/LO histogram for pT(Z). However, when I try to uncomment the lines you mention, I get

he compilation fails with the following output message:
    /usr/local/bin/gfortran -O -fno-automatic -ffixed-line-length-132 -c -I. -I../../FixedOrderAnalysis/ ../../FixedOrderAnalysis//analysis_HwU_general.f

Now I don't know Fortran, could you point me in the right direction?

hello Baptiste,

You have to change the declaration of the relevant array (i.e., the 'cc()' array) to enlarge it. Currently it's only 2 dimensional, but after uncommenting lines relevant to the orders, it becomes a much larger array. Moreover, the elements in the data array should be between slashes '/', just like it is in the current version. (See also https://docs.oracle.com/cd/E19957-01/805-4939/6j4m0vn85/index.html ).

(The warning regarding 'qperp' can be ignored).

best,
Rikkert

Hi Rikkert,

Yup, that works - thanks a lot for your invaluable help in getting this setup running!

Cheers,
Baptiste
