Crash in ttbar production run

[Frank Siegert]

After successful running of generating 1000 events, I started generating large amount of events, and then I found it failed. Could you look at my setting and log file?

Also, I have a separate question. If I use "NJetFinder", Would it be working only for QCD light jet, or also working for jets from heavy particles such as top?

Thanks, Seung

Hi Seung,

could you please test whether this problem has been fixed in version 1.2.1, which has just been released?

And if you still encounter problems, please post the normal screen output of the Sherpa run as well.

Thanks, Frank

I tried the new version, but still I have the crash. I am sending you the Run.dat and the normal screen output

of the Sherpa run. Could you take a look at them?

Thanks, Seung

Hi Seung,

I checked your setup, however, setting the b-quarks massive in order for the top-selector I set up for you before to work and and furthermore setting ORDER_EW = 4 in the process setup.

I see a few error messages from the phase-space generator, that however we can ignore for the time being. Having generated 5k events with that setup I didn't get a crash yet. Do you really intend to have the electro-weak contributions for the ttbar core process included or was it more by mistake that you commented the coupling constraint out?

Cheers, Steffen
