Z+jets matching with misset cut 100 GeV
Hi,
I have a question regarding matching in Z (decaying to nu nu) + 4 jets process (Z+1,2,3,4 jets) , where I generate them with a misset cut of 100 Gev, applied in the MadGraph run_card. The generation was done in the following manner:
define j = j b b~
generate p p > z j ALL=99, z > vl vl~
add process p p > z j j ALL=99, z > vl vl~
add process p p > z j j j ALL=99, z > vl vl~
add process p p > z j j j j ALL=99, z > vl vl~
Matching was performed with xqcut varying in the range 20 - 110 GeV (with MLM matching).
I am facing the following problems:
1. Although I have not generated any Z+0 jet process, still I observe a 0 jet distribution in the DJR plots. It would be extremely helpful if you could explain that or provide a suitable reference regarding this.
2. The DJR2 plot doesn't seem to be continuous and I am getting a significant bump in the plot, the position of which varies with the value of xqcut.
3. DJR3 and DJR4 plots are fine. However the DJR1 is terribly bumpy. I was wondering whether I should be bothered with the DJR1 plot as I have not generated any Z+0 jet process?
4.Would you recommend any xqcut range which will be suitable for the above mentioned process?
Thank you for your help...
