### 06/09/2019

This was ENFPC 2019 week. While there, I learned how to make my DM particle look like a neutrino for the MadGraph misset generation cut. Now I can run only 5k events with a MET restriction, instead of 300k events without MET restriction, and obtain the same result. The change was in the SubProcess/setcuts.f file, where the line if (abs(idup(i,1,iproc)).eq.1000022) is_a_nu(i)=.true. needs to be added after the same lines but with the neutrinos PDG codes. This will improve my results a lot.

Today I did what Thiago told me to a couple of weeks ago. For each value of m_{d_{H}} and m_{Z'}, I needed to find the number of events N that gave me almost 95% CLs (actually 1-\<CLs\>) using the TLimit ROOT class, and calculate the cross section for that value using the formula \sigma = N/(lumin \ eff)*. Then I would calculate the cross section using the number of events that I've found for each m_{d_{H}} or m_{Z'} concerning each BG, and compare both. The graphs are below. Everything that is above the blue line, is excluded with 95% certainty.
