1. in the above code add new TLorentzVector el3, el4 for the 3rd and 4th lepton and set their pt, eta phi, mass. 

2. Add these two vectors to get a new vector TLorentzVector zCandidate2.

3. Add the two vectors zCandidate and zCandidate2 to get a new TLorentzVector Higgs.

4. DEfine a new histogram H_zz 

   1. TH1F* H_zz = new TH1F("H_zz", "ZZ candidate invariant mass", 200, 0, 300);

5. Fill the H_zz histogram with HIggs mass.  (using Higgs.M() )

6. Write the H_zz histogram. 

7. open the output file and paste the Z_ee and H_zz histograms in your HW file.

Followed instructions.

Got data on higgs mass - 124 average

Added 3rd histogram for 2nd Z
