4. Resolution Fitted with the quadratic sum without 80GeV: This symbol represent a quadratic sum (1) With 80GeV (2) Without 80GeV The resolution is dominated by the noise term (528% )? 4

5. I represented the resolution as a function of 1/sqrt(E) and I fited with a linear function For the two cases respectively with and without 80GeV 5

6. (1) Resolution Fitted with the quadratic sum: (1)(2) (2) Resolution as a function of 1/sqrt(E) (Energies 20-40-60GeV) 6
