ETA Graphs for different EFT parameters

The effect of varying different Higgs c coupling values has been investigated. I varied cHW, cWW, and then both simultaneously. The c coefficient values for the SM case are 0. For each comparison there are 3 plots: there is the original unscaled histogram of the pseudorapidity; one scaled to make the y axis d(simga)/d(eta) by using a factor of (crosssection) / (integral under the SM histogram) on the original histogram; and then one scaled to make the y axis 1/sigma d(simga)/d(eta) by using a factor of 1 / (integral under the SM histogram) on the original histogram. 100,00 events were generated for each coupling value. The Standard Model line on each comparison plot had a cross section of 0.028427 pb (to 6 significant figures) and had 99797 entries from the original 100,000 generated.

Graphs of the electron pseudorapidity for three values of cHW: 0.1, 0.075, and 0.05. The cross sections were 0.092673, 0.060957, 0.039631 pb respectively (to 6 decimal places). All other coefficients were set at 0.
