bool hitfit::Top_Fit_Args::_do_higgs_flag [private]

If TRUE, then fit a $t\bar{t}H$ events. Otherwise fit $t\bar{t}$ event.

double hitfit::Top_Fit_Args::_mtdiff_max_cut [private]

Reject event before fit if the mass difference between leptonic top and hadronic top is larger than this value, in GeV.

int hitfit::Top_Fit_Args::_nkeep [private]

The number of Fit_Results from different jet permutations to keep. It is recommended that the number is set accordingly to the maximally allowed number of jets in the event. The number for possible permutations, $N_{t\bar{t}}$ , as a function of number of jets, $ n $ , for $t\bar{t}$ event is given by:

$N_{t\bar{t}}(n) = \frac{n!}{(n-4)!};~ n \ge 4$

The number for possible permutations, $N_{t\bar{t}H}$ , as a function of number of jets, $ n $ , for $t\bar{t}H$ is given by:

$N_{t\bar{t}}(n) = \frac{n!}{(n-6)!2!};~ n \ge 6$

bool hitfit::Top_Fit_Args::_print_event_flag [private]

If TRUE, then print the event after the fit. Otherwise don't print.

bool hitfit::Top_Fit_Args::_solve_nu_tmass [private]

If TRUE, then solve the neutrino longitudinal $ z- $ component by requiring the leptonic top have the same mass as the hadronic top. If FALSE, then solve the neutrino longitudinal $ z- $ component by requiring the lepton and neutrino mass to equal to the mass of the $ W- $ boson $m_{W}$ .
