Detailed Description

template<class AElectron, class AMuon, class AJet, class AMet>
class hitfit::RunHitFit< AElectron, AMuon, AJet, AMet >

Template class of experiment-independent interface to HitFit. This class is intended to be used inside the programming environment of a specific experiment, where each type of physics objects has its own class/type. For using HitFit with generic four-vector classes, user can't use this class and have to use the Top_Fit class directly. The reason is: this class is designed assuming electron and muon are represented by different object type, a situation which is guaranteed to happen in any experiments. The class contains some static integer constants to limit the maximum amount of jets in an event before fitting. See the description of those constants for details. The numbers of permutations for $t\bar{t}$ and $t\bar{t}H$ as a function of the number of jets $N_{\mathrm{jet}}$ in the event for a few values of are.

$N_{\mathrm{jet}}$	$N_{t\bar{t}}$	$N_{t\bar{t}H}$
4	24	N/A
5	120	N/A
6	360	360
7	840	2520
8	1680	20160

If adjusting the limits defined by the static constants is desired, then please the following formulas.

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:

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

Parameters

AElectron	The typename of the electron physics object class to be translated into HitFit's Lepjets_Event_Lep.
AMuon	The typename of the muon physics object class to be translated into HitFit's Lepjets_Event_Lep.
AJet	The typename of the jet physics object class to be translated into HitFit's Lepjets_Event_Jet.

◆ AddJet()

template<class AElectron , class AMuon , class AJet , class AMet >

void hitfit::RunHitFit< AElectron, AMuon, AJet, AMet >::AddJet	(	const AJet &	jet,
		bool	useObjRes = `false`
	)

inline

Add one jet into the internal event. This function will do nothing if the internal event has already contained the maximally allowed number of jets.

Explanation about this function: This function does not directly add the jet into the internal event. Rather, this function store the jet in an internal array. The reason is: jet energy correction and resolution depends on the jet type in the permutation. Therefore RunHitFit will only add jet into the event after a specific jet permutation has been determined. This is done in the FitAllPermutation function().

Parameters

jet	The jet to be added into the internal event.
useObjRes	Boolean parameter to indicate if the user would like to use the resolution embedded in the object, and not the resolution read when instantiating the class.

Before a fit to a particular permutation is done, this class convert the jets in this array into Lepjets_Event_Jet format, taking into consideration the assumed jet type and applying the appropriate jet energy correction.
