class  Resolution

class  Row_Vector
 Row-vector class. CLHEP doesn't have a row-vector class, so HitFit uses its own. This is only a simple wrapper around Matrix that tries to constrain the shape to a row vector. It will raise an assertion if you try to assign to it something that isn't a row vector. More...
 
class  RunHitFit
 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. More...
 
class  Top_Decaykin
 A class to hold functions to calculate kinematic quantities of interest in $ t\bar{t} \to \ell + 4 \mathrm{jets} $ events. This class has no state, only static member functions. More...

class  Top_Fit_Args
 Hold on to parameters for the Top_Fit class. More...
 
class  Vector_Resolution
 Calculate and represent resolution for a vector of $p$, pseudorapidity $\eta$, and azimuthal angle $\phi$. An instance of this class holds three Resolution objects, one each for $p$, $\eta$, and $\phi$. In addition, we have a flag to indicate if the momentum resolution is in $p_{T}$ or $p$. This flag is set by appending [/et] at the end of the string. More...

◆ make_constraint_intermed() [2/2]

std::unique_ptr<Constraint_Intermed> hitfit::make_constraint_intermed ( std::string  s)

Helper function to parse input string s and construct the appropriate Constraint_Intermed instance. Returns null if the input string cannot be interpreted as a mass constraint.

The string should be either a numeric constant like

80.4

or a list of integers in parenthesis like

(1 2 4)

Leading spaces are ignored, as is text in a leading <> construction.

Parameters
sThe string to parse which contains information about the mass constraint.
Return:
Valid pointer to the appropriate type of constraint object, i.e. a Constraint_Intermed_Constant or a Constraint_Intermed_Labels.
NULL pointer if the input string cannot be interpreted as a mass constraint.
