## Detailed Description

FuzzyTheta implements fuzzy cut prescriptions.

The interfaces defined for FuzzyTheta.

Definition at line 57 of file FuzzyTheta.h.

## ◆ clone()

 virtual IBPtr ThePEG::FuzzyTheta::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

## ◆ fullclone()

 virtual IBPtr ThePEG::FuzzyTheta::fullclone ( ) const
protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns
a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

## ◆ Init()

 static void ThePEG::FuzzyTheta::Init ( )
static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

## ◆ operator=()

 FuzzyTheta& ThePEG::FuzzyTheta::operator= ( const FuzzyTheta & )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

## ◆ overlap()

 virtual double ThePEG::FuzzyTheta::overlap ( double x, const pair< double, double > & box ) const
inlinevirtual

Return the overlap integral of the delta approximation with the given box and center.

This default version assumes a box approximation. All values are assumed to be in units of the width considered.

Definition at line 92 of file FuzzyTheta.h.

## ◆ persistentInput()

 void ThePEG::FuzzyTheta::persistentInput ( PersistentIStream & is, int version )

Function used to read in object persistently.

Parameters
 is the persistent input stream read from. version the version number of the object when written.

## ◆ persistentOutput()

 void ThePEG::FuzzyTheta::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters
 os the persistent output stream written to.

## ◆ support()

 virtual pair ThePEG::FuzzyTheta::support ( double x ) const
inlinevirtual

Return the (compact) support of the delta approximation considered, given its center value.

This default version assumes a box approximation. All values are assumed to be in units of the width considered.

Definition at line 82 of file FuzzyTheta.h.

## ◆ initFuzzyTheta

 ClassDescription ThePEG::FuzzyTheta::initFuzzyTheta
staticprivate

The static object used to initialize the description of this class.

Indicates that this is a concrete class with persistent data.
