Detailed Description

These should give you access to xAOD::Iso::topoetcone20, 30, 40 and ptcone20, 30, 40.

They are only correct in the derivations, they will be wrong in the primary xAOD.

It performs an absolute cut on the quantity you specify. If you need more fancy things, we should implement them. Don't you want to look at using RelativePTVarCone instead though?

Constructor & Destructor Documentation

AbsoluteIsolationDC14()

top::AbsoluteIsolationDC14::AbsoluteIsolationDC14	(	const xAOD::Iso::IsolationType	type,
		double	value
	)

Absolute cut on topoetcone or ptcone.

Construct with something like:

new IsolationDC14(xAOD::Iso::topoetcone20, 5000.)

We didn't bother implementing the loose selection yet. I left that as an exercise for the reader.

Parameters

type	I think xAOD::Iso::topoetcone20, 30, 40 and ptcone20, 30, 40 are allowed.
value	A number in MeV.

Member Function Documentation

passSelection()

bool top::AbsoluteIsolationDC14::passSelection ( const xAOD::IParticle &  p ) const

overridevirtual

For applying isolation cuts to the analysis (tight) lepton.

Note that you must implement this otherwise it wont compile. Ha.

Parameters

p	The lepton

Returns

True if it passes the isolation cuts, false otherwise.

Implements top::IsolationBase.

    //electrons
    if (p.type() == xAOD::Type::Electron) {
      float iso = 0.;
      const xAOD::Electron* el = dynamic_cast<const xAOD::Electron*>(&p);
      bool exists = el->isolationValue(iso, m_type);
      return exists && iso > m_cutvalue;
    }
 
    //muons
    if (p.type() == xAOD::Type::Muon) {
      float iso = 0.;
      const xAOD::Muon* mu = dynamic_cast<const xAOD::Muon*>(&p);
      bool exists = mu->isolation(iso, m_type);
      return exists && iso > m_cutvalue;
    }
 
    throw std::runtime_error("TopObjectSelectionTools::IsolationTools::AbsoluteIsolationDC14: Not an electron or muon");
  }

passSelectionLoose()

bool top::AbsoluteIsolationDC14::passSelectionLoose ( const xAOD::IParticle &  p ) const

overridevirtual

Implement me!

Implements top::IsolationBase.

Definition at line 49 of file IsolationTools.cxx.

                                                                             {
    return true;
  }

print()

void top::AbsoluteIsolationDC14::print ( std::ostream &  os ) const

overridevirtual

Because people like to know what isolation cuts they're applying.

Parameters

os	Where to print things to, e.g. msg stream.

Implements top::IsolationBase.
