Detailed Description

A class to parametrise missingET.

This class serves as an intrinsic parametrisation of the missingET vector, which is defined such that it has the same properties as the other final state objects like electrons and jets. Furthermore, the user can decide which class of muons he wants to take into account for the total missing energy vector.

Constructor & Destructor Documentation

ETMiss::ETMiss ( MissingET *  met)


The constructor takes a missing ET object as it is defined within Delphes. The energy is then automatically smeared by adding a vector with random magnitude Gauss(m=20 GeV, s = 1 GeV) [chosen empirically] and uniformly random direction.

Member Function Documentation

void ETMiss::addMuons ( std::vector< Muon * >  muons)

Add muons to missingET calculation.

Since there is no unique way to define how muons are taken into account in the missingET calculation, thy have to be added manually by the user. With this general function, one just has to declare which set of muons one wants to take into account.

muonsA std::vector of Muon objects that should be added.
