Legacy Physics Classes

Legacy physics classes.

Legacy physics vector package

The references below are for legacy use cases.

Please use the current physics classes as described in the Manual instead of these legacy classes:

Legacy statistics classes

Please consider using RooStats instead of TRolke. For non-trivial cases use RooStats instead of TFeldmanCousins. TRobustEstimator and TGenPhaseSpace have no current alternatives.

Classes

class  TFeldmanCousins
 

Legacy Code

TFeldmanCousins is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TFeldmanCousins might still be a valid solution. Consider switching to RooStats for non-trivial cases.

class  TGenPhaseSpace
 

Legacy Code

TGenPhaseSpace is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TGenPhaseSpace might still be a valid solution. No alternative classes are currently available.

class  TLorentzRotation
 

Legacy Code

TLorentzRotation is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TLorentzRotation might still be a valid solution. Consider using instead ROOT::Math::LorentzRotation.
The TLorentzRotation class describes Lorentz transformations including Lorentz boosts and rotations (see TRotation) More...
 
class  TLorentzVector
 
class  TQuaternion
 

Legacy Code

TQuaternion is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TQuaternion might still be a valid solution. Consider using instead ROOT::Math::Quaternion.
Quaternion is a 4-component mathematic object quite convenient when dealing with space rotation (or reference frame transformation). More...
 
class  TRobustEstimator
 
class  TRolke
 

Legacy Code

TRolke is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TRolke might still be a valid solution. Consider switching to RooStats.
This class computes confidence intervals for the rate of a Poisson process in the presence of uncertain background and/or efficiency. More...
 
class  TRotation
 

Legacy Code

TRotation is a legacy interface: there will be no bug fixes nor new developments. Therefore it is not recommended to use it in new long-term production code. But, depending on the context, using TRotation might still be a valid solution. Consider using instead ROOT::Math::Rotation3D.
