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:

• TVector2
• TVector3
• TLorentzVector
• TLorentzRotation
• TQuaternion
• TRotation

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. More...
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. More...
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. More...
class	TVector2
class	TVector3
