Header Files for Each Class

• SpaceVector.h
• UnitVector.h
• LorentzVector.h
• EulerAngles.h
• AxisAngles.h
• Rotation.h
  Includes related classes:

  Rotation

  RotationX

  RotationY

  RotationZ

• LorentzTransformation.h
  Includes related classes:

  LorentzTransformation

  LorentzBoost

  LorentzBoostX

  LorentzBoostY

  LorentzBoostZ

• PhysicsVectors.h
  Aggregate header for the entire package --
  Equivalent to including all the above headers.

Header Files for Special Purposes

• CLHEP Compatibility headers:
  • HepThreeVector.h
  • HepLorentzVector.h
  • HepRotation.h
  • HepLorentzRotation.h
  Allows user with CLHEP Vector code to use PhysicsVectors by including these headers.
  These four classes inherit from the respective PhysicsVectors classes so all the functionality extensions are available.
• PlaneVector.h
  Basic functionality for vectors in the X-Y plane.
• PhysVec.h
  Notational conveniences
  
  Not yet available:
• PV-LA.h
  Header smoothly connecting the PhysicsVectors package with the ZOOM LinearAlgebra package.
  Allows working with Matrices and SpaceVectors, Rotations, and so forth in a coordinated way.

Features Recently Implemented

• LorentzTransformation class to represent an abstract Lorentz transformation that may be combined and used on multiple 4-vectors. The header file also provides specialized classes LorentzBoost, LorentzBoostX, LorentzBoostY, and LorentzBoostZ.
• PlaneVector class to represent a 2-D vector in the X-Y plane.
• CLHEP Compatibility headers to support trivial migration of existing code.
• Notational convenience header PhysVec.h.

Features Not Yet Available

Extensions to support geometric objects such as TangentVectors (vectors associated with a point in space) and Point, Line, Plane have been specified but will not be part of this phase of the package.

• Presented at May 1998 ZOOM Mini-workshop:
  Detailed Comparison with CLHEP Vectors.
• Presented at CDF January 21. This talk, with very minor differences, is the same as was presented at the D0 CGAS meeting in late 1997.
