set the boost beta as 3 components
get beta of the boots as 3 components
get Lorentz rotation corresponding to this boost as an array of 16 values
Assuming the representation of this is close to a true Lorentz Rotation, but may have drifted due to round-off error from many operations, this forms an "exact" orthosymplectic matrix for the Lorentz Rotation again.
apply bosost to a PxPyPzE LorentzVector
========== Constructors and Assignment ===================== Default constructor (identity transformation)
{ SetIdentity(); }
Construct given a three Scalars beta_x, beta_y, and beta_z
{ SetComponents(beta_x, beta_y, beta_z); }
Construct given a beta vector (which must have methods x(), y(), z())
{ SetComponents(beta); }
Construct given a pair of pointers or iterators defining the beginning and end of an array of three Scalars to use as beta_x, _y, and _z
{ SetComponents(begin,end); }
The compiler-generated copy ctor, copy assignment, and dtor are OK. Assign from an axial pure boost
{ return operator=(Boost(bx)); }
======== Components ============== Set components from beta_x, beta_y, and beta_z
Get components into beta_x, beta_y, and beta_z
Set components from a beta vector
{ SetComponents(beta.x(), beta.y(), beta.z()); }
