CELER_FUNCTION void celeritas::boost ( Real3 const &  v, FourVector *  p  )

inline

Perform the Lorentz transformation along a boost vector.

The transformation ( \( \Lambda^{\alpha}_{\beta} \)) along the boost vector ( \( \vec{v} \)) for a four-vector \( p^{\beta} \) is:

\[ p^{\prime \beta} = \Lambda^{\alpha}_{\beta} (\vec{v}) p^{\beta} \]

.

Todo:

: define a boost function that takes a second FourVector for reduced register usage
