G4double G4INCL::KinematicsUtils::momentumInCM ( Particle const *const  p1,
Particle const *const  p2 
)

gives the momentum in the CM frame of two particles.

The formula is the following:

\[ p_{CM}^2 = \frac{z^2 - m_1^2 m_2^2}{2 z + m_1^2 + m_2^2} \]

where $z$ is the scalar product of the momentum four-vectors:

\[ z = E_1 E_2 - \vec{p}_1\cdot\vec{p}_2 \]

Parameters
p1pointer to particle 1
p2pointer to particle 2
Returns
the absolute value of the momentum of any of the two particles in the CM frame, in MeV/c.

G4double G4INCL::KinematicsUtils::momentumInLab ( Particle const *const  p1,
Particle const *const  p2 
)

gives the momentum in the lab frame of two particles.

Assumes particle 1 carries all the momentum and particle 2 is at rest.

The formula is the following:

\[ p_{lab}^2 = \frac{s^2 - 2 s (m_1^2 + m_2^2) + {(m_1^2 - m_2^2)}^2}{4 m_2^2} \]

Parameters
p1pointer to particle 1
p2pointer to particle 2
Returns
the absolute value of the momentum of particle 1 in the lab frame, in MeV/c
