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

p1	pointer to particle 1
p2	pointer 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

p1	pointer to particle 1
p2	pointer to particle 2

Returns: the absolute value of the momentum of particle 1 in the lab frame, in MeV/c
