Available energy (particle collision)

Available energy (particle collision)

In particle physics, the available energy is the energy in a particle collision available to produce new matter from the kinetic energy of the colliding particles. Since the conservation of momentum must be held, a system of two particles with a net momentum may not convert all their kinetic energy into mass - and thus the available energy is always less than or equal to the kinetic energy of the colliding particles. The available energy for a system of one stationary particle and one moving particle is defined as:: E_a = sqrt{2 m_t c^2 E_m + (m_t c^2)^2 + (m_k c^2)^2} where: m_t is the mass of the stationary target particle,: m_k is the mass of the moving particle,: E_m is the kinetic energy of the moving particle, and: c is the speed of light.
