The available process types are:

• 0: No previous process yet, particle was created at initialization
• 1: Elastic scattering
• 2: Resonance formation (2 -> 1)
• 3: Inelastic binary scattering (2 -> 2)
• 5: Resonance decay
• 6: Box wall crossing (due to periodic boundary conditions)
• 7: Forced thermalization
• 8: Hypersurface crossing
• 9: Bremsstrahlung
• 41: Soft string excitation, single diffractive AB -> AX
• 42: Soft string excitation, single diffractive AB -> XB
• 43: Soft string excitation, double diffractive
• 44: Soft string N-Nbar annihilation
• 45: Soft sring excitation, non-diffractive
• 46: Hard string excitation
• 47: Failed string process
