threshold
The dormant proton is bombarded with pawns. If the pawns bring enough energy into the system, then it is possible for it to be "spent" on creating new particles.
Calculate the threshold for the pion momentum so that the reaction π + p → K + bila is possible.
where the proton initially rests. The production threshold is the minimum energy required for the particles to form, that is, after the reaction, in the impulse center system,
the new particles are at rest (all the energy has gone to the creation of the particles, and not at all the energy
in their movement). For particle masses use mπc
2 = 150 MeV, mKc
2 = 500
MeV, mpc
2 = 900 MeV and mΣc
2 = 1200 MeV. Use a pulse center system.
• Write down 4 pulses of each of the particles in the LAB system, determine the total pulse
in the LAB system.
• p_mi p^mi
µ is a scalar to Lorentz transformations, which means that you can do this object
calculated in any system, the result will be the same in any other
Lorentz system
• 4-pulse is a conserved quantity
