The driving motivation for constructing the International Linear Collider is to produce the Higgs bosons (mass 125.09 GeV/c 2) in this way. The heaviest single-charged particle is the Z boson (mass 91.188 GeV/c 2). The heaviest particle pairs yet produced by electron–positron annihilation in particle accelerators are As a result, it becomes much easier to produce particles such as neutrinos that interact only weakly with other matter. Alternatively, it is possible to produce photons and other light particles, but they will emerge with higher kinetic energies.Īt energies near and beyond the mass of the carriers of the weak force, the W and Z bosons, the strength of the weak force becomes comparable to the electromagnetic force. If either the electron or positron, or both, have appreciable kinetic energies, other heavier particles can also be produced (such as D mesons or B mesons), since there is enough kinetic energy in the relative velocities to provide the rest energies of those particles. However, no other such particles are known. The same would be true for any other particles, which are as light, as long as they share at least one fundamental interaction with electrons and no conservation laws forbid it. The probability for such process is on the order of 10000 times less likely than the annihilation into photons.
Since neutrinos also have a smaller mass than electrons, it is also possible – but exceedingly unlikely – for the annihilation to produce one or more neutrino– antineutrino pairs. It is also possible to create any larger number of photons, but the probability becomes lower with each additional gamma photon because these more complex processes have lower probability amplitudes. It is also common for three to be created, since in some angular momentum states, this is necessary to conserve charge parity. You’re much more likely to resolve a conflict through gunplay here than by using stealth or demolitions it sets the game apart from the likes of Desperados 3 even more, even though it’s still satisfying to toss a. A convenient frame of reference is that in which the system has no net linear momentum before the annihilation thus, after collision, the gamma photons are emitted in opposite directions. We enjoyed that Hard West 2 favors traditional turn-based mechanics over the more role-based gameplay we saw in Desperados 2.
) In the most common case, two gamma photons are created, each with energy equal to the rest energy of the electron or positron ( 0.511 MeV). (An exception to this rule can occur for tightly bound atomic electrons. Conservation of energy and linear momentum forbid the creation of only one photon. The most probable is the creation of two or more gamma photons. There are only a very limited set of possibilities for the final state. net) lepton number, which is the number of leptons (such as the electron) minus the number of antileptons (such as the positron) this can be described as a conservation of (net) matter law.Īs with any two charged objects, electrons and positrons may also interact with each other without annihilating, in general by elastic scattering. However, in quantum field theory this process is allowed see examples of annihilation. This forbids the creation of a single photon.
