Fortunately, physicists developed the QCD factorization theorem, which separates the particle reaction processes.

Physicists have determined that in particle reactions, separate neutrino types are associated with three other types of lepton particles : electrons, muons and tau particles.
3.
Part of his dissertation derived procedures for stochastically simulating high-energy elementary particle reactions using digital computers, and Monte Carlo methodology would play a major role in his later work.
4.
The process has to occur in very high temperature environments ( above 10 9 kelvin ) so that the protons can overcome the large Coulomb barrier for charged particle reactions.
5.
In particle physics, charge conservation means that in elementary particle reactions that create charged particles, equal numbers of positive and negative particles are always created, keeping the net amount of charge unchanged.
6.
Reason : There is no article exactly suited to " Particle reaction ", but if you read all the way through the first paragraph of Chemical Reaction, you'll see that that category conceptually includes any particle transformation.
7.
A minor but often confusing point is as follows : most conserved quantum numbers are additive, so in an elementary particle reaction, the " sum " of the quantum numbers should be the same before and after the reaction.
8.
Since the energy of a thermal neutron is relatively low, charged particle reactions are discrete ( i . e ., essentially monoenergetic and lie within a narrow bandwidth of energies ) while other reactions such as gamma reactions will span a broad energy range, it is possible to discriminate among the sources.
