  2. Antimatter - Wikipedia

    en.wikipedia.org/wiki/Antimatter

    Antimatter cannot be stored in a container made of ordinary matter because antimatter reacts with any matter it touches, annihilating itself and an equal amount of the container. Antimatter in the form of charged particles can be contained by a combination of electric and magnetic fields, in a device called a Penning trap .

  3. Annihilation - Wikipedia

    en.wikipedia.org/wiki/Annihilation

    Otherwise, the process is understood as the initial creation of a boson that is virtual, which immediately converts into a real particle + antiparticle pair. This is called an s-channel process. An example is the annihilation of an electron with a positron to produce a virtual photon, which converts into a muon and anti-muon.

  4. Creation and annihilation operators - Wikipedia

    en.wikipedia.org/wiki/Creation_and_annihilation...

    Creation and annihilation operators can act on states of various types of particles. For example, in quantum chemistry and many-body theory the creation and annihilation operators often act on electron states. They can also refer specifically to the ladder operators for the quantum harmonic oscillator. In the latter case, the creation operator ...

  5. Matter creation - Wikipedia

    en.wikipedia.org/wiki/Matter_creation

    The process inverse to particle annihilation can be called matter creation; more precisely, we are considering here the process obtained under time reversal of the annihilation process. This process is also known as pair production , and can be described as the conversion of light particles (i.e., photons) into one or more massive particles .

  6. Matter - Wikipedia

    en.wikipedia.org/wiki/Matter

    Antimatter is matter that is composed of the antiparticles of those that constitute ordinary matter. If a particle and its antiparticle come into contact with each other, the two annihilate; that is, they may both be converted into other particles with equal energy in accordance with Albert Einstein's equation E = mc 2.

  7. Elementary particle - Wikipedia

    en.wikipedia.org/wiki/Elementary_particle

    In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. [1] The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons .

  8. Feynman diagram - Wikipedia

    en.wikipedia.org/wiki/Feynman_diagram

    The normalization of the single-particle states must be chosen carefully, however, to ensure that M is a relativistic invariant. Non-relativistic single particle states are labeled by the momentum k, and they are chosen to have the same norm at every value of k. This is because the nonrelativistic unit operator on single particle states is:

  9. Antimatter weapon - Wikipedia

    en.wikipedia.org/wiki/Antimatter_weapon

    An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
