The antiproton, p, (pronounced p-bar) is the antiparticle of the proton.Antiprotons are stable, but they are typically short-lived, since any collision with a proton will cause both particles to be annihilated in a burst of energy.. The existence of the antiproton with electric charge of −1 e, opposite to the electric charge of +1 e of the proton, was predicted by Paul Dirac in his 1933 ...

In particle physics, every type of particle is associated with an antiparticle with the same mass but with opposite physical charges (such as electric charge).For example, the antiparticle of the electron is the positron (also known as an antielectron). While the electron has a negative electric charge, the positron has a positive electric charge, and is produced naturally in certain types of ...

Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation.The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are three generations of fermions, but ordinary matter is made only from the first fermion generation.

Pair production is the creation of a subatomic particle and its antiparticle from a neutral boson.Examples include creating an electron and a positron, a muon and an antimuon, or a proton and an antiproton.Pair production often refers specifically to a photon creating an electron–positron pair near a nucleus. As energy must be conserved, for pair production to …

En física, el protón (del griego πρῶτον, prōton 'primero') es una partícula subatómica con una carga eléctrica elemental positiva 1 (1,6 × 10-19 C), es igual en valor absoluto y de signo contrario a la del electrón, y una masa 1836 veces superior a la de un electrón.Su antipartícula, el antiprotón, tiene carga negativa -1.. Se ve el protón como estable, con un límite ...

In particle physics, annihilation is the process that occurs when a subatomic particle collides with its respective antiparticle to produce other particles, such as an electron colliding with a positron to produce two photons. The total energy and momentum of the initial pair are conserved in the process and distributed among a set of other particles in the final state.

Das Antiproton ist das Antimaterie-Teilchen (Antiteilchen) zum Proton.Es hat dieselbe Masse wie das Proton, aber negative Ladung. Antiprotonen sind Teil der kosmischen Strahlung.Auf der Erde kommen sie nicht natürlich vor und können nur künstlich in Teilchenbeschleunigern erzeugt werden; andere Antiteilchen, nämlich das Antineutrino und das Positron, entstehen hingegen …

An antimatter rocket is a proposed class of rockets that use antimatter as their power source. There are several designs that attempt to accomplish this goal. The advantage to this class of rocket is that a large fraction of the rest mass of a matter/antimatter mixture may be converted to energy, allowing antimatter rockets to have a far higher energy density and specific impulse …

The strange quark or s quark (from its symbol, s) is the third lightest of all quarks, a type of elementary particle.Strange quarks are found in subatomic particles called hadrons.Examples of hadrons containing strange quarks include kaons ( K), strange D mesons ( D s), Sigma baryons ( Σ), and other strange particles.. According to the IUPAP, the symbol s is the official name, …
