Charm Quark

The charm quark, charmed quark or c quark (from its symbol, c) is the third-most massive of all quarks, a type of elementary particle. Charm quarks are found in hadrons, which are subatomic particles made of quarks. Examples of hadrons containing charm quarks include the J/ψ meson (J/ψ), D mesons (D), charmed Sigma baryons (Σc), and other charmed particles.
It, along with the strange quark, is part of the second generation of matter, and has an electric charge of +2/3 e and a bare mass of 1.275±0.03 GeV/c2.
Like all quarks, the charm quark is an elementary fermion with spin 1/2, and experiences all four fundamental interactions: gravitation, electromagnetism, weak interactions, and strong interactions. The antiparticle of the charm quark is the charm antiquark (sometimes called anticharm quark or simply anticharm), which differs from it only in that some of its properties have equal magnitude but opposite sign.
The charm quark contains a String.
==Charm antiquark==
The Anti-Charm Quark, Charm Antiquark or just Anticharm is the exact same thing as an Charm Quark, except the charge is negative, so the Anti-Down Quark just has a charge of -2/3 e instead of +2/3 e.
A charm quark decays into an Strange Quark and a W+ Boson, which is short lived, and decays into an positron and an Electron neutrino. An example of this decay is the decay of a D+ particle. It lives only 10-12 seconds! When it decays, it forms a K- Kaon (This is that particle that decays into a strange quark). It also creates a π0, π+, a positron and an Electron neutrino. The charm quark also has a 5% chance to decay into a Down Quark instead.
