Strange Quark

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 (Ds), Sigma baryons (Σ), and other strange particles.
According to the IUPAP, the symbol s is the official name, while "strange" is to be considered only as a mnemonic. The name sideways has also been used because the s quark has an I3 value of 0 while the u ("up") and d ("down") quarks have values of +1/2 and −1/2 respectively.
Along with the charm quark, it is part of the second generation of matter. It has an electric charge of -1/3 e and a bare mass of 98±6 MeV/c2. Like all quarks, the strange 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 strange quark is the strange antiquark (sometimes called antistrange quark or simply antistrange), which differs from it only in that some of its properties have equal magnitude but opposite sign.
The strange quark contains a String.
==Strange antiquark==
The Anti-Strange Quark, Strange Antiquark or just Antistrange is the exact same thing as an Charm Quark, except the charge is negative, so the Anti-Strange Quark just has a charge of +1/3 e instead of -1/3 e.
A strange quark decays into an Up Quark and a W- Boson, which is short lived, and decays into an electron and an Electron antineutrino. An example of this decay is the decay of a Kaon minus (K-) particle. It lives about 10-8 seconds, which is ridiculously short. When it decays, it forms a π0 Pion (This is that particle that decays into an up quark). It also creates an electron and an Electron antineutrino.
