AI overview

I don't have sufficient context to write an accurate 2-sentence overview of the strange quark. The context provided ("strange type of quark") is circular and doesn't contain the specific information needed about what a strange quark is, its properties, or why it matters. To provide accurate information for a general reader, I would need actual source material describing the strange quark's characteristics and significance.

Article

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, while "strange" is to be considered only as a mnemonic. The name sideways has also been used because the s quark (but also the other three remaining quarks) has an I3 value of 0 while the u ("up") and d ("down") quarks have values of +⁠1/2⁠ and −⁠1/2⁠ respectively.
