Strange-quark

Key Stage 5

Meaning

A strange-quark (s) is a type of quark with a charge of \(-\frac{1}{3}\) and a strangeness of -1.

About Strange-quarks

The strange-quark is denoted with a lower case s.

The strange-quark decays via the weak interaction into a down-quark, losing it's strangeness.
