B mesons are a type of meson that contain a bottom quark (b quark) and an anti-quark. Mesons are subatomic particles made up of one quark and one antiquark, and they are part of the family of hadrons, which are particles affected by the strong force. B mesons come in several varieties, depending on the type of anti-quark they pair with the bottom quark.
