T mesons are hypothetical mesons composed of a top quark and either an up (
T0
), down (
T+
), strange (
T+
s
), charm antiquark (
T0
c
) or bottom antiquark (
T+
b
).[1] Because of the top quark's short lifetime, T mesons are not expected to be found in nature.[2] The combination of a top quark and top antiquark is not an open T meson, but rather a closed top-quark meson called toponium. Each T meson has an antiparticle that is composed of a top antiquark and an up (
T0
), down (
T
), strange (
T
s
), charm quark (
T0
c
) or bottom quark (
T
b
) respectively.
