T mesons are hypothetical mesons composed of a top quark and one additional subatomic particle. The second subatomic particle can be either an up quark (
T0
), down quark (
T+
), strange quark (
T+
s), charm quark (
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.
