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