It was first introduced in 1973 on the theoretical basis of asymptotic theorems [4]. The name "Odderon" itself was introduced two years later [5].

Discover the world's research. 25+ million members; 160+ million publication pages;Through painstaking work, scientists have found evidence of a quasiparticle that was first imagined as a hypothesis almost 50 years ago: the odderon.. The odderon is a combination of subatomic particles rather than a new fundamental particle - but it does act like the latter in some respects, and the way it fits into the fundamental building blocks of matter makes the discovery a huge moment ...The most reasonable appropriate hadron state in the Odderon channel is the ω meson. Therefore the growth of the Odderon radius with energy is expected to be less than the growth of the black disk radius driven by the even-signature amplitude, and the whole Odderon contribution will be ‘absorbed’ (i.e. power of s suppressed) by the black …F roissaron and Maximal Odderon model describ es per- fectly all the forward scattering TOTEM data [18-20], including the surprisingly small value of the ratio ρ atmodel that has Odderon amplitude.

In this short note, we report a di-quark model calculation for the spin dependent odderon and demonstrate that the asymmetrical color source distribution in the transverse plane of a transversely polarized hadron plays an essential role in yielding the spin dependent odderon.
