## Odderon

The Odderon effects remained elusive for a long time, due to lack of a deﬁnitive and statistically signiﬁcant experimen-tal evidence. A direct way to probe the Odderon in elastic scattering is by comparing the differential cross-section of particle– particle and particle–antiparticle scattering at sufﬁciently high energies [3,4].The TOTEM collaboration at the LHC, together with the DØ collaboration at the Tevatron collider at Fermilab, have announced the discovery of the odderon – an elusive state of three fundamental particles called gluons that was predicted almost 50 years ago. The result was presented on Friday 5 March during a meeting at CERN, and follows the joint submission in December 2020 of a CERN ...

In the 1950s, experimental data on the total cross-section for proton–proton collisions ( σpp) suggested that σpp was initially decreasing as the collision energy ... The Odderon was suggested 50 years ago [1, 2] as the C-odd (C= −1) partner of the C−even (C= +1) Pomeron in mediating a t-channel colorless exchange in elastic hadronic cross sections. The original idea [3] to measure the Odderon through a difference inppvs pp¯ elastic cross sections brought much excitement recently [4] thanks to theNature Reviews Physics - Elliot Leader recounts the theoretical prediction and recent discovery of the odderon.We describe the odderon as an effective vector exchange.

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.

EVOLVED T-ODD GLUON TMDSIn the saturation regime, the expectation value of odderon that incorporates multiple gluon exchange effect has been computed in the MV model [1] with a cubic term [27]. The energy dependence of the odderon exchange is described by the BKP equation [28], which also can be formulated in the dipole model [29] and CGC framework [30], [31].1.. Pomeron and Odderon exchanges are the theoretically dominant contributions to hadronic cross sections at high energy. They appear on an equal footing in the QCD description of hadronic reactions, and in the lowest order approximation they correspond to colour singlet exchanges in the t-channel with two and three gluons, respectively..
