Odderon

The odderon observation recently published by the D0 and TOTEM coll

It's an odderon, a particle that's even more odd than its name suggests, and it may have recently been detected at the Large Hadron Collider, the most powerful atom smasher, where particles are ...We study the perturbative Odderon in the quasidiffractive process γ (*) γ (*) →η c η c . At high energies this process is dominated by Odderon exchange and can be viewed as the theoretically cleanest test of the perturbative Odderon.

However, when combining this signal with the Odderon signals from the ReBB model in the 0.37 $\leq -t \leq$ 1.2 GeV$^2$ four-momentum-transfer range at $\sqrt{s} = $ 1.96, 2.76 and 7 TeV, it turns ..."The odderon is a solid prediction of the theory of strong interactions, made almost half a century ago," said physicist Yuri Kovchegov from The Ohio State University, who was not involved in the new work. "At the same time, it has been avoiding experimental detection for decades.

These findings are in agreement with recent experimental data, setting limits on the odderon contribution to the exclusive γp reactions. Integrable structures and duality in high-energy QCD.The use of pomeron/odderon trajectories in central exclusive production is outlined in Sec. 3. A simple analytic Regge trajectory is presented in Sec. 4. Single and double pole Regge fits to elastic scattering data are described in Sec. 5 and Sec. 6.

The implications of these data for Odderon (odd ... An alternative to probe the Odderon is the exclusive $\eta_c$ photoproduction in hadronic collisions. As the Pomeron exchange cannot contribute to this process, its observation would indicate the ...Jan 31, 2018 · Physicists have imagined the existence of the odderon for many decades, but until the LHC began operating at its highest energies in 2015, the odderon remained mere conjecture. The data collected and presented in the new paper was collected at 13 teraelectronvolts (TeV), the fastest scientists have ever been able to collide protons. In the first part of the talk, after going through a brief overview of the LHC and the physics, we will describe the odderon discovery by the TOTEM and D0 experiments. The analysis compares the p pbar elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured …

View.Un tipo particular de cuasipartícula se llama el odderon, predicho para existir en los años 70. Se cree que aparece cuando un número impar de quarks, partículas adolescentes que son los bloques de construcción de la materia, aparecen brevemente dentro y fuera de la existencia durante las colisiones de protones y antiprotones.Here we show that in the dual description the Odderon is the Reggeized Kalb-Ramond field (Bμν) in the Neveu-Schwartz sector of closed string theory. To first order in strong coupling, the high energy contribution of Odderon is evaluated for N = 4 Super Yang-Mills by a generalization of the gravity dual analysis for Pomeron in Ref. [1].

Abstract. 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. This calculation confirms the earlier finding that the spin ...We predict glueball/oddball resonances lying on the pomeron/odderon trajectories. A simple new form of the trajectories, with threshold and asymptotic behaviour required by analyticity and unitarity, is proposed. The parameters of these (pomeron and odderon) trajectories are fitted to the data on high-energy elastic proton-proton scattering. The fitted trajectories are extrapolated to the ...…
