Odderon
2.2.. Evolution equationIt is now straightforward to write down an evolution equation for the odderon in the dipole model. We have shown above that in the dipole model a single step of the small-x evolution for the odderon is the same as for the BFKL pomeron [19].Subsequent steps of the dipole evolution would generate more color dipoles in the onium wave function.Request PDF | On Jan 1, 2019, O.V.

Az Odderon létezését 1973-ban vetette fel először L. Lukaszuk és B. Niculescu. Az Odderon részecske felfedezésére, mérési adatokból történő biztonságos kimutatására azonban 2021-ig kellett várni.
