| Next-leading BFKL effects in forward-jet production at HERA |
| O. Kepka, C. Marquet, R. Peschanski, C. Royon |
We show that next-leading logarithmic (NLL) Balitsky-Fadin-Kuraev-Lipatov (BFKL) effects can be tested by the forward-jet cross sections recently measured at HERA. For $d\\sigma/dx,$ the NLL corrections are small which confirms the stability of the BFKL description. The triple differential cross section $d\\sigma/dxdk_T^2dQ^2$ is sensitive to NLL effects and opens the way for an experimental test of the full BFKL theoretical framework at NLL accuracy. |
