The linked dipole chain model for DIS

Hadronic final state predictions from CCFM: the hadron-level Monte Carlo generator Cascade

“…There exists also a third evolution equation, the Linked Dipole Chain (LDC) [ 22,23,24,25], whose characteristic is that some of the initial state radiation has been moved into the final state. This has two consequences -on one hand the simplifications that ensue mean that it is quite easy to correctly implement a symmetry between branching up and down in transverse scale (or equivalently one obtains the same predictions whether one evolves from the virtual photon or from the proton).…”

“…There are three equations which are commonly used for predictions in small-x DIS: the BFKL equation [ 19,20,21], the CCFM equation [ 10,11,12,13] and the LDC equation [ 22,23,24,25].…”

The BFKL equation at next-to-leading level and beyond

“…1) then reads 14) and contains only the shifted single poles in γ, while the neglected terms have no leading twist γ-singularities. This expression performs the resummation of the scale-dependent singularities proposed in ref.…”

“…[5], that χ ω 0 in eqs. (1.6) and (1.13) is provided by the eigenvalue function of the Lund model [14] …”

Forward π°-meson production at HERA

“…For the present analysis it was confirmed that the predictions depend strongly on the parameters controlling the "size" of the diquark and photon, and are therefore not explicitly compared with data in this paper 2 . The linked dipole chain (LDC) model [29] is a reformulation of the CCFM [30] equation, which forms a bridge between the BFKL and DGLAP approaches. Calculations of the hadronic final state based on this approach are available with the LDCMC 1.0 Monte Carlo which matches exact first order matrix elements with the LDC-prescribed initial and final state parton emissions.…”
