Fragmentation of coloured strings in nuclear matter

Multidimensional study of hadronization in nuclei

“…The wealth of theoretical model calculations and studies [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] reflect the strong interest of the community in hadron-multiplicities on nuclei, as they provide information on the space (time) structure of the hadronization process. It is beyond the scope of this paper to compare the results of the various models with the data.…”

Hadron production in deep inelastic lepton–nucleus scattering

“…A modification of the string fragmentation mechanism to take this into account was proposed in Ref. [14]. Moreover, the differences at low z can be ascribed to target fragmentation protons, which can give a significant contribution to the multiplicity in this region.…”

“…(B.9). We obtain: Consider now the string fragmentation function of the Lund model [29]: 14) where p q is a probability that a given production point involves pair production of a particular flavor q, and C q are parameters controlling the typical momentum fraction carried by final hadrons containing that flavor:…”

“…Applications of the above mentioned nuclear absorption models to DIS on nuclear targets may be found in Refs. [14] and [15].…”

Study of the hadronization process in cold nuclear medium

“…In the above formula more variables like the photon virtuality-Q 2 , transverse hadron momentum in respect to the virtual photon direction-p t , over which the NA is averaged, are not written. At present, several phenomenological models for description of the NA [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] are available. The simple version of the string model, so called TwoScale Model (TSM), was proposed by European Muon Collaboration for the description of its experimental data [2].…”
