HIGHLIGHTS

• who: Luszczak Agnieszka from the Cracow University of Technology, Poland have published the article: Dipole model analysis of F2cc¯${rm{F}}_2^{{rm{cbar c}}} $ derived from the new D* data in DIS at HERA, in the Journal: (JOURNAL)

SUMMARY

In the dipole models: GBW and BGK the heavy quark contribution to F2 was considered in the form of the cc pair production. GBW (Golec-Biernat, Wüsthoff) parametrization: σ̂(r, x)=σ0 1 - exp(-r2 /Rs2 ), Rs2=4 · (x/x0 ) λ GeV 2. The dipole scattering amplitude in such a case reads: N̂ (r . . .
