- We present a model based upon string dynamics for the small x and large k⊥ parts of the structure functions of a hadron. These ocean partons are taken as those available in the virtual string states, which are resolved by the field pulse q, in case the process is considered as a measuring process. The resulting distributions will for sufficiently small x (x⩽O(Q−4)) behave as 1/x in case we use the prescriptions of the Lund dipole model ([1,2]) and the soft radiation model ([3]).

Coherence Effects in Deep Inelastic Scattering
- 1989
-
Ingår i: Zeitschrift für Physik C Particles and Fields. - 0170-9739. ; 43:4, s. 625-632
-
Tidskriftsartikel (refereegranskat)abstract
- We present a framework for deep inelastic scattering, with bound state properties in accordance with a QCD force field acting like a vortex line in a colour superconducting vacuum, which implies some simple coherence effects. Within this scheme one may describe the results of present energies very well, but one obtains an appreciable depletion of gluon radiation in the HERA energy regime.

Gluon Splitting in the Color Dipole Cascades
- 1990
-
Ingår i: Nuclear Physics B. - 0550-3213. ; 339:2, s. 393-405
-
Tidskriftsartikel (refereegranskat)abstract
- We present a method to implement the gluon splitting process, g → QQ, into the dipole approximation to QCD cascades. It is known that due to the uncertainties in the interpolation between the pole regions, there are large uncertainties in the results. We show that there are further uncertainties due to the ordering in phase space of the gluon emission and gluon splitting processes. We present two options called the IO scheme (for independent dipoles) and another, the DO scheme (corresponding to an ordering in transverse momentum of the emissions) both of which lead to enhanced (hard) QQ-pair production, as compared to conventional cascades. We compare to present experimental data and give predictions for LEP energies.

The flavouring of a gluon jet
- 1990
-
Ingår i: Physics Letters B. - 0370-2693. ; 236:4, s. 461-465
-
Tidskriftsartikel (refereegranskat)abstract
- We show that the hard qq̄ production is very sensitive to the details of the parton shower and that our treatment based on the dipole approximation gives significantly larger production than “conventional” parton showers. For our model we find qualitative agreement with experimental data for the Kπ ratio and D-meson production in high-pT jets.

Tidskriftsartikel (refereegranskat)abstract
- The use of Object Oriented Programming languages and techniques for the development of Monte Carlo simulators for particle production and decay is discussed. For illustration, two specific "template" programs are presented written in Objective-C and in C++, respectively

A Phenomenological Investigation of the String Effect
- 1990
-
Ingår i: Physics Letters B. - 0370-2693. ; 241:1, s. 123-126
-
Tidskriftsartikel (refereegranskat)abstract
- We present results from Monte Carlo calculations of the string effect and the double inclusive correlation of particle flows for three-fold symmetric three-jet events in e+e− annihilation reactions at different energies. We find that the perturbative phase of the jet evolution quickly becomes dominant as energy increases.
