Konferensbidrag (refereegranskat)abstract
- The non-perturbative parton distributions in hadrons are derived. from simple physical arguments resulting in an analytical expression for the valence parton distributions. The sea partons arise mainly from pions in hadronic fluctuations. The model gives

A model for the parton distributions in hadrons

-
Tidskriftsartikel (refereegranskat)abstract
- A simple model is presented for the parton distributions in hadrons. The parton momenta in the hadron rest frame are derived from a spherically symmetric, Gaussian, distribution having a width motivated by the Heisenberg uncertainty relation applied to th

Tidskriftsartikel (refereegranskat)abstract
- Physics and programming aspects are discussed for a Fortran 77 Monte Carlo program to simulate complete events in deep inelastic lepton-nucleon scattering. The parton level interaction is based on the standard model electroweak cross sections, which are f

Tidskriftsartikel (refereegranskat)abstract
- The direct charmonium and bottomonium production rate observed at high p(perpendicular to) in p (p) over bar collisions at the Fermilab Tevatron is factors of 10 larger than predictions based on conventional perturbative QCD. We show that this excess can

Rapidity Gaps in DIS through Soft Colour Interactions

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- We present a new mechanism for the creation of large rapidity gaps in DIS events at HERA. Soft colour interactions between perturbatively produced partons and colour-charges in the proton remnant, modifies the colour structure for hadronization giving col

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The models for soft colour interactions and colour string re-interactions, implemented in the Monte Carlo program LEPTO, are investigated regarding hadronic final states in inclusive and diffractive deep inelastic scattering.

Soft colour interactions and the diffractive structure function

Ingår i: JOURNAL OF PHYSICS G-NUCLEAR AND PARTICLE PHYSICS. - : IOP PUBLISHING LTD. ; , s. 943-946
-
Konferensbidrag (refereegranskat)abstract
- We discuss our model for soft colour interactions and present results on the diffractive structure function F-2(D)(beta, x(P), Q(2)) and inclusive transverse energy flows, which agree with available HERA data.

Tidskriftsartikel (refereegranskat)abstract
- We introduce soft colour interactions as a novel mechanism to understand the observed events with large rapidity gaps in $ep$ collisions at HERA. Colour exchanges between produced partons and colour-charges in the proton remnant modifies the colour struct

Tidskriftsartikel (refereegranskat)abstract
- We show that the 'orthogonal' characteristics of the observed rapidity gaps and large forward energy flows in deep inelastic scattering at HERA, can be described within a single framework. Our Monte Carlo model is based on perturbative QCD matrix elements
