Systematic effects in the determination of the piNN Coupling from pbar p -> nbar n differential cross section

T. E. O. Ericson, B. Loiseau

We show that the coupling constant extracted model-independently from charge exchange is subject to a systematic correction, and, more importantly, that the strong…

Measurement of the proton and deuteron structure functions, F2p and F2d, and of the ratio sigma(L)/sigma(T)

The New Muon Collaboration

The muon-proton and muon-deuteron inclusive deep inelastic scattering cross sections were measured in the kinematic range 0.002 < x < 0.60 and 0.5 < Q2 < 75 GeV2 at incident muon e…

Natural Supergravity inflation

Jennifer A. Adams, Graham G. Ross, Subir Sarkar

We identify a new mechanism in supergravity theories which leads to successful inflation without any need for fine tuning. The simplest model yields a spectrum of density fluctuati…

Indirect Neutralino Detection Rates in Neutrino Telescopes

L. Bergstrom, J. Edsjo, P. Gondolo

Neutralinos annihilating in the center of the Sun or the Earth may give rise to a detectable signal of neutrinos. We derive the indirect detection rates for neutrino telescopes in…

Properties of HERA Events from DIS on Pions in the Proton

M. Przybycien, A. Szczurek, G. Ingelman

Recently the concept of the pion cloud in the nucleon turned out to be successful in understanding the Gottfried sum rule violation observed by the New Muon Collaboration and the D…

Fixing the renormalisation scheme in NNLO perturbative QCD using conformal limit arguments

J. Rathsman

We discuss how the renormalisation scheme ambiguities in QCD can be fixed, when two observables are related, by requiring the coefficients in the perturbative expansion relating th…

MAJOR 1.5 - A Monte Carlo Generator for Heavy Majorana Neutrinos in Collisions

J. Rathsman, G. Ingelman

The Monte Carlo generator {\sc Major} 1.5 simulates the production and decay of heavy Majorana neutrinos via lepton mixing or exchange of `light' right-handed -bosons in deep in…

LEPTO 6.5 - A Monte Carlo Generator for Deep Inelastic Lepton-Nucleon Scattering

G. Ingelman, A. Edin, J. Rathsman

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 interac…

AROMA 2.2 - A Monte Carlo Generator for Heavy Flavour Events in Collisions

G. Ingelman, J. Rathsman, G. A. Schuler

A program to simulate the production of heavy quarks through the boson-gluon fusion process in collisions is presented. The full electro\-weak structure of the electron-…

Unified Description of Rapidity Gaps and Energy Flows in DIS Final States

A. Edin, G. Ingelman, J. Rathsman

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 fr…

Neutrino Dispersion in Magnetized Media and Spin Oscillations in the Early Universe

Per Elmfors, Dario Grasso, Georg Raffelt

We derive general expressions for the neutrino dispersion relation in a magnetized plasma with a wide range of temperatures, chemical potentials, and magnetic field strengths. If t…

Searching for Heavy Quarks at NMC: A Simple Estimate of Background Muons from and decays

M. Thunman

New physics can be searched for in deep inelastic scattering experiments. New phenomena, like additional production mechanisms for heavy quarks, manifest themselves through product…

Signals for Intrinsic Charm in High Energy Interactions

G. Ingelman, M. Thunman

The prospects to test the hypothesis of intrinsic charm quarks in the proton are investigated. We consider how this component can be directly or indirectly probed in deep inelastic…

High Energy Neutrino Production by Cosmic Ray Interactions in the Sun

G. Ingelman, M. Thunman

The flux of neutrinos originating from cosmic ray interactions with matter in the Sun has been calculated based on Monte Carlo models for high energy particle interactions. The res…

Atmospheric muons and neutrinos from charm

P. Gondolo, G. Ingelman, M. Thunman

We have updated our previous investigation of the production of muons and neutrinos in cosmic ray interactions with the atmosphere, taking account of recent results from the c…

Soft Colour Interactions and the Diffractive Structure Function

A. Edin, G. Ingelman, J. Rathsman

We discuss our model for soft colour interactions and present results on the diffractive structure function $F_2^D(β,x_\pom,Q^2)$ and inclusive transverse energy flows, which agree…
