Neutralino relic density including coannihilations

Paolo Gondolo, Joakim Edsjo

We give an overview of our precise calculation of the relic density of the lightest neutralino, in which we included relativistic Boltzmann averaging, subthreshold and resonant ann…

Rare decays of η-meson: the background of ρ- and ω- mesons

S. Kullander, H. Calén, K. Fransson +7

The problem of $ρ$ - and $ω$ - mesons contributions to the background for $η \to π^{0} e^{+} e^{-}$ decay and to the asymmetries in the decays $η \to π^{+} π^{-} π^{0}$ and $η \to π^{+} π^{-} γ$ is consider…

Report of the Working Group on Goldstone Boson Production and Decay

J. Bijnens, G. Colangelo, G. D'Ambrosio +11

This is the summary of the working group on Goldstone Boson Production and Decay of the Chiral Dynamics Workshop in Mainz, September 1-5, 1997. For the production aspects we discus…

Unified description of the non-singlet spin dependent structure function $g_{1}$ incorporating Altarelli-Parisi evolution and the double logarithmic $l n^{2} (1/ x)$ effects at low $x$

B. Badełek, J. Kwieciński

A unified equation for the non-singlet spin dependent structure function $g_{1}^{n s} (x, Q^{2})$ which incorporates the complete leading order Altarelli-Parisi evolution at finite $x$ an…

Neutralino Annihilation into a Photon and a Z boson

P. Ullio, L. Bergstrom

A full one-loop calculation of neutralino S-wave annihilation into the $Z γ$ final state is performed in the minimal supersymmetric extension of the Standard Model. This process, li…

On the Nature of the Magnetic Fields Generated During the Electroweak Phase Transition

Dario Grasso, Antonio Riotto

In this Letter we reanalyse the question of the origin of magnetic fields during the electroweak phase transition. We show that their formation is intimately connected to some semi…

Full One-loop Calculation of Neutralino Annihilation into Two Photons

L. Bergstrom, P. Ullio

For the first time, a full one-loop calculation of the process $χχ \to 2 γ$ is performed, where $χ$ is the lightest neutralino in the minimal supersymmetric extension of the Standard…

Quarkonium Production at the Tevatron through Soft Colour Interactions

A. Edin, G. Ingelman, J. Rathsman

The direct charmonium and bottomonium production rate observed at high-pt in pp-bar collisions at the Tevatron is factors of ten larger than predictions based on conventional pertu…

Aspects of Neutrino Detection of Neutralino Dark Matter

J. Edsjo

Neutralino dark matter, and in particular different aspects of its detection at neutrino telescopes, has been studied within the Minimal Supersymmetric extension of the Standard Mo…

Multiple inflation

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

Attempts at building an unified description of the strong, weak and electromagnetic interactions usually involve several stages of spontaneous symmetry breaking. We consider the ef…

Neutralino Relic Density including Coannihilations

J. Edsjo, P. Gondolo

We evaluate the relic density of the lightest neutralino, the lightest supersymmetric particle, in the Minimal Supersymmetric extension of the Standard Model (MSSM). For the first…
