Comment on "What does the Letelier-Gal'tsov metric describe?"
G. Clement, D. V. Gal'tsov, P. S. Letelier
We show that the Letelier-Gal'tsov (LG) metric describing multiple crossed strings in relative motion does solve the Einstein equations, in spite of the discontinuity uncovered rec…
The Letelier-Gal'tsov spacetime revisited
G. Clement, D. V. Gal'tsov, P. S. Letelier
Contrary to a recent claim by Anderson ["The Mathematical Theory of Cosmic Strings", I.O.P. Publishing, Bristol 2003], we show that the Letelier-Gal'tsov metric does represent a sy…
Relic density of dark matter in mSUGRA and non-universal SUGRA
G. Belanger, F. Boudjema, A. Cottrant +2
The measurements of WMAP on the relic density of dark matter strongly constrain supersymmetric models. In mSUGRA where the neutralino LSP is mostly a bino only rather fine-tuned mo…
Uncertainties in the Prediction of the Relic Density of Supersymmetric Dark Matter
B. C. Allanach, G. Bélanger, F. Boudjema +1
We investigate how well the relic density of dark matter can be predicted in mSUGRA. We determine the parameters to which the relic density is most sensitive and quantify the colli…
Uncertainties in Relic Density Calculations in mSUGRA
B. C. Allanach, G. Belanger, F. Boudjema +2
We compare the relic density of neutralino dark matter within the minimal supergravity model (mSUGRA) using four different public codes for supersymmetric spectra evaluation. While…
