Solving the Cosmic Lithium Problems with Gravitino Dark Matter in the CMSSM

Karsten Jedamzik, Ki-Young Choi, Leszek Roszkowski +1

Standard Big Bang nucleosynthesis at baryonic density as inferred by WMAP implies a primordial Li7 abundance factor of two to three larger than that inferred by observations of low…

An indirect dark matter search with diffuse gamma rays from the Galactic Centre with the Alpha Magnetic Spectrometer

A. Jacholkowska, G. Lamanna, E. Nuss +22

The detection of non-baryonic dark matter through its gamma-ray annihilation in the centre of our galaxy has been studied. The gamma fluxes according to different models have been…

Gravitino, Axino, Kaluza-Klein Graviton Warm and Mixed Dark Matter and Reionisation

Karsten Jedamzik, Martin Lemoine, Gilbert Moultaka

Stable particle dark matter may well originate during the decay of long-lived relic particles, as recently extensively examined in the cases of the axino, gravitino, and higher-dim…

Gravitino dark matter in gauge mediated supersymmetry breaking

Karsten Jedamzik, Martin Lemoine, Gilbert Moultaka

This paper investigates the parameter space of theories with gauge mediated supersymmetry breaking leading to gravitino (cold) dark matter with mass m_{3/2}= 1keV - 10MeV. We pay p…

Natural gravitino dark matter in SO(10) gauge mediated supersymmetry breaking

Martin Lemoine, Gilbert Moultaka, Karsten Jedamzik

It is shown that gravitinos with mass m_{3/2} ~ 0.1-1 MeV may provide suitable cold dark matter candidates in scenarios of gauge mediated supersymmetry breaking (GMSB) under SO(10)…
