Relic density of neutralinos in minimal supergravity
Howard Baer, Csaba Balazs, Alexander Belyaev
We evaluate the relic density of neutralinos in the minimal supergravity (mSUGRA) model. All 2->2 neutralino annihilation diagrams, as well as all initial states involving sleptons…
Are supersymmetric models with large tan(beta) natural ?
Howard Baer, Javier Ferrandis, Xerxes Tata
We point out that, contrary to general belief, generic supersymmetric models are not technically unnatural in the limit of very large values of the parameter tan(beta) when radiati…
Chargino Pair Production at One-loop
H. Baer, M. A. Diaz, M. A. Rivera +1
We use the quantum corrected chargino production cross section, including information on the beam polarization and chargino helicities, to estimate the precision achievable at a 1…
Radiative Neutralino Decay in Supersymmetric Models
Howard Baer, Tadas Krupovnickas
The radiative decay Z2-> Z1 gamma proceeds at the one-loop level in the MSSM. It can be the dominant decay mode for the second lightest neutralino Z2 in certain regions of paramete…
Neutralino relic density in minimal supergravity with co-annihilations
Howard Baer, Csaba Balazs, Alexander Belyaev
We evaluate the relic density of neutralinos in the minimal supergravity (mSUGRA) model. All 2-->2 neutralino annihilation diagrams, as well as all processes involving sleptons, ch…
