The Case for an EeV Gravitino
Emilian Dudas, Yann Mambrini, Keith Olive
We consider the possibility that supersymmetry is broken above the inflationary mass scale and that the only "low" energy remnant of supersymmetry is the gravitino with mass of ord…
Phenomenological Constraints on Higgs reheating
Yann Cado, Mathieu Gross, Yann Mambrini +1
In many models of inflation, reheating is realized through a coupling between the inflaton and the Higgs boson. Often, the mass of the inflaton is of order GeV determined…
Phases in the MSSM, Electric Dipole Moments and Cosmological Dark Matter
Toby Falk, Keith Olive, Mark Srednicki
We consider the effect of CP violating phases in the MSSM on the relic density of the lightest supersymmetric particle (LSP). In particular, we find that the upper limits on the LS…
Supersymmetric Dark Matter in the Light of LEP 1.5
John Ellis, Toby Falk, Keith Olive +1
We discuss the lower limit on the mass of the neutralino that can be obtained by combining data from annihilation at LEP and elsewhere with astrophysical and theoreti…
A Systematic Study of the Stochastic Gravitational-Wave Background due to Stellar Core Collapse
Kyle Crocker, Tanner Prestegard, Vuk Mandic +3
Stellar core collapse events are expected to produce gravitational waves via several mechanisms, most of which are not yet fully understood due to the current limitations in the nu…
Constraining Supersymmetry
John Ellis, Keith Olive, Yudi Santoso
We review constraints on the minimal supersymmetric extension of the Standard Model (MSSM) coming from direct searches at accelerators such as LEP, indirect measurements such as b…
