Flat Tree-level Inflationary Potentials in Light of CMB and LSS Data
G. Ballesteros, J. A. Casas, J. R. Espinosa +2
We use cosmic microwave background and large scale structure data to test a broad and physically well-motivated class of inflationary models: those with flat tree-level potentials…
Determining Reheating Temperature at Colliders with Axino or Gravitino Dark Matter
Ki-Young Choi, Leszek Roszkowski, Roberto Ruiz de Austri
After a period of inflationary expansion, the Universe reheated and reached full thermal equilibrium at the reheating temperature T_R. In this work we point out that, in the contex…
On prospects for dark matter indirect detection in the Constrained MSSM
Leszek Roszkowski, Roberto Ruiz de Austri, Joe Silk +1
In the framework of the Constrained MSSM we derive the most probable ranges of the diffuse gamma radiation flux from the direction of the Galactic center and of the positron flux f…
Implications for the Constrained MSSM from a new prediction for b to s gamma
Leszek Roszkowski, Roberto Ruiz de Austri, Roberto Trotta
We re-examine the properties of the Constrained MSSM in light of updated constraints, paying particular attention to the impact of the recent substantial shift in the Standard Mode…
