MSSM Higgses as the source of reheating and all matter
Kari Enqvist, Shinta Kasuya, Anupam Mazumdar
We consider the possibility that the dark energy responsible for inflation is deposited into extra dimensions outside of our observable universe. Reheating and all matter can then…
Challenges in generating density perturbations from a fluctuating inflaton coupling
Kari Enqvist, Anupam Mazumdar, Marieke Postma
We discuss the possibility of generating adiabatic density perturbations from spatial fluctuations in the inflaton decay rate which are due to quantum fluctuations of light moduli…
Q-ball dynamics from atomic Bose-Einstein condensates
K. Enqvist, M. Laine
Relativistic scalar field theories with a conserved global charge Q possess often (meta)stable spherically symmetric soliton solutions, called Q-balls. We elaborate on the perfect…
MSSM flat direction as a curvaton
Kari Enqvist, Asko Jokinen, Shinta Kasuya +1
We study in detail the possibility that the flat directions of the Minimal Supersymmetric Standard Model (MSSM) could act as a curvaton and generate the observed adiabatic density…
