Low-scale gaugino mediation, lots of leptons at the LHC
Andrea De Simone, JiJi Fan, Martin Schmaltz +1
Low-scale gaugino mediation predicts that gauginos are significantly heavier than scalar superpartners. In order of increasing mass the lightest superpartners are the gravitino, ri…
Boltzmann brains and the scale-factor cutoff measure of the multiverse
Andrea De Simone, Alan H. Guth, Andrei Linde +3
To make predictions for an eternally inflating "multiverse", one must adopt a procedure for regulating its divergent spacetime volume. Recently, a new test of such spacetime measur…
Quantum Boltzmann equations in resonant leptogenesis
Andrea De Simone
The quantum Boltzmann equations relevant for leptogenesis, obtained using non-equilibrium quantum field theory, are described. They manifest memory effects leading to a time-depend…
Predicting the cosmological constant with the scale-factor cutoff measure
Andrea De Simone, Alan H. Guth, Michael P. Salem +1
It is well known that anthropic selection from a landscape with a flat prior distribution of cosmological constant Lambda gives a reasonable fit to observation. However, a realisti…
