It’s our pleasure to inform you that the next SEENET-MTP online seminar will be
Some issues with gravitinos in high-scale supersymmetric models
Emilian Dudas (CNRS, Paris)
will be held Wednesday, 11 May 2022 at 17:00 CET.
Abstract: It has been recently realized that in some supergravity models of inflation and high-scale of supersymmetry breaking, gravitino propagation can become causal. Also, its sound speed could vanish leading to an unbounded growth in the production rate of gravitinos. I review and clarify the conditions for which this can happen. I will also comment on an infrared insight and ultraviolet origin of the potential acausality.
