UCMN International Research Project

From the Hot Universe to Dark Matter

Participants (FR) : CNRS, Ecole Polytechnique et Université Paris-Saclay

Participants (US) : University of Minnesota

he UCMN IRP project is based on existing 25-year collaborations between groups in Minneapolis and Paris, and will focus on the following areas:

  • Analyze the non-perturbative effects generated by the exchange of gravitons, or non-minimal couplings to the Ricci scalar, on dark matter production and the reheating process as a whole;
  • Calculate the spectrum of gravitational waves generated by the scattering of inflation during this early phase, to check whether they can be observed by LISA or the future Einstein telescope;
  • Continue work on on high-scale supersymmetry and supergravity;
  • Evaluate the mechanisms of gravitational production and relate them to a microscopic field theory.

The expertise in cosmology, astrophysics and holographic models for physics beyond the Standard Model of the Minnesota participants will greatly contribute to the success of the collaboration and to the training of French thesis students.
