Oral talk

Particle dark matter, along with many ultraviolet scenarios, suggest
that additional low-energy degrees of freedom remain to be discovered.
Theories of new physics may be understood as data models, for which the
Lagrangian couplings are model parameters. The net worth of a theory is
determined by its Bayesian evidence: the likelihood of precision
cosmology data is multiplied by the prior...
