Accidentally Light Scalars from Large Representations: Inflation and Gravitational Waves
Speaker: Giacomo Ferrante (Montpellier University) Due to the infamous quadratic sensitivity of their masses to the UV scale, it is notoriously difficult to realise models where elementary scalar fields are light. Accidentally light scalars provide us with an interesting alternative to the wellknown cases of Nambu-Goldstone bosons (NGBs) and pseudo-NGBs. In models with spontaneous symmetry …
