Axions produced in the early universe can form bound clumps of Bose Einstein condensates, which are in some cases well described by a classical field with a single dominant angular frequency, close to the axion mass. In the vicinity of external electromagnetic fields, these axion clumps will start to radiate energy due to the axion-photon coupling. We will here consider the electromagnetic...
I give an update on GAMBIT, the Global And Modular BSM Inference Tool. After briefly describing the main features of the GAMBIT code, I highlight why GAMBIT is a promising framework to isolate sign of physics beyond the standard models (BSM) of particle physics and cosmology. Then I show the latest GAMBIT results for a model where the gravitino, and the neutralinos and charginos are the only...
Confining hidden sectors at the GeV scale are well motivated by asymmetric
dark matter and naturalness considerations and can also give interesting collider signatures. Here we study such sectors connected to the Standard Model by a TeV scale mediator charged under both QCD and the dark force. Such a mediator admits a Yukawa
coupling between quarks and dark quarks which is generically...
