97. Feebly interacting particles: experimental prospects at accelerator-based experiments.

Gaia Lanfranchi (INFN)

04/06/2019, 09:00

Light and feebly interacting particles (axions/ALPs, HNLs, Dark Photons, Dark Scalars) represent an alternative paradigm to the current lore of New Physics at the TeV scale and are getting an increasing attention within the accelerator-based communities. I will review the experimental prospects for their searches at beam dump, fixed-target and collider-based experiments.

12. Observable signatures of dark photons from supernovae

Oral

A dark photon is a well-motivated new particle which, as a component of an associated dark sector, could explain dark matter. One strong limit on dark photons arises from excessive cooling of supernovae. We point out that even at couplings where too few dark photons are produced in supernovae to violate the cooling bound, they can be observed directly through their decays. Supernovae produce...

21. Status and prospects of the DarkSide project

Dr Xiang Xiao (UCLA)

04/06/2019, 09:55

Oral

DarkSide utilizes the 39Ar-depleted argon as target and the dual-phase Time Projection Chambers technology to search for WIMP signal. In this talk, I will review the recent results of the DarkSide-50 experiment, currently running at LNGS with 50-kg fiducial mass. I will also present the status of the DarkSide-20k experiment with 20-tonne fiducial mass. Plans for a further step towards a...

45. Searching for axion dark matter with tuneable plasma haloscopes

Dr Alexander Millar (Stockholm University)

Oral

We propose a new strategy to search for dark matter axions using tunable cryogenic plasmas. Unlike current experiments, which repair the mismatch between axion and photon masses via breaking translational invariance (cavity and dielectric haloscopes), a plasma haloscope enables resonant conversion by matching the axion mass to a plasma frequency. A key advantage is that the plasma frequency is...
