2. Muon-induced background in a next-generation dark matter experiment based on liquid xenon

Vitaly Kudryavtsev

Session 1

Muon-induced neutrons can lead to potentially irreducible backgrounds in rare event search experiments. We have investigated the implication of laboratory depth on the muon induced background in a future dark matter experiment capable of reaching the so-called neutrino floor. Our simulation study focuses on a xenon-based detector with 70 tonnes of active mass, surrounded by additional veto...

7. When the Evaporation of Primordial Black Holes Messes Up with Dark Matter Production

Lucien Heurtier (IPPP, Durham, England)

05/05/2022, 11:10

Session 1

In this talk, I will present the phenomenology of dark-matter production in the case where it is both produced by thermal processes and by the evaporation of primordial black holes. I will show how the evaporation of primordial black holes may dramatically affect the production of dark-matter particles as well as its phase-space distribution. I will also show that the population of DM...

4. Design of a compact SiPM array for the Xenia detector

Andrew Stevens (Imperial College London)

05/05/2022, 11:30

Session 1

Liquid xenon time projection chambers (LXe-TPCs) have set leading limits on dark matter scattering over the past two decades. These have so far employed low-background photomultiplier tubes to detect the xenon VUV luminescence. With SiPMs now yielding competitive photon detection performance in the VUV, the possibility of using this technology in the next generation of experiments is becoming...

16. Intergalactic Dark Matter

Paul Frampton (University of Salento)

05/05/2022, 11:45

Session 1

We discuss PBHs as dark matter, including not only in galaxies and clusters of galaxies but extremely massive PBHs which may allow the total entropy to reach the maximum holographic value

3. FlameNEST: Explicit Profile Likelihoods with the Noble Element Simulation Technique

Robert James (UCL)

05/05/2022, 13:00

Session 1

We present FlameNEST, a framework providing explicit likelihood evaluations in noble element particle detectors using data-driven models from the Noble Element Simulation Technique. FlameNEST provides a way to perform statistical analyses on real data with no dependence on large, computationally expensive Monte Carlo simulations by evaluating the likelihood on an event-by-event basis using...

1. Searching for dilaton fields in the Ly$\alpha$ forest

Louis Hamaide

05/05/2022, 13:35

Session 1

Dilatons (and moduli) couple to the masses and coupling constants of ordinary matter, and these quantities are fixed by the local value of the dilaton field. If, in addition, the dilaton with mass $m_\phi$ contributes to the cosmic dark matter density, then such quantities oscillate in time at the dilaton Compton frequency. We show how these oscillations lead to broadening and shifting of the...

6. Quantum-enhanced interferometry for axion searches

Denis Martynov (University of Birmingham)

05/05/2022, 16:30

Session 1

We will discuss an experiment for searching axions and axion-like-particles in the galactic halo using quantum-enhanced interferometry. This setup will search for axions in the mass range from 10−16 eV up to 10−12 eV using an optical cavity. The sensitivity will be enhanced using squeezed states of light similar to the gravitational-wave detectors. The proposed experiment has the potential to...

14. QSNET project: A network of clocks for measuring the stability of fundamental constants

Leonid Prokhorov (University of Birmingham)

05/05/2022, 16:45

Session 1

The QSNET consortium is building a UK network of next-generation atomic and molecular clocks that will achieve unprecedented sensitivity in testing variations of the fine structure constant, alpha , and the electron-to-proton mass ratio, μ. In the range of parameters probed, either we will discover new physics, or we will impose new constraints on violations of fundamental symmetries and a...
