16. Double-beta decay and test of fundamental symmetries

Abstract
Double beta decay (DBD) is a currently hot research topic as it can offer a wide range of physics investigations beyond the Standard Model (BSM). These refer to some fundamental neutrino properties, yet unknown (neutrino nature – is it a Dirac or a Majorana...

19. The search for axion dark matter with a dielectric haloscope: MADMAX

Bela Majorovits (MPI for Physics), Bela Alexander Majorovits (Max Planck Society (DE))

Oral presentation

The QCD Axion is arguably the most elegant candidate to solve the strong CP problem and to explain missing dark matter in our universe. Some compelling theoretical models predict its mass to be around 100 μeV, a range that presently still evades experimental sensitivity. The dielectric haloscope concept has been proposed to change this. The motivation for post-inflationary dark matter axions...

23. LUXE: A new experiment to study non-perturbative QED in electron-LASER and photon-LASER collisions

Gianluca Sarri (Queen's University Belfast)

01/09/2022, 11:30

Oral presentation

The LUXE experiment (LASER Und XFEL Experiment) is a new large-scale experiment in planning at DESY Hamburg. LUXE is intended to study collisions between a high-intensity optical LASER and 16.5 GeV electrons from the XFEL electron beam, as well as collisions between the optical LASER and GeV-scale, high-flux photon beams. The main physics objective of LUXE is to experimentally study processes...

119. Origin of the Proton Mass

Craig Roberts (Nanjing University)

01/09/2022, 13:30

Oral presentation

Atomic nuclei lie at the core of everything we can see; and at the first level of approximation, their atomic weights are simply the sum of the masses of all the neutrons and protons (nucleons) they contain. Each nucleon has a mass mN ≈ 1 GeV, i.e. approximately 2000-times the electron mass. The Higgs boson - discovered at the large hadron collider in 2012 - produces the latter, but what...

40. Symmetry tests with clocks

Ekkehard Peik (Physikalisch-Technische Bundesanstalt, Braunschweig, Germany)

02/09/2022, 09:00

Oral presentation

We use frequency comparisons between highly accurate optical clocks for tests of fundamental principles. In particular, the 171Yb+ optical clock based on an electric octupole transition between the S-ground state and the lowest excited F-level (radiative lifetime 1.58 yr) provides a favorable combination of low systematic uncertainty and high sensitivity to relativistic effects and potential...
