The neutron Electric Dipole Moment (EDM) has attracted interest as a promising channel for finding new physics for a long time. The existence of a neutron EDM would violate CP symmetry given CPT conservation. This new source of CP violation could explain the baryon asymmetry of the universe. The BeamEDM experiment aims to measure the neutron EDM using a novel technique which overcomes the...
Despite the success of the Standard Model of particle physics long-standing open questions remain to be understood including the nature of dark matter, baryogenesis, and leptonic CP violation. Attention is being increasingly focused on the so-called intensity frontier at which small-scale experiments make high-precision measurements of a limited number of observables or search for rare or...
Ulrich Schmidt on behalf of the aSPECT collaboration
The aSPECT collaboration published in 2020 the most precise value on the electron-antineutrino correlation coefficient $a=-0.10407(82)$ of neutron $\beta$-decay. The value of this correlation coefficient $a$ is directly linked to the $\lambda$ parameter of the Weak Interaction of the Standard Model. The value for $\lambda$ obtained in...
Neutron interferometry [1], where an interference effects of matter waves passing through a perfect silicon-crystal interferometer is observed, has established a powerful tool for investigation of fundamental quantum mechanical concepts with massive particles [2]. In this talk I will give an overview of our recent work on weak measurements [3], a new type of quantum variable introduced by...
