The discovery of the pointlike constituents of the proton inspired massive experimental efforts to use deep inelastic scattering (DIS) to understand the partonic structure of hadrons. Early experiments were performed at fixed-target facilities, which made important findings but were limited in accessible kinematics. The Hadron-Electron Ring Accelerator (HERA), operated at DESY between...
The electro-weak part of Standard Model of Particle Physics predicts a neutron electric dipole moment (nEDM) of 10-32 e cm, far below current experimental sensitivities. Therefore, a non-vanishing nEDM by current experiments would be an unambiguous signature for new physics. Furthermore, any signal would indicate additional charge-parity violation beyond the Standard Model, giving new clues to...
Precision measurements in beta decay play an essential role in the search for new physics beyond the standard model (SM), by probing “exotic” phenomena such as scalar and tensor interactions. The presence of these interactions would lead to deviations in specific observables from their SM predictions. The study of the full beta energy spectrum offers a sensitive mean to probe these exotic...
Isospin-breaking corrections to the hadronic vacuum polarisation contribution to the muon g-2 are one of the largest contribution to the error in the latest lattice calculations. To reach the precision of the direct measurement of the muon anomalous magnetic moment, it is therefore crucial to reduce the uncertainties contributing to the total error of hadronic vacuum polarisation. I will...
