Antimatter and Precision Measurements
Welcome to the homepage of the ERC project group STEP
Antiparticles are rarely found in nature – we observe them, e.g. in the nuclear beta-decay and in high energy cosmic rays, however they quickly annihilate in our world of matter. In contrast to our experience, the Standard Model of particle physics is symmetric regarding particles and antiparticles. The interest of my research is to compare conjugate particles and antiparticles in high-precision measurements to test this symmetry, and look for symmetry violation manifesting itself in different observations in particle antiparticle systems. To this end, I am interested in developing new antiparticle traps and measurement methods to improve the sensitivity of antiparticle precision measurements. Currently, we are developing a transportable antiproton trap to improve the high-precision charge-to-mass ratio comparison of the proton and the antiproton.
