Pion-Nucleon Scattering in Lattice QCD |
Speaker: | Valentina Verduci (Uni Graz) |
Abstract: | We investigate the S-wave pion-nucleon scattering in lattice QCD, in order to obtain new information on the negative sector of the nucleon spectrum. This approach enables us to shed some light on the nucleon excited states and can be generalized to the study of other sectors of the QCD spectrum. |

Muonic Hydrogen and the Proton Radius Puzzle |
Speaker: | Randolf Pohl (Max-Planck-Institut für Quantenoptik) |
Abstract: | Muonic hydrogen is (μp) is the exotic hydrogen atom made from a proton and a negative muon μ-. Due to the large muon mass mμ ≈ 200me, the Bohr orbits are about 200 times smaller in mu- onic hydrogen, compared to regular hydrogen. This results in a 2003 ≈ 10^7 times larger overlap of the muon’s wave function with the proton, dramatically enhancing the sensitivity of μp energy levels to nuclear properties.
The finite size contribution to the Lamb shift in muonic hydrogen is as large as 2% of the total 2S Lamb shift.
This makes muonic hydrogen the ideal, clean, atomic system to study the proton rms charge radius.
We have recently measured two 2S-2P transitions in muonic hydrogen. From the Lamb shift we obtain a proton rms charge radius that is 10 times more accurate than the CODATA-2010 ... (full abstract is available here: https://www.smi.oeaw.ac.at/groups/hephysmiseminar/) |
