CREMA-Measuring the Ground State Hyperfine splitting of Muonic Hydrogen — •Siddharth Rajamohanan1, Ahmed Ouf1, and Randolf Pohl2 — 1Johannes gutenberg universität mainz, Mainz, Germany — 2PRISMA+Cluster of Excellence and Institute of Nuclear Physics, Johannes Gutenberg-Universitat Mainz, 55099 Mainz, Germany
Precision measurements on atoms and ions provide a wealth of information of bound state QED and is a unique test of the Standard Model. Significant work has been done to understand the proton radius puzzle. To this end, the CREMA collaboration is presently pursuing a pulsed laser spectroscopy measurement of ground state HFS in muonic hydrogen upto 1ppm accuracy to understand the Zemach radius, which encodes the magnetic properties of the proton. A unique laser system, the multi-pass cavity and the scintillation detection system are necessary for the experiment. We report our progress on the same.
