Positronium & Muonium: We1
- Ivan Logashenko (BINP)
Positronium is an excellent system to test bound state QED theory to very high precision, since it is almost exlusively governed by the electromagnetic force and does not exhibit the finite size effects which plague measurements of protonic atoms.
Numerous precise experiments have therefore been conducted in the past to measure the hyperfine splitting of Positronium. However, these...
Positronium spectroscopy is of continuing interest as a high-precision test of our understanding of binding in QFT. Positronium represents the purest example of binding in QFT as the constituents are structureless and their interactions are dominated by QED with only negligible contributions from strong and weak effects. Positronium differs from other Coulombic bound systems such as...
