In science:

Without losing generality, we let the nucleon polarize along the third direction: J 3 QCD |psi = s |psi.
Gauge invariance and hadron structure
The expectation value of S + g on the |psi state is obviously also gauge invariant, since in our above proving of gauge invariance, the nucleon momentum is not constrained.
Gauge invariance and hadron structure
The calculation of the properties of hadronic atoms has received considerable attention over the last years, triggered mostly by the precise data from PSI for pionic hydrogen and deuterium and the DIRAC experiment (“pionium”).
Hadronic Physics
It is similar to the one applied for muonic helium some time ago. A main advantage is a slow-muon beam at PSI.
