Hydrogen and muonic hydrogen atomic spectra in non-commutative space-time
M Haghighat, M Khorsandi - The European Physical Journal C, 2015 - Springer
Comparing electronic hydrogen with muonic hydrogen shows that the discrepancy in
measurement of the Lamb shift in the both systems are relatively of order of (m_ μ m_e)^ 4-5 …
