As an unstable light pure leptonic system, positronium is a very specific probe atom to test bound state QED. In contrast to ordinary QED for free leptons, the bound state QED theory is not so well understood and bound state approaches deserve highly accurate tests. We present a brief overview of precision studies of positronium paying special attention to uncertainties of theory as well as comparison of theory and experiment. We also consider in detail advantages and disadvantages of… 
Lorentz violation in simple QED processes
We determine the effect of a CPT-even and Lorentz violating non-minimal coupling on the differential cross sections for some of the most important tree-level processes in QED, namely, Compton and
A status report on experimental tests of QED in medium-Z systems
Abstract The electron beam ion trap has opened the door for experimental physics to perform critical tests of bound state QED in the medium- Z regime. The relatively small uncertainties associated
Precision physics of simple atoms: QED tests, nuclear structure and fundamental constants
Abstract Quantum electrodynamics (QED) is the first successful and still the most successful quantum field theory. Simple atoms, being essentially QED systems, allow highly accurate theoretical
Positronium energy levels at order $m \alpha^7$: vacuum polarization corrections in the two-photon-annihilation channel
We have calculated all contributions to the energy levels of parapositronium at order $m \alpha^7$ coming from vacuum polarization corrections to processes involving virtual annihilation to two
Positronium portal into hidden sector: a new experiment to search for mirror dark matter
The understanding of the origin of dark matter has great importance for cosmology and particle physics. Several interesting extensions of the standard model dealing with solution of this problem
State-selective electric-field ionization of Rydberg positronium
We report experiments in which positronium (Ps) atoms, optically excited to Rydberg states with principal quantum numbers n in the range 18–25, were selectively ionized by both static and pulsed
2s Hyperfine splitting in light hydrogen-like atoms: Theory and experiment
Since the combination D21 = 8fHFS(2s)-fHFS(1s) of hyperfine intervals in hydrogen and light two-body hydrogen-like atomic systems weakly depends on the nuclear structure, comparison between theory
Testing QED and atomic-nuclear interactions with high-Z ions
Measurements of high-Z hydrogen-like ions have not yet been able to compete with the ultra-high precise test of quantum electrodynamics (QED) carried out using atomic hydrogen. However, recent
Testing QED in sodium-like gold and xenon: using atomic spectroscopy and an EBIT to probe the quantum vacuum
Electron Beam Ion Traps (EBITs) can strip atoms to their electronic cores, revealing strong perturbations of the quantum vacuum that occur at electric field strengths comparable to those in petawatt
Precision Microwave Spectroscopy of the Positronium n=2 Fine Structure.
A new measurement of the positronium (Ps) 2^{3}S_{1}→2^{3]P_{0} interval is reported, which is not in agreement with the theoretical value of ν_{0]=18498.25±0.61  MHz.


Precision study of positronium and precision tests of the bound state quantum electrodynamics
Despite its very short lifetime positronium provides us with a number of accurate tests of the bound state quantum electrodynamics (QED). In this note a brief overview of QED theory and precision
Experimental Tests of QED in Positronium: Recent Advances
The current experimental situation regarding tests of fundamental physics using positronium is reviewed. Five measurements are discussed and compared with theoretical predictions: the singlet and
Measurement of the decay e+e− → 4γ at rest
Abstract The decay of e+e− at rest into four photons has been measured in a 20-day experiment at the Heidelberg-Darmstadt Crystal Ball. From a total of 4.9 × 1010 annihilations observed, 406 4gg
Neutrino decay of positronium in the standard model and beyond
Whether in the Standard Model or beyond it, neutrinos contribute to the invisible decay mode of orthopositronium but practically not at all to that of parapositronium. Although this remark does not
Search for C-violating, P-conserving interactions and observation of 23S1 to 21P1 transitions in positronium
Possible C-forbidden transitions between 23S1 and 21P1 states of positronium are investigated. Limits are placed on the CP-violating state-mixing matrix element:|〈21P1|HHCP| 23P1〉| < 65MHz. Zeeman

A scheme for a precision measurement of the 1/ital S/-2/ital S/ transition frequency in positronium and muonium is reported, and corrections to the two most recent experiments are presented which
Muonium hyperfine structure and hadronic effects
A new result for the hadronic vacuum polarization correction to the muonium hyperfine splitting (HFS) is presented: Delta nu(had - vp) = (0.233 +- 0.003) kHz. Compared with previous calculations,
New precision measurement of the decay rate of singlet positronium.
The singlet decay rate has been measured using magnetic singlet-triplet state mixing for positronium formed in a [ital N][sub 2]-isobutane gas mixture and is the first measurement sensitive enough to test the relative order [alpha][sup 2]ln[alpha] term in the singlet Decay rate calculation.
