About the Orthopositronium Decay Rate and Analysis of Some O ( Α 2 ) Contributions
نویسنده
چکیده
I consider the problem of the evaluation of the orthopositronium decay rate, including second order radiative corrections. I present a brief theoretical discussion of this problem and a review of the results available in literature, and, then, I analyze some O(α 2) annihilation-type contributions, recently computed.

Virtual annihilation contribution to orthopositronium decay rate
Positronium, the bound state of an electron and positron, is an excellent laboratory to test our understanding of Quantum Electrodynamics of bound states. Although in the majority of cases the agreement between theory and experiment is very good, the case of orthopositronium (o-Ps) decay into three photons is outstanding, since the theoretical predictions differ by about 6 standard deviations f...
متن کاملOrder α 2 corrections to the decay rate of orthopositronium
Order α 2 corrections to the decay rate of orthopositronium are calculated in the framework of nonrelativistic QED. The resulting contribution is found to be in significant disagreement with one set of experimental measurements, though another experiment is in agreement with theory. The discrepancy between theory and experiment for the decay rate of orthopositronium has long been one of the out...

متن کاملPrecision Measurement of Orthopositronium Decay Rate Using SiO2 Powder
The intrinsic decay rate of orthopositronium formed in SiO2 powder is measured using the direct 2γ correction method such that the time dependence of the pick-off annihilation rate is precisely determined using high energy-resolution germanium detectors. As a systematic test, two different types of SiO2 powder are used with consistent findings. The intrinsic decay rate of orthopositronium is fo...
