Calculation of the Dirac hydrogen atom spectrum in the framework of dynamical fine structure constant (alpha) variability discloses a small departure in the laboratory from Sommerfeld's formula for the fine structure shifts, possibly measurable today. And for a distant object in the universe, the ...
This technique enables the measurement of known quantum effects such as the fine structure and the Lamb shift, which have now been measured in the antihydrogen atom for the first time. The ALPHA team previously used this approach to measure other quantum effects in antihydrogen, the most ...
There is an error induced by the uncertainty in α(M2Z), the fine structure constant of QED, arising from the contribution of light quarks. 2. The theoretical error on αS(M2Z), the QCD running coupling constant, comes from missing higher order electroweak corrections and uncertainties in th...

Monolith orhoneycomb structureis the dominant catalyst support for automobile exhaust conversion. Cordierite containing twoMgO, five SiO2, and two Al2O3parts is the preferred material composition.Ceramic honeycombssupporting Pt/Rh/Pd NPs are effective in the case of gasoline engines operating at a sto...
ACCORDING to the Dirac theory of the energy states in hydrogen-like spectra, levels of the same principal quantum number n which have the same value of the quantum number of total angular momentum j should coincide. Lamb and Retherfordhave shown that in the second quantum state of the ...
Thus, the crosslinked resin becomes processable, even though the crosslinked structure is not removed. Such resins are known as covalent adaptable networks (CANs)78,79. CANs, whose crosslinked structure is reformed via bond exchange by an addition–elimination mechanism (associative bond exchange), ...
