A Reevaluation of the Fundamental Physical Constants

Conference paper


This paper is a progress report on our current efforts to revise and update the comprehensive review of the fundamental physical constants by Taylor, Parker, and Langenberg (1), including their set of best or recommended values. That such an updating is necessary just two years after their review appeared is due to the extraordinary amount of new experimental and theoretical work which has since been completed. Here, we very briefly summarize the experimental and theoretical evidence, with emphasis on the new results which have become available within the last two years, and discuss various treatments of the data. However, no new set of recommended constants is given since such a set will necessarily require the inclusion of the new data which has become available at this Conference.

    Because the uncertainty in pi/p is 2.8 ppm, the two muonium alpha values cannot both be included since this 2.8 ppn uncertainty would be counted twice. Thus, we first combine via a weighted average the two values of v(Mhfs) and then obtain a single value of l/α(MHfs): 137.03631(22) (1.6 ppm). This approach will be used throughout as required.Google Scholar
