Fundamental physical constants: results in search for and description of variations
https://doi.org/10.32446/0368-1025it.2022-3-3-8
Abstract
We consider the current results in search for and description of temporal variations of fundamental physical constants (FPC) obtained under laboratory and astrophysical conditions. Results in search for constants variations have been obtained with the help of laboratory and astrophysical data. On the basis of fi xed values of base constants, those FPC have been chosen that can exhibit variations of greatest interest from the viewpoints of physics and metrology. An analysis of the current data concerning these constants is performed, and estimates of their variations on large time scales are presented. We point out the signifi cance of studying long-term FPC variations for both practical and fundamental metrology.
