Phys. Rev. D 65, 083001 (2002) [5 pages]Quintessence and variation of the fine structure constant in the cosmic microwave background radiationReceived 25 October 2001; published 8 March 2002 We study the dependence of the CMB temperature anisotropy spectrum on the value of the fine structure constant α and the equation of state of the dark energy component of the total density of the universe. We find that bounds imposed on the variation of α from the analysis of currently available CMB data sets can be significantly relaxed if one also allows for a change in the equation of state. © 2002 The American Physical Society URL:
