Phys. Rev. E 64, 036125 (2001) [7 pages]Possible physical meaning of the Tsallis entropy parameterReceived 9 February 2001; published 30 August 2001 Since the proposal of the Tsallis generalized entropy, the general explanation of the role played by the parameter q that defines which specific entropy to pick among a whole family, remained somewhat partial and tentative, although some particular examples were taken into account specifically. The purpose of the present paper is to present a rigorous formal derivation of a mathematical expression giving the parameter q in terms of the momentum fluctuations of a stochastic process, thus furnishing at least one of its possible physical origins. © 2001 The American Physical Society URL:
