On the four-dimensional conformal anomaly, fractal Cantorian space-time and the fine structure constant

Abstract:

Antoniadis, Mazur and Mottola (AMM) two years ago computed the intrinsic Hausdorff dimension of space-time at the infrared fixed point of the quantum conformal factor in four-dimensional gravity. The fractal dimension was determined by the coefficient of the Gauss-Bonnet topological term associated with the conformal gravitational anomaly and was found to be greater than 4. It is explicitly shown how one can relate the value of the Hausdorff dimension computed by AMM to the universal dimensional fluctuation of space-time ε given by φ3/2, where φ is the golden mean 0.618... Based on the infrared scaling limit of the theory and using recent renormalization group arguments by El Naschie, we conjecture that the unknown coefficient Q2, associated with the four-dimensional gravitational conformal anomaly, could be precisely equal to the inverse fine structure constant values ranging between 137.036 and 137.641. Our results generate decimal digits up to any arbitrary number an d are very close to El Naschie's exact E(∞) value ᾱ0=137.082039325. © Elsevier Science Ltd. All rights reserved.
