Torsion, Quantum Effects and the Problem of Cosmological Constant

Abstract

This symposium on the cosmological constant problem is being held concurrently with the workshop dealing with challenge in Tev physics. If one considers that the highest conceivable energy scale in either accelerator physics or cosmology is the Planck energy (ћc⁵/G)^1/2 ≃ 10¹⁹Gev = E_P1 and noting that the energy of the 2. 7° Kelvin cosmic microwave background photon is E _γ ≃ 10^–13Gev (in high energy parlance!) then we have the interesting coincidence (to be taken in lighter spirit!):

$$({E_{PL}} \times E\gamma ) \simeq oneTev!$$

Thus the Tev scale emerging as the geometric mean between the highest and lowest energy scales in big bang cosmology may serve as a unifying link connecting the two symposia on seemingly very different topics! After all the big bang was the biggest accelerator one could ever have had, but unfortunately now is in the deceleration phase with very low energy of 10^-13Gev! Of course we also have the postulated baryon number violation at Tev scales with its own profound cosmological consequences including relic Tev particles! Since this has been dealt with by other people we would not talk about this aspect any further in this article!
