Like your question. I've been stewing on this for 5 yrs now, but have gotten nowhere. Suggestions. For moral support on the CC, see Carlo Rovelli's great paper:http://arxiv.org/abs/1002.3966.
For physics(CC only, no dSS) see Beck: http://arxiv.org/abs/0810.0752
The electron & therefore QED must be involved. Dirac's 1935 paper was first to explore the relations of the electron in deSitter space. At first, it seems ridiculous: dS space is Defined tb devoid of particles & radiation ! However, there is a well defined area in GR w/its own metric, the Schwarzschild-deSitter metric. Combine that w/the infamous model of the Dirac electron as a Kerr-Newman BH & you see where this is going. If dS space can accommodate a BH, who cares if it's an electron !
So the idea is to do QED in dS space. The literature is Huge on QFT in dS space, but not much on QED/dS. Indeed, Planck's refined value of 3.3Gev/m^3 => a new target value for Lambda ~ 1.1E-52/m^2.
Do let me know if you have any ideas how to attack this problem.
The 'absence' of radiation & particles in dS space is of course a classical concept & I agree that Unruh & Hawking change the rules. Dirac's 1935 paper was the first, vis a vis the electron & dS space. It transforms the momentum-Dirac eq. over to an angular momentum eq. So is this quon thing your idea ?
I confess I've never heard of it. Refs? Anything beats SUSY, & I'm convinced she'll be history after the LHC 2015 run !
