We propose a class of simple dark energy models which predict a late-time dark radiation component and a distinctive time-dependent equation of state $w(z)$ for redshift $z < 3$. The dark energy field can be coupled strongly enough to Standard Model particles to be detected in colliders, and the model requires only modest additional particle content and little or no fine-tuning other than a new energy scale of order milli-electron volts.
I love to hear about this stuff, but haven't a clue what you're talking about. That's ok, carry on. If it strikes a chord with you, maybe explain what's going on at Fermi D0.
ReplyDeleteVery strange news from D0. I would suggest we wait and see whether CDF (the competing detector collaboration at Fermilab) confirms their results.
