The 115 GeV ATLAS Higgs with enhanced diphoton decays has gone away but there are several other recent tantalizing hints relevant for particle physics, namely

and maybe others I missed. My question is simple:

Is there some sensible theoretical basis (e.g. paper) that would simultaneously explain at least two of the observations above if they were real?

Something I saw recently: arXiv 1104.4087 suggests a standard model compatible explanation for the CDF bump as an artifact of the selection criteria. –  dmckee May 9 '11 at 14:27
    
It's good but doesn't it explain just one of the bumps? –  Luboš Motl May 9 '11 at 14:30
    
Yes, it only addresses the possible $Z'$. –  dmckee May 9 '11 at 14:43
    
The electron dipole measurement motls.blogspot.com/2011/05/… seems like a strong negative hint, if it is as constraining as people say. –  Mitchell Porter May 30 '11 at 10:24
    
Couldn't ~100 GeV technipions and 800 GeV stable purely techincolor/QCD interacting technibaryons "explain" points 1 plus whichever other points? –  Ron Maimon Nov 16 '11 at 19:34

Funny two-step methods to link the observations, thanks, @Julius! ;-) A combination of a Z' interaction with dark matter is somewhat creative. –  Luboš Motl May 28 '11 at 4:21

My NEW preference is the scalar with charge +4/3 that is being postulated as an explanation for the top-antitop asymmetry.

There are some published papers pursuing this idea, such as http://arxiv.org/abs/1103.2757 or http://arxiv.org/abs/0912.0972 and a couple of mini reviews http://arxiv.org/abs/1108.3341 http://arxiv.org/abs/1107.0841.

As of today I can not tell which papers are the most relevant (see an explicit question in TP.stackexchange). I think that they have a potential to explain some of the other observations because the charge in some GUT models has a contribution from B-L and a contribution from SU(2) chiral groups, so the +4/3 is nor really so exotic.

In any case, take my answer with a bit of salt. As the uppercase acrostic indicates in the first paragraph, I also have some personal motivations to support models along this line, because I tripped into these pesky +4/3 things back in 2005 and I really want to understand how they fit.
