Is there a natural extension of the SM predicting a different mass for the anti-higgs to the higgs? Maybe also quantatively?!

This seemed very mysterious to me in the anonymous post on the Woit blog. It doesn't seem to be mentioned in the Strassler page or the Nature article. Isn't the Higgs supposed to be its own antiparticle? And I've never heard of an antiparticle having a different mass from the particle itself. In any case, it seems premature to talk about changing the standard model when there is actually no firm evidence that the Higgs has even been detected.

I got this link from the internet http://blog.vixra.org/2011/07/26/glo...tandard-model/

His conclusion is: In conclusion, the Standard Model is dead.

I'm not educated in QFT, but is what he says to come to that conclusion correct or is it more subtle than he makes it seem?

Thanks for the response to the anonymous post, which was the 22 July rumor referred to in the title. I was curious about it, suspicious a bit ---especially the part about antiHiggs detection at the different mass.
I get the sense that other people agree. It can be ignored. And nothing to confirm it has come in, I gather, during the past 4 days.

By "anti-Higgs", I think they mean a dip - an area with fewer events than expected. Not a particle.

Finally I get it!!!! Thanks Vanadium.

Now that 22 July rumor can be seen as roughly compatible with the more precise and reliable blog reports, from Strassler and others, we began to get at nearly the same time.

That second bump is at 250 GeV, not at 350 GeV, and though ATLAS sees it at almost 2 stdevs, CMS doesn't.

Extensions of the Standard Model like the Minimal Supersymmetric Standard Model (MSSM) predict more than one Higgs particle: three neutral ones and one charged one with charges +1 and -1.

So the ATLAS team could have detected two Higgs particles.

Let's not get ahead of ourselves. The ATLAS experiment hasn't said they see one, much less two!
