Don't be fooled by the word "conformal". This is not "AdS/CFT" stuff. The math is not stringy. It is very largely the conventional standard model. They've found a way to extend it's applicability and make more radical changes unnecessary. Furthermore it's testable. Here's what Meissner and Nicolai said about the CSM in 2006(adsbygoogle = window.adsbygoogle || []).push({});

"...there exists a set of parameters for which the model may remain viable even up to the Planck scale. The decay modes of the extra scalar field provide a unique signature of this model which can be tested at LHC."

And here is what they said in 2012

A narrow scalar resonance at 325 GeV?

Krzysztof A. Meissner, Hermann Nicolai

(Submitted on 28 Aug 2012)

We propose to identify the excess of events with four charged leptons at E ~ 325 GeV seen by the CDF and CMS Collaborations with a new 'sterile' scalar particle characterized by a very narrow resonance of the same height and branching ratios as the Standard Model Higgs boson,as predicted in the framework of the so-called Conformal Standard Model

Nicolai gave what I thought was a very convincing presentation of the CSM at the 2009 Max Born conference in Wroclaw. Anyone interested in BtSM proposals who hasn't yet might want to watch the video.

As many of us know, Nicolai is a division head at Albert Einstein Institute (MPI-Golm) who directs the Unified Theories and Quantum Gravity program at AEI and is one of the foremost European string and field theorists. He has wisely supported both Loop and String research at AEI since before 2004 (like a scientist rather than a partisan), making the institute unique in Europe.

Good numbers.

Conformal Symmetry and the Standard Model

Krzysztof A. Meissner, Hermann Nicolai

(Submitted on 15 Dec 2006)

We re-examine the question of radiative symmetry breaking in the standard model in the presence of right-chiral neutrinos and a minimally enlarged scalar sector. We demonstrate that, with these extra ingredients, the hypothesis of classically unbroken conformal symmetry, besides naturally introducing and stabilizing a hierarchy, is compatible with all available data; in particular, there exists a set of parameters for which the model may remain viable even up to the Planck scale. The decay modes of the extra scalar field provide a unique signature of this model which can be tested at LHC.

...that is what they are talking about seeing signs of in the August 2012 paper.

Here are Nicolai's slides for the talk he gave about CSM at the 2009 conference ("On Planck Scale")

I don't have a working link to the video right now. It should be at http://www.ift.uni.wroc.pl/~planckscale/
