Discussion Overview

The discussion revolves around the recent discovery of a dijet peak in the 120 GeV to 160 GeV mass region at the Tevatron, with some participants suggesting it may be indicative of the Higgs boson, while others express skepticism regarding its significance and implications for the standard model of particle physics.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant proposes that the dijet peak could represent a Higgs boson, suggesting that it decays into a bound state of six top quarks and six anti-top quarks, which may be lighter than half the Higgs mass.
  • Another participant references Holger Nielsen's controversial theories, including a claim that the LHC could be destroyed by a time-traveling attack, which raises questions about the credibility of some interpretations of the data.
  • A participant shares a comment from Tommaso Dorigo, who is associated with the CDF collaboration, indicating skepticism about the bump being a Higgs or anything significant at all.
  • Further commentary from Dorigo suggests that Nielsen's ideas may be irrelevant and highlights a history of speculative claims that have not been substantiated.
  • One participant notes that such bumps in data can often be noise, yet expresses hope that the persistent reports may indicate a significant finding.
  • Another participant expresses frustration with the elusive nature of the Higgs boson, speculating on the potential for new theories to emerge that could alter the standard model.
  • A participant reminds others that the D0 experiment at Fermilab did not reproduce the CDF bump, suggesting caution in interpreting the results.

Areas of Agreement / Disagreement

Participants exhibit a range of views, with some supporting the idea that the dijet peak could be related to the Higgs boson, while others express skepticism and highlight the lack of reproducibility in experimental results. The discussion remains unresolved, with multiple competing interpretations present.

Contextual Notes

There are limitations regarding the assumptions made about the significance of the dijet peak, the dependence on interpretations of experimental data, and the unresolved nature of the claims surrounding the Higgs boson and related theories.

Abstract
"The newly found \cite{CDFnew} dijet peak in the 120 GeV to 160 GeV mass region produced in co-production with W IS actually a Higgs Boson in spite of the expectation of a different decay pattern for most Higgses. Our point, however, is that the bound state of 6t + 6$\bar{t}$, which we have put forward already in several articles \cite{boundfirst}\cite{bound} \cite{dark}\cite{hierarchybound}, easily could be lighter - possibly much lighter - than half the Higgs mass. Higgs would in this case decay dominantly to two of our bound states. If these bound states were indeed very light (say around 10 GeV) their decay products into hadrons would like two jets, one for each bound state. Even a very small mass for our bound state is not unexpected isofar as it is part of our model that especially the top-quark-Yukawa coupling is being tuned so as to make precisely this bound state of $6t + 6\bar{t}$ become (approximately) massless. This tuning is a consequence of our Multiple Point Principle \cite{old} \cite{SIMPP} which states that the realized parameter/coupling values correspond to having a maximal set of degenerate vacua. Even the very recent LHC-peak in photon photon might be fitted to our model."

Any thoughts? :)

erm, Holger Nielsen, formerly respected "originator of string theory" (one of) , well known for this:

http://www.nbi.dk/~kleppe/random/a1/aa.html

and the LHC is going to be destroyed by a backwards in time attack or something crazy like that (apologies to Beyonce)
 
Here is the article by the CDF collaboration "Invariant Mass..." that Nielsen refers to:

Here is Tommaso Dorigo's blog comment. He belongs to the CDF himself. I think he is saying he bump is not a Higgs and may not be anything at all:

Here is the Not Even Wrong post, which has links to other blogging about it:

One of the N.E.W. comments is by Dorigo.

Here are 18 links to blogs about it that arxiv provides:

More directly to the point. Here is Tommaso's (brief) comment on the Holger Nielsen paper you mentioned:

Nielsen On The CDF Bump

Worth mentioning because of its irrelevance: that's my other choice for a post which points out a new preprint by H.Nielsen, the Danish physicist who became famous by hypothesizing that the future was influencing the past in order to prevent us from discovering the Higgs boson.
[ http://arxiv.org/abs/0707.1919 ]
When I read back the piece I wrote back then ("Respectable physicists gone crackpotty") I cannot stop chuckling -I think it is one of my best posts ever. So I cannot even think of sitting down to write a similar one on the new work by Nielsen. You will have to find out by yourself to what heights the vagaries of the fellow have gotten.

Often times these bumps are noise in the background, but we have been seeing these news for a while now so maybe we are close to something. Otherwise if it is as Nelson states, then we'll never be able to find the Higgs.
 
Curse you, Higgs! I'm sure given enough time and energy (LHC cranked up to 7TeV) we'll be able to spot it. Unless, someone comes up with a theory that completely changes the standard model.. which is more likely? Guess we'll just have to find out.
