Lubos mentions also second mysterious bump at 324.8 GeV or 325.0 GeV reported by CDF collaboration and discussed by Tommaso Dorigo towards the end of the last year. The decays of these particles produce 4 muons through the decays of two Z bosons to two muons. What is peculiar is that two mass values differing by .2 GeV are reported. The proposed explanation is in terms of Higgs decaying to two Z bosons. TGD based view about new physics suggests strongly that the three of four particles forming a multiplet is in question.
One can consider several explanations in TGD framework without forgetting that these bumps very probably disappear. Consider first the D0 anomaly alone.
- TGD predicts also higher generations but there is a nice argument based on conformal invariance and saying that higher particle families are heavy. What "heavy" means is not clear. It could of mean heavier that intermediate gauge boson mass scale. This explanation does not look convincing to me.
- Another interpretation would be in terms of scaled up variant of top quark. The mass of top is around 170 GeV and p-adic length scale hypothesis would predict that the mass should equal to a multiple of half octave of top quark mass. Single octave would give mass of 340 GeV. The deviation from predicted mass would be 5 per cent. This quark could correspond to t quark of scaled up hadron physics predicted by TGD and discussed in previous postings (see this, this, abd this).
If there indeed are two slightly different masses one can can ask whether the two different masses could be due to CP breaking. The mass difference between short-lived and long-lived ordinary kaon is however extremely small- 3.5×10-12 MeV- and scaling by a factor 512 would give quite too small mass difference. That CP (or even CPT) breaking should be so large for the scaled up version of hadron physics looks odd. As a matter fact, the splitting is of the same order as electromagnetic splitting between mesons with different charges obtained by scaling with factor 512 from the mass splitting of order 1 MeV for ordinary mesons.
Addition: The newest rumor is that ATLAS rumor about too photo-philic Higgs with exactly the same mass of 115 GeV as the hegemony wanted it to have was not more than a rumor. Sorry Lubos;-).
For me the newest rumor is a relief since it makes it more easier to find room for the remaining rumors in zoomed up hadron physics. The CDF rumor about 145 GeV bump would be interpreted in terms of charged pion. The latest D0 rumor weighting 325 GeV and producing W bosons, and the earlier CDF rumor having two slightly different masses around 325 GeV and producing two Z bosons would in turn be interpreted in terms of scaled up charged and neutral kaons.
However, if a strict scaling would hold true for the meson masses, one could conclude that either 145 GeV or 325 rumour is only a humor since the mass scale ratio 325/145 ≈ 2.24 is smaller than the mass scale ratio for ordinary kaon and pion about 490/140≈ 3.5. This would leave only one or two rumors to be killed. Probably they suffer a natural death within week or two in any case. I have not taken main stream theorists seriously for decades but believed that experimentalists are somehow more rooted in reality. Has the hype disease infected also experimentalists? This would be sad. Addition: The latest rumor about Atlas by Peter Woit tells that New Science has received inner information that ATLAS bump has not been found in other experiments. Tommaso in turn claims that this cannot be true! From which some reader concludes between lines that ATLAS has observed photo-philic Higgs after all!! When physics blogs came, I thought that they would provide forums for a genuine discussion about new ideas and could also serve some kind of educational function: for instance, about statistical methods of particle physics. I was wrong: they are forums for a chat about what names have said, for boosting the ego of the blogger, for the endlessly boring n sigma talk, and speculations around rumors and counter rumors. Does the situation in the web of so called respected blogs reflect the situation also in experimental particle physics? I sincerely hope that this is not the case.
