M. B. Popovic (2012). "The Composite Particles Model (CPM), Vacuum Structure and ~ 125 GeV Higgs Mass," on hold at arXiv since May 14, 2012. [download PDF] Finally posted online at arXiv on June 8, 2012 hep-ph [1206.1507]
(CERN Press release) “Geneva 7 February 2012. The Standard Model Higgs search analyses presented at CERN by the ATLAS and CMS collaborations” suggest “that the Standard Model Higgs boson, if it exists, is most likely to have a mass constrained to the range 116-131 GeV by the ATLAS experiment, and 115-127 GeV by CMS. Tantalizing hints have been seen by both experiments in the region 124-126 GeV…”
(New York Times, July 5, 2012, Physicists Find Elusive Particle Seen as Key to Universe)"…The new particle has a mass of about 125.3 billion electron volts, as measured by the CMS group, and 126 billion according to Atlas. Both groups said that the likelihood that their signal was a result of a chance fluctuation was less than one chance in 3.5 million, “five sigma,” which is the gold standard in physics for a discovery….”
This paper explains why the ~125 GeV mass is as expected when Bose-Einstein statistics for kT~Mwc^2~80 GeV is applied to mixing of the two CMP predicted lowest mass states in 2D (113 GeV and 143 GeV) and same result is obtained for mixing in 4D (115 GeV and 346 GeV).
As can be easily verified, agreement between theoretical prediction and experimental result is rather excellent and hence unlikely by chance. Cite as: arXiv:1206.1507 [hep-ph] (or arXiv:1206.1507v1 [hep-ph] for this version)


M. B. Popovic (2011). "~115 GeV and ~143 GeV Higgs mass considerations within the Composite Particles Model," submitted to Physics Letters B on April 12, 2011; submitted to ArXiv.org hep-ph [1104.3111] on April 15, 2011, [download PDF]
Physicist at Fermilab's CDF experiment recently announced evidence of a peak (centered at 144 Gev) in a specific sample of its data (see announcement in The New York Times on April 5, 2011). This paper explains why the ~143.4 GeV mass is as expected.
Similarly, recent rumors in the physics blogosphere claim that ATLAS, one of the LHC’s all-purpose particle hunting experiments, caught a Higgs particle decaying into two high-energy photons at energy of 115 GeV (see post in Wired Magazine on April 21, 2011). This paper explains why the ~115.4 GeV mass is as expected.
Here is the latest version and comment on why I haven't published for a long time in particle physics journals.

Based on theoretical reasoning and a bit of intuition, in above paper I explain why I expect Higgs mass to be either ~115GeV or ~140GeV. Accidentally, folks at CERN observed a few suspicious events around 115GeV just before the LEP complex was shutdown in 2000 (when installation of the CERN's LHC began). Current (December 2007) experimental lower limit on the Higgs mass is still 114GeV.

Cern Press Release (September 2001):"...a number of events compatible with a Higgs boson production with mass around 114-115 GeV was reported in the combined results of the four LEP experiments, ALEPH, DELPHI, L3 and OPAL. However, the topology of these events is also compatible with originating from other known standard model processes. As a consequence, it is at present impossible either to rule out or confirm the existence of a 114-115 GeV Higgs boson..."

P. Renton "Has the Higgs boson been discovered?", Nature 428 (March 2004):"...There is some evidence (although statistically not very significant) for its detection at a mass of about 115 GeV/c2, from electron-positron interactions at LEP (the Large Electron Positron collider). Indirect methods can also be used to constrain the mass of the Higgs boson, because it affects other observable quantities (for example, the mass of the W boson and some measurable properties of the Z boson). An indirect determination of the Higgs boson mass from the most recent measurements of such quantities yields a value compatible with 115 GeV/c2, but with some important caveats arising from inconsistencies in the present data."
