What If Missing Particles and Stuff Cannot Be Found?

SpaceTiger is entirely correct. He is trying to be nice. I am not. Bad science is bad science and both of you guys should know better.

Sorry i have gone out of sync with the thread i lost connection to
PF while modifying post to Billy T.
The joys of the internet, can't live with it can't live without it seems
we all have problems from time to time Billy.

I guess it about time to let this thread slide into the archives, it has been
a revelation to me, and i thank every one who participated, i feel a little
let down that participation was not more diverse, but can understand the
constraints people work under.

Two new papers.

Title: Searches for the Higgs boson in Minimal Supersymmetric CP-conserving and CP-violating Standard Model scenarios at LEP
Authors: Pamela Ferrari
Comments: 4 pages, 4 figures

It is important to study extended models containing more than one physical Higgs boson in the spectrum. In particular, Two Higgs Doublet Models (2HDMs) are attractive extensions of the SM, predicting new phenomena with the fewest new parameters. The Higgs sector in the Minimal Supersymmetric extension of the SM (MSSM) is a 2HDM itself. The neutral Higgs searches performed at LEP are showing no evidence of the presence of a signal and have therefore been interpreted in the context of 2HDMs. Depending on the model considered exclusion of large regions of the parameter space can be obtained, but the existence of the lightest Higgs boson with masses lower than 90 GeV is not ruled out in all models by LEP. In the MSSM at least one of the neutral Higgs bosons is predicted to have its mass close to the electroweak energy scale; when radiative corrections are included, this mass should be less than about 140 GeV. This prediction provides a strong motivation for searches at present and future colliders.

Title: Results of a Search for Cold Flows of Dark Matter Axions
Authors: L. Duffy, P. Sikivie, D.B. Tanner, S. Asztalos, C. Hagmann, D. Kinion, L. J Rosenberg, K. van Bibber, D. Yu, R.F. Bradley
Comments: 5 pages, 3 figures

Theoretical arguments predict that the distribution of cold dark matter in spiral galaxies has peaks in velocity space associated with non-thermalized flows of dark matter particles. We searched for the corresponding peaks in the spectrum of microwave photons from axion to photon conversion in the cavity detector of dark matter axions. We found none and place limits on the density of any local flow of axions as a function of the flow velocity dispersion over the axion mass range 1.98 to 2.17 $\mu$eV.

This is a must read.

and this on Roger Penrose book The road to reality.

Seems i lied about letting this thread slip into the archives.

Hi, Wolram:

Here is a paper that might appeal to you. I have at this point only read portions of it (82 pages!), but it seems well-reasoned and well-presented.

Thanks Turbo.
