Eventually, The Tevatron Also Sees The Higgs!

I think I wrote a post about the "definitive results" of the CDF and DZERO experiments on the search for the Higgs boson at least a couple of times already in the past, but you know, these busy experimentalists continue to improve their analyses, ...

Rescinded: The Light Matter Proposal: The Effect of Fusion on the Velocity Profile of a Disk Galaxy

I have decided to rescind this proposal.  Stars in a galaxy travel at one velocity, light at the speed c.  There is only one velocity involved in applying the product rule to the definition of a force as a change in momentum.  Note that is not a trivial a ...

Two Higgs After All? A New Signal From CMS!

What looks like a tantalizing signal of the rare two-muon decay of the Higgs boson has been evidenced in an analysis of 2011+2012 data just sent to PRL by the CMS collaboration. This analysis targeted supersymmetric neutral Higgs bosons, whose decay to muo ...

The Higgs Lottery

The mediatic effect of the Higgs boson discovery of last July is clear to everybody. And CERN has been very good at exploiting it, making fundamental physics a familiar topic and creating interest worldwide. Yet I think we can do more. The gap between basi ...

Dark matter non-results of the Alpha Magnetic Spectrometer and ANTARES. What these two observations really mean for dark matter.

The Alpha Magnetic Spectrometer has found is that there are interesting features in the cosmic ray background which could indicate dark matter particle anti particle annihilations.  That is not the same as finding dark matter.   The ANTARES neutrino telesc ...

11 Electron Neutrinos In T2K!

The T2K Collaboration released today an analysis of their data in the Cornell Arxiv. T2K searches for electron neutrinos appearing in a muon neutrino beam produced by the J-PARC accelerator facility in Tokai-Mura, using a near detector located 280 meters d ...

Sterile Neutrinos: Toward A Clarifying Experiment

Now that the Higgs has been found, the current hype in popular science magazines suggests that the most pressing question in fundamental physics research is whether new particles will be found at the Large Hadron Collider: Is Supersymmetry the right extens ...

A Sense Of Scale

There have been other attempts in the past, so this is not strictly a new idea. However I found the interactive web page at http://htwins.net/scale2/ extremely well constructed. It is a graphical display of the largest and smallest structures from galaxy s ...

Gamma Ray Flashes And Dark Lightning

"What are the radiation doses to airplane passengers from the intense bursts of gamma-rays that originate from thunderclouds?" researchers asked at a press conference during the European Geosciences Union in Vienna today. ...

Dark matter and dark energy, or Pre-Big Bang geometry?

Results from Planck and AMS-02, but also the way they are often presented, have created a very exciting situation. Its exceptional character has led me to quickly write an article, Planck data, spinorial space-time and asymptotic Universe, and to make it ...
