Physics

A quick cross link to a great article on the Higgs boson search at the super liberal web site dailykos.com. A very clear description of the issues. I particularly liked the stats. One other thing to note: the threaded discussion had 433 comments. Those fol ...

A New Beautiful Baryon Bagged By CDF

This afternoon (2.30 PM Chicago time) Pat Lukens, an old-timer of the CDF experiment, will give a "wine and cheese" seminar at Fermilab on the new observation of a heavy baryon, of the family of baryons containing bottom quarks, which was still a ...

Wiedemann-Franz Law Broken After 150 Years

The Wiedemann-Franz Law, named after German physicists Gustav Wiedemann and Rudolf Franz, is a ratio of the thermal to electrical conductivities of metals. In 1853, the two studied the thermal conductivity, a measure of a system's ability to transfe ...

Top Quark Asymmetry? No Thanks, Says CMS

Impressive. If you had been seeking for top quarks in 4-inverse-picobarns datasets since 1992 as I have, and then rejoiced at the 7-event signal from which CDF extracted in 1994 mass and cross section of the long-sought sixth quark, you would now also be l ...

Five New Higgs Searches By CMS!

An orgy of new results has started. Let me just show a few of them concerning Higgs searches in CMS- I am on vacation after all, and I have little time left to comment these interesting new papers and plots after all the sunbathing and restaurants. Let us ...

One More Higgs Search: H To Four Leptons

In my short summary of analyses recently published by CMS, yesterday I left out one which had not yet been released. It is the search for the "golden channel" of Higgs decay, the one which motivated the construction of detectors with large accept ...

From Big Bang To Cosmic Crackerpack

Equations don't sell. Pop science editors tell us that each equation added to a book halves its sales figure. If this is true, Sir Roger Penrose's Cycles of Time, which was recently released in the US, and which I can testify sold at least one co ...

Combined Higgs Search Limits, Circa 2011

In the last few days I described in some detail (here and here) the six searches for the Standard Model Higgs boson just produced by CMS, the experiment at the CERN Large Hadron Collider to which I proudly belong. ...

The Hilbert Book Model

This paper introduces a new model of physics. It is based on logic. It uses the congruence between the logic of quantum physics and a mathematical construct that got its name from David Hilbert. The Hilbert book model extends this construct such that field ...

Mini Blog: Betting Against the House

If you haven't already, go enjoy Hank's blog, " Higgs Boson- Forget Science, What Do Bookies Think? ". He answered what was the most pressing question to me: one cannot bet that no Higgs will be found. That is a shame, since all previou ...
