Large Extra Dimensions At Reach Next Year!

A new public document has been made available on the CMS public web page yesterday morning. It reports on a study of the reach of the CMS detector, with data collectable in 2010, for a signal of large extra dimensions, using the very distinctive signature ...

The blogosphere misses what peer review hits... for once.

I posted a very short rough paper here a while back.  " Dark Matter and Energy as Particles and Fields of Unobserved Scalar and Vector Fields (PDF) (rev2).." Since then certain comments and supposed extremely elementary errors have been pointed o ...

Just One Higgs Search Plot...

...waiting for a piece I will post tomorrow, to stimulate your curiosity-and allow me to travel from Venice to Patras by ship, with no internet connection. The subject is not only the Higgs mass, but the top quark mass. Which top mass? The "pole" ...

Running Top Mass Points To SUSY-Like Higgs

Yesterday I posted a short article whose main purpose was to show a figure I had received from Sven Heinemeyer, a phenomenologist who specializes in the study of Minimal Supersymmetric extensions of the Standard Model (MSSM). Besides predicting a mirror co ...

The Nuts And Bolts Of The "Nail The Higgs Down" Plot

As silly as it may look, I am going to start this post by publishing for the third time in a row the same figure. That is because I want to keep the promise I made earlier that I would explain in terms as simple as possible (although not simpler) the detai ...

B-Quark Jets: Keys To New Discoveries

In this two-parts article I wish to describe in some detail, but still at an elementary level, the characteristics of one of the most important probes of the physics of subnuclear collisions at today's particle physics experiments: jets of hadrons ori ...

Forget Galileo: You Are A Star, Lyman Strong Spitzer, Jr.

In Toledo, Ohio on June 26, 1914-- a star was born. He was named Lyman Strong Spitzer, Jr. for good measure. An asteroid, a space telescope, and a building in the Princeton Plasma Physics Laboratory (PPPL) bear his name today. His theoretical and applied r ...
