Physics

For this instance of my "Guess the plot" series I wish to go back to the basics. So I picked a graph which allows me to illustrate a general concept, something about particle physics (but we could say physics in general, and actually extending to ...

Dark Energy, Dark Matter, Dark Force: Not Afraid Of The Dark

One problem with the acceptance of dark energy and dark matter is that they are presented as if they are brothers, as if presenting merely the start of a new line of cheap ad hoc fudge factors: Dark energy, dark matter, dark force, what next? However, dark ...

What's Wrong With The Second Law?

Use your browser's back button and stop reading when you can't handle speculations out of a hammock. Still reading? Ok, I have warned you. Brace yourself. I am going to argue against what many believe to be the most fundamental law of physics. A ...

Single Top: As Good As It Gets At The Tevatron

Like it or not, the Tevatron is going to shut down for good next month. This machine has provided us with tremendous new investigation power in the high-energy frontier of particle physics, and has led the research of hadronic collisions for over two decad ...

Notes On Higgs Branching Fractions

In my latest instantiation of the "Guess the plot" series I offered a clipped part of a graph showing branching fractions of the Higgs boson. One of the readers made a comment which I was proud to read, since it showed that interested readers of ...

New ATLAS Limits On Higgs Mass

Much awaited, the results of searches for the Higgs boson at the Large Hadron Collider have been released by the ATLAS collaboration, and are being shown at the Lepton-Photon conference in Mumbay, India. I will provide here just the main results, with litt ...

New CMS Limits On Higgs Mass

I have written enough today about the topic of Higgs boson searches at the LHC by discussing the new ATLAS limits (see previous post), but I feel that, before going to bed, I need to point out the new results on the same topic by CMS, the competitor experi ...

Steven Weinberg and I

I don't like Steven Weinberg. Good, I have said it. I will provide a brief biographical sketch and a short list of his lengthy accomplishments. I read one of his science outreach books, " Dreams of a Final Theory: The Search for the Fundamental ...

The Say Of The Week

" In a world of string theory, I can be the Pope [...]. I just need to modify dilatonic Einstein-Gauss-Bonnet theory with low-energy heterotic string theory and it's all quite easy." H. Campbell ...

The Plot Of The Week- Heavy Particle Production In ATLAS

If you work in experimental high-energy physics you soon acquire a particular sensitivity to the economical display of relevant information. Producing figures that convey the most meaning with the minimum effort is sort of an art, and it is a necessary con ...
