Moore's Law, originating in 1965 [1], is an observation of transistor density on a single CPU core increasing exponentially with time. Futurists such as Ray Kurzweil [2] extend this to the claim that CPU-core computation rate (operations per second) ...

Highlights From The CMS Experiment

Three weeks ago I gave a plenary talk at the 2nd International Conference on New Frontiers in Physics, which was held in Kolymbari, in the greek island of Crete. The talk focused on some of the most interesting new results by the CMS Collaboration, but bei ...

First Experimental Determination Of Proton Weak Charge Determined

Researchers are reporting the first experimental determination of the weak charge of the proton, one of the four fundamental forces in our universe, along with gravity, electromagnetism and the strong force. Although the weak force acts only on the sub-at ...

A Privileged Space Direction? Spinorial Space-time, WMAP, Planck (II)

How to present in a simple way the spinorial space-time and the privileged space direction it generates? What is the fundamental difference between space-time spinors and the conventional description of space and time? What is the relevance for the analysi ...

ATLAS Limits On Dark Matter

The ATLAS Collaboration published last week the results of a search for dark matter particles produced in association with a W or Z boson by the 8-TeV proton-proton collisions collected during the 2012 run of the Large Hadron Collider. The search uses tech ...

DZERO Confirms The Y(4140) And Its Excitation!

I have reported about the studies of resonances in the decays of the B+ meson by CDF, CMS, and LHCb a few times in the recent past. The situation, in a nutshell, was the following until yesterday: CDF found a new particle, the Y(4140), as a resonant (J/ψ φ ...

Confidence In New Physics And SUSY Dropping Like A Stone

UPDATE: Just found out that Peter Woit anticipated me on this- see his blog entry.--- Just five years ago, on the eve of the start of the Large Hadron Collider, most particle physicists- experimentalists and theorists alike- would have been willing to bet ...

What You Think Of New Physics At The TeV Scale

A few days ago I posted the results of a poll ran on 50 or so participants to a workshop on the Higgs boson in Madrid. The poll consisted of six questions on the expectations one had on the possibility of new discoveries by present-day accelerators, as wel ...

Scalar-Tensor Theories: Maybe Black Holes Do Have 'Hair'

In 1963, Roy Kerr's hypothesis was of a "clean" black hole model and that remains the dominant paradigm. From theory to reality things may be quite different, black holes may be much "dirtier" than what Kerr believed, the authors ...

Accelerator on a chip? Not so fast.

Most stories on the so called "accelerator on a chip" either fail to mention or deeply bury an important detail.     This device needs to be primed by a conventional accelerator.   In doing so, they give the wrong impression of what has been deve ...
