Cosmologists Say They Have Support For Dark Matter

Researchers using measurements of the cosmic microwave background- a faintly glowing relic of the hot, dense, young universe- say their results provide support for the cosmological model of the universe- a prediction that dark matter and dark energy make u ...

The Continuing Quest For Flavor-Changing Neutral Currents

These days the Higgs boson search is a bit over-hyped, with the impending competition between Tevatron and LHC on the discovery of the fabled boson making headlines every time there is a new, even minor, update in the results of the CDF and D0 experiment. ...

Learn To Compute Higgs Limits On The Fly

I am presently into the second week of my lessons of Subnuclear Physics for the 2nd year of specialization in Physics, and I have just finished a lesson discussing the current searches for the Higgs boson at the Tevatron collider. Since the course has a fo ...

The Say of the Week: Lederman's Shoulder

"The yield of muon pairs decreased rapidly from 1 GeV to the kinematic limit of nearly 6 GeV with the exception of a curious shoulder near 3GeV. The measurement of muons was by range as determined by liquid and plastic scintillation counters intersper ...

Why Physicists Like Ratios

A good part of basic research in fundamental physics focuses on the definition, the prediction, and the measurement of quantities which put the current theory-the standard model- to the test in the most stringent way possible. The choice of the quantities ...

What is going on around

Today, having little inspiration to write anything original myself, I decided to have a look at what other sites held by colleagues or friends are dealing with. I offer below a few interesting links, with minimal commentary. Peter Woit is always more infor ...

Understanding Newtonian Mechanics

Newtonian mechanics has marked the beginning of a new era for physics. Indeed the newtonian formulation of the gravitational force has allowed to prove the heliocentric theory developped by Copernicus and defended by Galileo. It is a very interesting story ...
