3 May 2012Empty space is anything but. Remove everything you can from an area of space and it will still bustle with activity. A veritable abundance of particles and all-pervasive fields fill space with energy. Empty space even weighs something. Indeed, studying ‘nothing’ can tell us almost everything about the universe we live in. Learn more about the relationship between vacuum and “virtual” particles, the Higgs boson, supersymmetry and dark energy

5 April 2012While people often grasp only a fraction of the physics at stake, they easily recognise the full extent of the human undertaking. Particle-physics experiments and accelerators are, indeed, miracles of technology and major examples of worldwide co-operation and on-site teamwork.

Leah Hesla | 1 March 2012We don’t usually notice all three dimensions of a semiconductor chip. We note the intricate, maze-like circuitry imprinted onto one side or its reflective sensor surface. Rarely is attention paid to its depth, mostly because chips have so little of it. In the last five to ten years, the particle detector community has been working with the semiconductor industry to develop sensors’ minuscule depths to create technology with integrated functionalities that could be used in fields outside particle physics.

23 February 2012Meetings for the International Linear Collider Steering Committee and the International Committee for Future Accelerators recently took place in Oxford, England. One of the principal issues discussed at both meetings was a new organisation for the worldwide linear collider effort.

Perrine Royole-Degieux | 16 February 2012The international community of theorists and experimentalists working on ILC and CLIC is convinced of the strong physics case for a generic linear collider. More than one hundred of them gathered at DESY last week for three days of intense discussions and review of the different physics scenarios. Two papers are now under way and will be finalised by this summer. In the meantime the input from the whole particle physics community will be very welcome.

Leah Hesla | 9 February 2012Designing a 1-TeV upgrade of the ILC requires a suitable particle beam to go along with it. Scientists recently decided on the shape of the 1-TeV beam, and it has a shifted waist.

19 January 2012If you have even the faintest interest in particle physics, you've heard about the Higgs boson. The Higgs boson is the leading candidate explanation for the origin of the masses of point-like subatomic particles. By extension, the Higgs boson is the origin of mass in the universe, right? There's only one problem with that statement—it's totally wrong. Read the full article in Fermilab Today.
