New results from the CMS experiment put W boson mass mystery to rest

Gluon discovery

This collision event recorded in 1979, provided the first evidence of the gluon, the carrier of the strong nuclear force.

Collisions galore

In May, Fermilab accelerator experts began to speculate about when the Tevatron collider would hit the inverse femtobarn mark, a measure of the gazillions of collisions produced since March 2001.

Postcards from the terascale

In February, the Department of Energy's Office of Science and the National Science Foundation asked the High Energy Physics Advisory Panel "to form a committee to write a document" that addresses the synergies and complementarities of the Large Hadron Collider, now under constructi

Researching the ILC

Research papers are traditionally written about data gathered in an experiment. However, research papers are also published before an experiment has even begun, and the International Linear Collider is an example.

Global ILC efforts

Designing the International Linear Collider is a global enterprise. Physicists and accelerator experts from around the world are collaborating to design the approximately 25-mile-long machine.

Tied with reed

What do a 200-year-old thatched-roof house and a modern high-energy-physics laboratory have in common?

In their hands: the future of particle physics

Particle physics is at a critical time, and its future depends on how well scientists can make their case to a diverse National Academy of Sciences panel.

Busloads of new Stanford graduates and their families admired the field of golden grass on SLAC's eastern-most hill on a sunny Saturday in May. But their stunned tour guides looked in dismay as they sought 50 bright red balloons.
