More data, no problem

Scientists are ready to handle the increased data of the current run of the Large Hadron Collider. Physicist Alexx Perloff, a graduate student as Texas A&M University on the CMS experiment, is using data from the first run of the Large Hadron Collider for his thesis, which he plans to complete this year.

What is dark energy?

It’s everywhere. It will determine the fate of our universe. And we still have no idea what it is. Looking up at the night sky reveals a small piece of the cosmos—patches of stars speckled across a dark, black void. Though the universe...Show More Summary

The wonderful thing about triggers

Physicist Jim Pivarski explains how particle detectors know when to record data. Imagine you're a particle physicist in 1932. You have a cloud chamber that can show you the tracks of particles, and you have a camera to capture those tracks for later analysis. Show More Summary

Higgs factory proposed for Beijing

Scientists in China hope to build a successor to the Large Hadron Collider—and take a new place on the international particle physics stage. The discovery of the Higgs boson was one of the biggest moments in the history of particle physics. Show More Summary

How do you solve a puzzle like neutrinos?

When it comes to studying particles that zip through matter as though it weren’t even there, you use every method you can think of. Sam Zeller sounds borderline embarrassed by scientists’ lack of understanding of neutrinos—particularly how much mass they have. “I think it’s a pretty sad thing that we don’t know,” she says.

Exploring dark energy with robots

The Dark Energy Spectroscopic Instrument will produce a 3-D space map using a ‘hive’ of robots. Five thousand pencil-shaped robots, densely nested in a metal hive, whir to life with a precise, dizzying choreography. Small U-shaped heads...Show More Summary

Seeing in gamma rays

The latest sky maps produced by Fermi Gamma-ray Space Telescope combine seven years of observations. Maps from the Fermi Gamma-ray Space Telescope literally show the universe in a different light. Today Fermi’s Large Area Telescope (LAT)...Show More Summary

Bringing neutrino research back to India

The India-based Neutrino Observatory will provide a home base for Indian particle physicists. Pottipuram, a village in southern India, is mostly known for its farming. Goats graze on the mountains and fields yield modest harvests ofShow More Summary

Mathematician to know: Emmy Noether

Noether's theorem is a thread woven into the fabric of the science. We are able to understand the world because it is predictable. If we drop a rubber ball, it falls down rather than flying up. But more specifically: if we drop the same...Show More Summary

Making the portable gamma camera

The end of the Cold War and the cancellation of the Superconducting Super Collider led to the creation of a life-saving medical device. Each year, more than 5 million Americans take a nuclear heart stress test, which images blood flow in the heart before and after a brisk walk on a treadmill. Show More Summary

OPERA catches fifth tau neutrino

The OPERA experiment’s study of tau neutrino appearance has reached the level of “discovery.” Today the OPERA experiment in Italy announced a discovery related to the behavior of neutrinos. Light, rarely interacting particles called neutrinos come in three types, called “flavors”: electron, muon and tau. Show More Summary

Q&A: New director-general of KEK

Masanori Yamauchi started his three-year term as head of Japan’s major center of particle physics research this spring. Courtesy of: KEK At a recent symposium about the proposed International Linear Collider, Symmetry chatted with Masanori Yamauchi, the new director-general of KEK, Japan’s high-energy accelerator research organization.

LHC physicists preserve Native American voices

Physicists are using LHC detector technology to retrieve Native American music from old recordings. Berkeley physicist Carl Haber listened in astonishment as the first notes of the 1950s hit “Goodnight Irene” played through his computer. “It...Show More Summary

Japan’s next big neutrino project

The proposed Hyper-K experiment would dwarf its predecessor. In 1998, the Super-K detector in Japan revealed that ubiquitous, almost massless particles called neutrinos have the ability to morph from one type to another. That landmark...Show More Summary

Steady to a fault

How do accelerators survive in some of the most earthquake-prone regions on Earth? Perhaps you’ve seen the trailer for San Andreas, a movie in which a massive quake rocks northern California, toppling skyscrapers and propelling a massive...Show More Summary

The universe at your fingertips

Raw images from the DECam Legacy Survey’s new image archive will appear online the day after they are taken. When it was time to celebrate the 20th anniversary of the Star Wars trilogy, director George Lucas was prompted by technological...Show More Summary

LHC arrives at the next energy frontier

Data collection has officially begun at the Large Hadron Collider. Today the Large Hadron Collider began collecting data for the first time in two years. The world’s most powerful particle accelerator powered back on in April and saw its first record-energy collisions in May. Show More Summary

Inside particle detectors: calorimeters

Physicist Jim Pivarski explains how particle detectors tell us about the smallest constituents of matter. The previous article in this series introduced tracking, a technique that allows physicists to see the trajectories of individual particles. Show More Summary

Inside particle detectors: trackers

Fermilab physicist Jim Pivarski explains how particle detectors tell us about the smallest constituents of matter. Much of the complexity of particle physics experiments can be boiled down to two basic types of detectors: trackers and calorimeters. Show More Summary
