A communication resource from the world's particle physics laboratories.
On and around October 31, 2017, the world will celebrate the historic hunt for the unseen—something that scientists refer to as dark matter. Local events planned by institutions and individuals around the planet will engage the public in discussions about what we know about dark matter, and about the many present and planned experiments that seek to solve its mysteries.
New result rivals precision of cosmic microwave background measurements, supports view that dark matter and dark energy make up most of the cosmos.
Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof that you were right . . .
With the turning of a shovelful of earth a mile underground, a new era in international particle physics research officially began Friday, July 21.
In a unique groundbreaking ceremony held at the Sanford Underground Research Facility in Lead, South Dakota, a group of dignitaries, scientists and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. The Long-Baseline Neutrino Facility (LBNF) will house the international Deep Underground Neutrino Experiment (DUNE), which will be built and operated by a group of roughly 1,000 scientists and engineers from 30 countries.
The LHCb experiment at CERN’s Large Hadron Collider has reported the observation of Ξcc++ (Xicc++) a new particle containing two charm quarks and one up quark. The existence of this particle from the baryon family was expected by current theories, but physicists have been looking for such baryons with two heavy quarks for many years. The mass of the newly identified particle is about 3621 MeV, which is almost four times heavier than the most familiar baryon, the proton, a property that arises from its doubly charmed quark content. It is the first time that such a particle has been unambiguously detected..

It’s less of a collision and more of a symphony...
In particle physics, the term “collide” can mean that two protons glide through each other, and their fundamental components pass so close together that they can talk to each other. If their voices are loud enough and resonate in just the right way, they can pluck deep hidden fields that will sing their own tune in response—by producing new particles.
This report distills the findings of a series of international peer reviews of the communications and outreach functions of large-scale multidisciplinary science laboratories around the world.
