A new observation by the LHCb experiment finds that charm quarks behave differently than their antiparticle counterparts.

Our best model of particle physics explains only about 5 percent of the universe.
The Japan-based experiment is one step closer to answering mystifying questions about antimatter.
Through hard work, ingenuity and a little cooperation from nature, scientists on the BASE experiment vastly improved their measurement of a property of protons and antiprotons.
From CNN, July 22, 2017: Fermilab scientist Don Lincoln explains how the Deep Underground Neutrino Experiment, which had its groundbreaking ceremony on July 21, could answer important questions of the universe, including, “Where did the antimatter go?”.
Experiments at CERN investigate antiparticles.
From Wired, April 5, 2017: For some reason, more matter formed than antimatter just after the Big Bang, and physicists don’t know why. “It’s one of the very biggest mysteries in the universe,” says physicist Don Lincoln of Fermilab.
From Science, March 6, 2017: For more than a decade, multiple experiments have found an unexpected excess in the number of high-energy antielectrons, or positrons, in space. A team led by Fermilab’s Dan Hooper has shown that pulsars, not dark matter annihilation, can indeed produce most or all of the excess.
A result from the LHCb experiment shows what could be the first evidence of matter and antimatter baryons behaving differently.
Measuring with high precision, physicists at CERN found a property of antiprotons perfectly mirrored that of protons.
