LHC antimatter anomaly hints at new physics ":
"The Large Hadron Collider has turned up differences in how particles of matter and antimatter decay that the reigning standard model of physics may not be able to explain
New Scientist says:
"It is one the biggest mysteries in physics - where did all the antimatter go? Now a team of physicists claims to have found the first ever hint of an answer in experimental data."
"According to our current picture, the big bang produced both particles and antiparticles in equal amounts, most of which mutually annihilated to release energy. At some point, some unknown factor must have led there to be slightly more particles than antiparticles"
