Antimatter Results Emerge at LHC - but Puzzle Abides
The quest to understand why our Universe is made of matter rather than antimatter has received a boost at the Large Hadron Collider.
The LHCb experiment has for the first time observed decays of particles known as Bs mesons that preferentially end up as matter, rather than antimatter.
However, the difference is still not enough to explain the preponderance of matter over antimatter in the cosmos.
The work, published online, has been submitted to Physical Review Letters.
Every member of the zoo of particles we know about has an antimatter cousin, identical in mass but with opposite electric charge - the electrons and protons that in part make us up have positrons and antiprotons as their antimatter matches.
