From CERN Blog at Quantum Diaries: “How is new physics discovered?”

IT HAS BEEN A WHILE SINCE I HAVE BEEN ABLE TO PRESENT A POST FROM QUANTUM DIARIES. MY AUDIENCE IS A MORE GENERALIST PUBLIC – INTERESTED, EDUCATED, BUT NOT PROFESSIONAL SCIENTISTS. NOW COMES A POST WHICH I BELIEVE MIGHT BE APPROACHABLE FOR MY READERS.

“Finding an experimental anomaly is a great way to open the door to a new theory. It is such a good trick that many of us physicists are bending over backward trying to uncover the smallest deviation from what the current theory, the Standard Model of particle physics, predicts.

This is the approach the LHCb collaboration at CERN is pursuing when looking at very rare decays. A minute deviation can be more easily spotted for rare processes. One good place to look is in the rate of K meson decays, a particle made of one strange quark s and one anti-down quark d.

Recently, the LHCb collaboration has turned its attention to measuring the decay rate of the short-lived kaons K0S, the only K mesons decaying fast enough to be seen with precision in their detector.”

I hope that is enough to entice you to read further.
