‘Conceptually, particle physics experiments are surprisingly simple. Smash a shitload of particles together, and look at what comes out. The results will either confirm whatever the business-as-usual theory is, or, if there’s a really crystal clear deviation from that theory, they might prove some new hypothesis about some new particles. But the middle ground, where the difference between what we know and what we see is still fuzzy, is where lots and lots of results live.
New results from LHCb, one of the experiments observing particle collisions at the Large Hadron Collider in Geneva, Switzerland, are showing one such fuzzy discrepancy. Physicists are cautiously excited, because if these results hold up, they would imply the existence of some brand-new particles. Unlike last year, when a small signal that seemed like it could have been something new turned out to be just a statistical fluke, these new results are popping up in the wake of another hint observed in a different way a few years ago that hasn’t gone away. So, this time, there may really be something there.
If these signals do turn out to indicate real discoveries, it might “imply the existence of some new kind of particles or other physics that’s still unknown,” LHCb physics coordinator Vincenzo Vagnoni told Gizmodo. “This is a way to unveil the existence of a new family of particles.” …’
