This is very interesting indeed. I don't see how they directly conclude that the anomaly in the number of pairs of electrons and positrons implies a new particle. If this is indeed not an anomaly, then I think they should be getting a similar result if they increase the speed of collision, albeit at a different angle. Although if this super light boson is in fact the real deal, then it would shed a lot of light into the topic of dark matter (hue hue) which has been very mysterious and elusive till now. Of course, there is no solid rule stating that this new boson would have to carry a new forc
