![]() The IceCube Neutrino Observatory in Antarctica, which looks for rare neutrinos produced when cosmic rays hit particles in Earth’s atmosphere, might also need to take this new structure into account, says Rojo. The proton’s charm component could also have ramifications for other physics experiments at the LHC, says Cliff, as they rely on accurate models of proton substructure. ![]() “Given how ubiquitous this particle is and how long we’ve known about it, there’s still a lot we don’t actually understand about its substructure, so this is definitely important,” says Harry Cliff at the University of Cambridge. “The fact that very different studies converge on the same result made us especially confident that our results were solid,” says Rojo. This means they are more confident in proposing the presence of a charm quark than the sigma level by itself suggests. They found the model better matched the results if the proton is assumed to have a charm quark. ![]() ![]() The team looked at recent results from the LHCb Z-boson experiment and modelled the statistical distribution of the proton’s momentum both with and without a charm quark. Ten years after the Higgs discovery, what now for particle physics?
