Last year, two teams working at the LHC reported that they had found proton-to-proton collisions that had led to the creation of more photon pairs (with energies of approximately 750 GeV) than was expected, leading to theories that the evidence might be pointing to a new particle than no one has theorized. This discovery led to a plethora of teams creating papers seeking to be the first to explain this seeming anomaly—so many papers have been submitted to journals for publication that editors have had to pick and choose which to publish. One example is Robert Garisto with Physical Review Letters, who has published an editorial describing the onrush and the decision to publish just four papers in their latest edition, which the editorial team believes is representative of the four main ideas.
In the first paper, Christoffer Petersson with Chalmers University of Technology in Sweden and Riccardo Torre with Institut de Théorie des Phénomènes Physiques in Switzerland, suggest the bump represents the existence of a boson with very weak interactions that is possibly a supersymmetric partner of the still hypothetical fermion called the goldstino.
