New Evidence of an Unknown Particle That Could Carry a Fifth Force of Nature

Fresh evidence of an unknown particle that would carry the fifth power of nature offers the NA64 collaboration at CERN a new reason to proceed searches.

In 2015, a crew of scientists spotted an unexpected glitch, or “anomaly,” in a nuclear transition that might be defined by the production of an unknown particle. About a year later, theorists suggested that the new particle may very well be proof of a brand new fundamental force of nature, along with electromagnetism, gravity and the strong and weak forces.

The findings caught worldwide consideration and prompted, amongst different research, a direct search for the particle by the NA64 collaboration at CERN.

A new paper from the same group, led by Attila Krasznahorkay on the Atomki institute in Hungary, now reports one other anomaly, in a similar nuclear transition, the same hypothetical particle may explain that.

The NA64 collaboration looks for X17 by firing a beam of ten billions of electrons from the Super Proton Synchrotron accelerator onto a hard and fast goal. If X17 might exist, the interactions between the nuclei and electrons within the target would generally produce this particle, which might then rework into an electron-positron pair.

The collaboration has to this point discovered no indication that such occasions happened; however, its datasets allowed them to exclude a part of the potential values for the power of the interaction between X17 and an electron. The group is now upgrading their detector for the next round of searches, that are expected to be tougher however on the similar time more exciting
