Researchers may have uncovered a potential fifth force of nature that has the potential to revolutionize our understanding of the universe.

Scientists have recently drawn a rather unexpected conclusion about one of the subatomic particles, the muon. This finding indicates that there might exist another five force of nature in addition to the forces that are known.

The four fundamental forces in nature which include the electromagnetic force, strong nuclear force, weak nuclear force and gravity are by the particle model. Still, this model does not take into consideration dark matter which comprises about 27% of the universe.

The sources of evidence for the possibility of the existence of the fifth force are experiments that were carried out at the FermiLab US Particle Accelerator Laboratory. Scientists were more concerned with examining the reaction of muons, which are heavy electrons, to a magnetic field.

Based on the standard model, the muons should rotate at a certain frequency and in a specific direction. Nevertheless, the researchers noted that muons rotated at a higher rate than expected, suggesting the presence of another particle or force that is not yet recognised.

Dr. Mitesh Patel, a scientist at Imperial College London, said that it is named the fifth force because the observed behaviour cannot be accounted for by other four forces.

Further, Professor Jon Butterworth, who is working on the Atlas experiment in Large Hadron Collider at Cern, said that increase in spinning of muons is caused by magnetic field. Although this interaction can be quantitatively described in the standard model, it entails quantum circles with recognized particles.

It this doesn’t match with the calculations, then it indicates that there could be a new particle within these loops. Scientists believe that this new particle can be the carrier of the assumed fifth force.

The findings from FermiLab align with previous results obtained from the same facility. However, Patel expressed concern regarding the increasing uncertainty surrounding the theoretical prediction of the muon’s frequency over time.

“This could potentially alter the situation. It is possible that what they are observing is in line with conventional scientific thinking, commonly referred to as the standard model,” Patel stated.

There are additional challenges to consider. Butterworth explained, “If the discrepancy is verified, it would indicate the presence of something new and intriguing, although the exact nature of it would remain unknown.”

“Ideally, this difference would inspire new theoretical concepts that could lead to fresh predictions. For instance, it could help us determine how to detect the particle responsible for this new force, if indeed that is what it is. The ultimate confirmation would involve constructing an experiment specifically designed to directly discover this particle.”

The experiments conducted at FermiLab are not the sole indicators of a potential fifth force. Research conducted at the LHC has also yielded interesting findings, albeit through a different type of experiment that examines the frequency of muons and electrons produced during the decay of certain particles.

Patel, who was involved in the LHC experiments, noted that these results were now less consistent.

“These are distinct experiments, measuring different aspects, and it remains uncertain whether there is any connection between them,” he explained.

Butterworth further emphasized that the discrepancy between the measured and predicted frequency of the muon represents one of the oldest and most significant gaps between observation and the standard model.

“The observation itself is a remarkable accomplishment and highly unlikely to be erroneous at this point,” he stated. “Therefore, if the theoretical predictions can be resolved, this could potentially serve as the initial confirmed evidence for a fifth force, or perhaps something else extraordinary and beyond the standard model.”
