Madala Boson: Physicists Predict Existence of New Heavy Particle

An international team of physicists, led by the University of the Witwatersrand (UW) in Johannesburg, South Africa, predicts the existence of a new particle that might aid in the understanding of dark matter.

Using data from a series of experiments that led to the discovery of Higgs boson at the Large Hadron Collider (LHC) at CERN in 2012, Prof. Bruce Mellado of UW’s High Energy Physics Group and co-authors established what they call the Madala hypothesis.

“The discovery of the Higgs boson has opened the door into making even more ground-breaking discoveries, such as the observation of new bosons that are linked to forces and particles unknown before,” the physicists said.

“These new particles can explain where the unknown matter in the Universe comes from.”

The team’s hypothesis describes the existence of a new heavy boson and field.

The hypothetical particle, dubbed Madala boson, has a mass of about 272 GeV – slightly more than two times heavier than the Higgs boson.

“However, where the Higgs boson in the Standard Model only interacts with known matter, the Madala boson interacts with dark matter,” the scientists said.

“Physics today is at a crossroads similar to the times of Einstein and the fathers of Quantum Mechanics,” Prof. Mellado added.

“Classical physics failed to explain a number of phenomena and, as a result, it needed to be revolutionized with new concepts, such as relativity and quantum physics, leading to the creation of what we know now as modern physics.”

Prof. Mellado and co-authors presented their latest results recently at the 61st Annual Conference of the SA Institute of Physics in Johannesburg and the 38th ICHEP in Chicago.
