While studying dark matter, a team of scientists has discovered signs of a new particle named Madala boson which might solve the mystery of dark matter that has kept scientists baffled for so long.
Higgs boson is another fundamental particle of dark matter that was discovered by a series of experiments back in 2012 at the European Organisation for Nuclear Research (CERN). During the same series of experiments, researchers also developed Madala hypothesis which tells about a new boson particle.
To confirm it, researchers again conducted the experiments last year and this year. “Based on a number of features and peculiarities of the data reported by the experiments at the LHC and collected up to the end of 2012, the Wits HEP group in collaboration with scientists in India and Sweden formulated the Madala hypothesis,” said Professor Bruce Mellado, team leader of the High Energy Physics (HEP) group at University of the Witwatersrand in Johannesburg.
According to the hypothesis, a new particle exists which is similar to Higgs boson. While explaining, researchers said that Higgs boson interacts with known particles in the universe which make it easier to identify. However, the Madala boson particle interacts with the elusive dark matter which constitutes 27 percent of our universe.
Particles like Higgs boson and Madala boson are mentioned in the Standard Model of Physics which deals with fundamental interactions in nature. Discovery of Higgs boson in 2012 won the Nobel prize in Physics in 2013.
Although, the discovery of Higgs boson completed the Standard model of Physics but still the model fails to explain about dark matter.
The universe is made up of two things — mass and energy. The mass that we can touch, smell and see, the mass that can be explained by the Higgs boson, makes up only 4 per cent of the mas-energy budget of the universe. The rest of the mass in the universe is simply unknown, yet it makes about 27 per cent of the world around us.
The next big step for the physics of fundamental interactions now is to understand the nature of dark matter in the universe, said scientists including Deepak Kar and Xifeng Ruan, who have years of expertise at the LHC.
