Dark Matter explained by extra dimension in spacetime and a new heavy particle similar to the Higgs Boson?

Scientists from the University of Granada (UGR), Spain, and the Johannes Gutenberg University Mainz, Germany, have recently published a study in which they endeavor to extend the Standard Model of particle physics (the equivalent of ‘the periodic table’ for particle physics) and answer some of the questions that this model is unable to answer. Such puzzles include: What is dark matter made of? Why do the various constituents of fermionic dark matter have such different masses? Or, why is the force of gravity much weaker than electromagnetic interaction?

Unlike the Higgs boson, discovered at CERN’s Large Hadron Collider in 2012 after a 40-year quest, the new particle proposed by these researchers is so heavy that it could not be produced directly even in this collider. (SciTechDaily)
