Scientists trace cosmic cold dark matter is unknown.

Scientists tracking a cold dark matter universe from an unknown Chinese Academy of Sciences, Institute of High Energy Physics, Tsinghua University, China Institute of Atomic Energy of 9 units consisting of nearly 25 experts cooperation group has been established, they will soon launch a world of objects and particles .physics and space science community attaches great importance to research the most popular: Tracking is possible that the early universe after the explosion has left the weak role of heavy particles - supersymmetric particles. .Once it has been repeatedly confirmed that the weak scientific role of heavy particles do exist, will greatly support the model of supersymmetric particles. .Regardless of the outcome, for which the search for new particles in particle physics, astrophysics and cosmology of the development is of great scientific significance. .In co-operation of the project has any group in China's chief scientist, researcher at the Institute of High Energy Physics, Chinese Academy of Dai Changjiang calm discourse, shows a very easy to feelings of expectation and excitement. .The mystery of cold dark matter from atomic physics to nuclear physics, to today's particle physics, physics is improving have been able to explain a lot of good movement of celestial objects such as the complex nature of natural phenomena. .Cosmological model, the universe after the big bang through the ultra-high energy, high energy, low energy process, the corresponding physical laws are consistent with grand unification, weak unification and quantum chromodynamics, the Big Bang and evolution of the particles generated by these laws are followed .. .However, in the universe may exist some weak effect of cold dark matter particles, their formation and movement of an existing model of particle physics can not explain, so scientists have proposed a model of supersymmetric particle physics. .Explosion of modern astronomical observations and cosmological studies have shown that the vast majority of the material universe, dark matter, while the majority of dark matter is cold dark matter particles by the non-baryonic dark matter, and now the prevailing view that such cold dark matter particles in the universe .The content of more than 20%. .Dai Changjiang researcher, said to reporters, though? </ P>.
