Dark matter, although of completely unknown origin, accounts for 25% of all matter in the universe, whereas regular matter inside stars and galaxies only make 5% of all matter. The rest, that is 70% of the universe is made of dark energy, as mysterious and unknown as dark matter. After half a century of research in high energy physics, we are still left with major unanswered questions such as where does the mass come from and what is this dark matter. This is why I have recently taken an interest to Hidden Valley models and Invisible Higgs decays. With the Large Hadron Collider about to turn on at CERN, near Geneva, Switzerland, along with nearly 3000 other scientists working on the ATLAS experiment, my goal is to see if you could get some clues about what matter is really made of.
