Projects such as ATLAS and CMS seek to find it, which based on electroweak observables, is expected to have an upper boundary mass of 219 GeV. This energy is within the range of energies generated by CERNs Large Hadron Collider when it becomes operational in 2007. The standard model, however, predicts its mass to lie between 130 and 190 GeV, which allows it to function on energy scales up to the Planck scale. As a scalar boson, it obeys Bose-Einstein statistics and has zero spin. This is, for 10 points, which particle first postulated in 1960s that is the quantum of the field that gives all particles mass.
