Beyond Higgs: 2 new baryons found at LHC (Introduction)

"So far, the newfound baryons behave according to QCD and to the larger “standard model” of physics, which describes all the known particles in the universe. Yet scientists know that the standard model cannot be the final word, because it does not account for dark matter—the invisible material that seems to dwarf normal matter in the cosmos. By making increasingly precise measurements of all the predictions of the standard model, researchers hope eventually to find cracks that lead the way to a larger theory to supersede it. “These two particles themselves are perfectly standard-model and expected,” Charles says, “but we're hoping that we will be able to build on these in the long run to move beyond the standard model.”
 
"The Xib particles, like all new species discovered at the LHC (including the famed Higgs boson), arose in the aftermath of collisions between speeding protons inside the accelerator's 27-kilometer underground ring. When the protons disintegrate, their mass and energy is converted into new particles. The higher a collision's energy, the more massive newly appearing particles can be. This spring the LHC will rev up again at higher energies than ever before, following a two-year hiatus for upgrades. Those higher energies should allow more and heavier particles to arise than earlier runs saw, potentially revealing exotic particles that finally push the bounds of the standard model."-http://www.scientificamerican.com/article/new-particles-found-at-large-hadron-collider/?WT.mc_id=SA_DD_20150212
