Illustration of the possible layout of the quarks in a pentaquark particle such as those discovered at LHCb. The five quarks might be tightly bonded (left). They might also be assembled into a meson (one quark and one antiquark) and a baryon (three quarks), weakly bound together. (Courtesy: CERN)

Conventional theories predict that dark matter particles would not collide, rather they would slip past one another (above). Hochberg et al. predicts dark matter SIMPs would collide and interact with one another (below). (Credit: Kavli IPMU)

Artist's impression of dark matter distribution. Left image assumes conventional dark matter theories, where dark matter would be highly peaked in small area in galaxy center. Right image assumes SIMPs, where dark matter in galaxy would spread out from the center.

The HERA accelerator at DESY in Hamburg was unique in that it smashed two totally different kinds of particles into each other – protons and electrons or positrons. HERA thus consists of two different accelerator rings: a superconducting proton ring and a normal-conducting electron ring. HERA ran from 1990 to 2007.
