Close-up of the U.S.-built HL-LHC magnet with signatures and a U.S. flag. Cover image for the 2023 P5 Report. An illustration of a blue and purple light coming out of a black hole. Two light beams are jutting out from the center toward the edges of the frame. The beam on the left is filled with moving blue orbs and the beam on the right is filled with two larger orbs containing small galaxy depictions. Looped GIF of wire winding. Composite image of a film strip along the top of the frame. A sun flare occupies the top left side with various bubbles floating throughout the image. A black and white microscopy image of the material; it looks like zoomed in scratches on a hard surface on the left, then the same image in vivid multicolor on the right. Rare isotopes implanted into the center of a sensitive detector known as the FRIB Decay Station initiator. Looking into the HERA tunnel, the world's most powerful electron-proton collider. Diagram showing a high-energy electron scattering from a correlated nucleon in the mirror nuclei tritium (left) and helium-3 (right). Members of science team lined-up in a water tank after the outer detector installation. Collection of three side-by-side headshots Photomultiplier tubes, designed to pick up faint light signals from particle interactions, line the inside of a detector for the Daya Bay Reactor Neutrino experiment. CUORE scientists Dr. Paolo Gorla (LNGS, left) and Dr. Lucia Canonica (MIT, right) inspect the CUORE cryogenic systems.
