This observation marks a significant milestone in understanding hard diffraction and strong interaction dynamics at the LHC, specifically by isolating intact protons amidst high pileup conditions. By successfully detecting W and Z bosons alongside surviving protons, researchers have revitalized studies into exchange mechanisms that connect modern collider data to foundational theoretical frameworks from the 1960s. The achievement demonstrates the precision of the Precision Proton Spectrometer in probing quantum chromodynamics under extreme collision energies.
CMS sees intact protons after LHC collisions, reviving old physics

At the LHC, CMS detected W and Z bosons alongside protons surviving collisions, reviving “diffractive physics” studies.
For the first time at the Large Hadron Collider, researchers with the CMS experiment have observed W and Z bosons and TeV-scale jets alongside a proton surviving a collision intact, reviving a previously obscured area of study. This observation overcomes a significant technical hurdle, high pileup, allowing exploration of hard diffraction, a phenomenon where high-energy collisions leave one proton unscathed. Before quantum…
