LHC/ATLAS: A unique observation of particle pair creation in photon-photon collisions
Cracow, 18 February 2021
Creation of matter in an interaction of two photons belongs to a class of very rare phenomena. From the data of the ATLAS experiment at the LHC, collected with the new AFP proton detectors at the highest energies available to-date, a more accurate - and more interesting - picture of the phenomena occurring during photon collisions is emerging.
If you point a glowing flashlight towards another one, you do not expect any spectacular phenomena. The photons emitted by both flashlights simply pass by each other. However, in certain collisions involving high-energy protons the situation is different. The ...
