FP420 is an R&D collaboration for developing very forward proton detectors at the LHC, for the CMS experiment in particular. It involves not only building state-of-the-art detectors but also studies of novel and unique ways of detecting new physics, in particular by tagging high-energy photon interactions.

High energy photon induced interactions at the LHC

High-energy photon-photon and photon-proton interactions at the LHC offer interesting possibilities for the study of the electroweak sector up to TeV scale and the search for processes beyond the Standard Model. After in-depth exploratory studies, we performed using the CMS data first measurement of two-photon muon pair production as well as first ever observation of W boson pairs produced by photon fusion. Now our group is leading unique investigations of quartic couplings between photons and W and Z bosons.

External collaborators: CMS FSQ analysis group and the group of A. Szczurek (Krakow).
