GasToF: ultra fast timing detector
GasToF (Gas Time-of-Flight) detector is a Cherenkov detector developed for very precise (with <10 ps resolution) flight time measurements of very forward protons at the LHC. Such an excellent time resolution allows, using z-by-timing technique, for precise measurements of the event vertex z-coordinate and the background reduction. Such a detector is essential for selecting exclusive and semi-exclusive processes at high luminosity, and can also be applied for the timing and particle ID at future experiments.

High energy photon-induced interactions
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, first measurements of two-photon muon pair production were performed as well as first ever observation of W boson pairs produced by photon fusion. Now unique investigations of quartic couplings between photons and W and Z bosons are being pursued.
