Research statement
Studying high-energy photon interactions at hadron colliders. In particular, interested by exclusive two-photon production of pairs of heavy charged particles at the LHC. Working on novel tests of the gauge boson sector of the Standard Model and searches of physics beyond the SM.
Working on photo-production tagging techniques, using very forward, near beam detectors at colliders. In particular, developing novel, ultra-fast Cerenkov detectors with picosecond resolution. Investigating possibility of new techques in ToF-PET. Has deep expertise in precise luminosity measurements at hadron colliders using QED processes.
Participating in the development of the next generation detectors of gravitational waves. Investigating physics with the proposed detectors - the Einstein Telescope and LISA.

E-TEST - Cryogenic inertial sensor development
Giacomo Bruno, Joris van Heijningen
On Feb 1, 2020 the R&D EU Interreg project E-TEST officially started. It involves 11 institutes from Belgium, Germany and Netherlands and will carry on crucial detector developments for the Einstein Telescope (ET) - a 3rd generation antenna of gravitational waves, related mostly to cryogenic operations of large mass mirrors and their suspensions, ultra-precise metrology and sensing, as well as to advanced geological studies in the region (the ET is a deep-underground detector). The CP3 group is a partner in this project and is working on work package 1 : "Ultra-cold vibration control" and in particular on a cryogenic superconducting inertial sensor.
Gravitational wave signals below a frequency of about 10 Hz are obscured by thermal noise in current detectors. Because temperature is the vibration of atoms in some respect, making the distance measurement between the mirror surfaces more challenging, the mirrors of future detectors will need to be cooled down to temperatures around 10 K. We need to control the motion of some of the cold objects, for which we develop inertial sensors that can survive this harsh environment.
CP3 members collaborate mostly with RWTH Aachen (they are preparing a cryostat where we will test the sensor), KUL (we are collaborating to develop cryogenic readout electronics for the sensor) and ULiège (we align our sensor efforts).
External collaborators: C. Collette (Liege), S. Hild (Maastricht), A. Bertolini (Nikhef), A. Gatto (KULeuven) and E-TEST collaboration.

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.
Investigate new techniques for ToF-PET.

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.
