The Physics of the Dark Photon

Marco Fabbrichesi works in high-energy theoretical physics. After graduating from the University of Virginia (USA), he has been a fellow at the JINR in Dubna (Russia), the Niels Bohr Institute in Copenhagen (Denmark) and the Theory Division at CERN in Geneva (Switzerland). Currently, he is a researcher of the Italian National Institute of Nuclear Physics in Trieste. He has published more than 90 papers spanning from string theory, supersymmetry and dark matter physics to flavor physics, CP violation in the Kaon system and the hierarchy problem in the standard model. Emidio Gabrielli works in high energy theoretical physics. After graduating in Physics at the University of Rome - Sapienza, in 1986, he received his PhD degree there in 1991. He is currently Associate Professor of Physics at the University of Trieste. Since 2012 he is also member of the CMS collaboration. He has held Senior Researcher positions at the Helsinki Institute of Physics (Finland 2000-2006) and NICPB Tallinn (Estonia 2011-2014), postdoc positions at the Theory Division of CERN, University of Notre-Dame Indiana (US), University Autonoma of Madrid (Spain). He has published more than 80 papers in peer-reviewed journals, spanning from standard model, supersymmetry, dark matter, flavor physics, quantum gravity, lattice and quantum field theory. He has one renowned paper on supersymmetry with more than 1000 citations. Gaia Lanfranchi is a senior research scientist of the Laboratori Nazionali di Frascati (LNF) of INFN, currently based at CERN, working in experimental High Energy Physics. She has been a renowned expert of flavor physics and then moved her interest towards the physics of the dark sector. After graduating and obtaining her PhD at the University of Rome - Sapienza, in 1997, she joined the HEP experimental physics groups at LNF to work in KLOE (1997-2008), LHCb (2002-today), NA62 (2016-today), and SHiP (2014-today) experiments. She has held several leading positions and appointments in international advisory panels and committees. She serves as reviewer for several high-impact international journals and as referee for the Netherlands Organization for Scientific Research, Swiss National Science Foundation, and UK-STFC. She has authored more than 750 papers in peer-reviewed international journals.
