Article Synopsis
- - The HHH Workshop held in Dubrovnik in July 2023 focused on advancing the understanding of the Higgs boson and its properties within the Standard Model (SM).
- - To confirm or challenge the SM, researchers need to measure the full potential of the Higgs, including the triple and quartic scalar couplings, particularly involving three scalar bosons at around 125 GeV.
- - The report highlights ongoing experimental efforts and theoretical models aimed at improving measurement rates and addressing challenges related to multi-scalar final states.
Rare top quark decays at a 100 TeV proton-proton collider: and .

March 2018
We investigate extremely rare top quark decays at a future proton-proton collider with centre-of-mass energy of 100 TeV. We focus on two decay modes: radiative decay with a boson, , and flavour-changing neutral decay with a Higgs boson, , the former being kinematically suppressed with a branching ratio of (Altarelli et al., Phys Lett B 502:125-132, 2001), and the latter highly loop-suppressed, with a branching ratio of (Aguilar-Saavedra, Acta Phys Polon B 35:2695-2710, 2004).
