    Higgs production in association with a photon at hadron colliders is a rare process, not yet observed at the LHC. We show that this process is sensitive to significant deviations of Higgs couplings to first and second generation SM quarks (particularly the up-type) from their SM values, and use a multivariate neural network analysis to derive the prospects of the High Luminosity LHC to probe...

    I present new results for fully differential next-to-next-to-leading-order corrections to Higgs boson production in vector-boson fusion in the factorizing limit. In addition to previous computations the fully differential decay of the Higgs boson at leading order is included.

    The bbγγ channel is one of the most sensitive HH final states for measuring the Higgs self-coupling and di-Higgs production cross-section. This analysis capitalizes on the clean signature of the two photons in the final state combined with the high branching ratio of H→bb. This talk will present the latest non-resonant ATLAS HH→ bbγγ results with the full Run 2 dataset of 139/fb at 13 TeV. The...

    Muon collisions at multi-TeV center of mass energies are ideal for studying Higgs boson properties. At these energies the production rates will allow precise measurements of its couplings to fermions and bosons. In addition the double Higgs boson production rate could be sufficiently high to directly measure the parameters of trilinear self-couplings, giving access to the determination of the...

    LHCb is a spectrometer that covers the forward region of proton-proton collisions.
    Thanks to its excellent vertex reconstruction system, it has already demonstrated its capability to identify heavy flavour jets. Moreover, the c-jet identification (c-tagging) is a crucial ingredient for the search of H->cc at LHCb. In this talk, the c-tagging algorithm used at LHCb will be illustrated, as...

    A crucial element of the study of the Higgs boson is the measurement of its couplings to the fermions of the second generation. Experiments at the Large Hadron Collider (LHC) have recently reported the first evidence for the Higgs boson coupling to the muon. It is equally important to measure the Higgs boson coupling to the charm and strange quarks. These decay modes are nearly impossible to...

    The coupling of the Higgs boson to tau leptons is one of the most precise measured couplings of the Higgs boson to fermions. A measurement of the production cross sections of the Higgs boson into two tau leptons is presented. The cross section is measured in the gluon-fusion, vector-boson-fusion, boson associated, and top-quark pair associated production channels. The result is shown in the...
