  1. 35. Rare b decays meet high-mass Drell-Yan

    Invited talk

    Rare b hadron decays are considered excellent probes of new semileptonic four-fermion interactions of microscopic origin. However, the same interactions also correct the high-mass Drell-Yan tails. In this work, we revisit the first statement in the context
    of this complementarity and chart the space of short-distance new physics that could show up in rare b decays. We analyze the latest b →...

  2. 5. Probing light quark Yukawa couplings at the (HL-)LHC

    Invited talk

    Light quark Yukawa couplings are notoriously difficult to measure: the HL-LHC will be able to constrain the first generation couplings only by a factor of few hundred times their SM value.
    I will discuss Higgs pair production and the Higgs off-shell measurement as potential probes of light quark Yukawa couplings. For the Higgs pair production process I will discuss also how interpretable...

  3. 49. Probing Flavor in semileptonic transitions at High-$p_T$

    Invited talk

    The Drell-Yan processes $pp\to\ell\nu$ and $pp\to\ell\ell$ at high transverse momentum can provide important probes of semileptonic transitions that are complementary to low-energy flavor physics observables. We parametrize possible New Physics (NP) contributions to these processes in terms of form-factors, and derive the corresponding bounds by recasting the latest ATLAS and CMS run 2...

  4. 21. Exploring High-Energy Physics at the LHC: Recent Results and Future Prospects from ATLAS and CMS

    Invited talk

    The Large Hadron Collider (LHC) at CERN has enabled us to explore the frontiers of particle physics and understand the fundamental nature of the universe. In this talk, I will present a comprehensive overview of high pT physics analyses conducted in Run 2 of the LHC by both the ATLAS and CMS experiments. These analyses cover a broad range of topics, including measurements of the Higgs boson,...

  5. 42. Z′-mediated Majorana dark matter: suppressed direct-detection rate and complementarity of LHC searches

    Invited talk

    We study the direct-detection rate for axial-vectorial dark matter scattering off nuclei in an SU(2) × U(1) invariant effective theory and compare it against the LHC reach. Current constraints from direct detection experiments are already bounding the mediator mass to be well into the TeV range for WIMP-like scenarios. This motivates a consistent and systematic exploration of the parameter...

  6. 9. Left-Right Symmetry at FCC
    Prof. Fabrizio Nesti
    BSM and Precision Physics
    Invited talk

    Left-Right symmetry faces stringent constraints from flavor and direct searches, that motivate its scale to be in the tens of TeV regime. I will thus describe and review the prospects for probing this restoration of Parity at future hadron colliders.
