    There is broad agreement that the next major collider should include an e⁺e⁻ Higgs factory mode. Yet, given the remarkable progress expected from the HL-LHC, I argue that a program focusing too heavily on Higgs coupling measurements is not ambitious enough, be it linear or circular. The critical question is what additional capabilities each design offers. Circular machines provide unparalleled...

Focusing on the $Z'$ production with a radiated photon, we show that the FCC-ee can significantly extend the unprobed parameter space by increasing the exclusion in the coupling by one to two orders of magnitude in the kinematically allowed mass range...

    Accurate, fully differential predictions are essential for precise experimental analyses at linear colliders, and are typically delivered by parton-shower Monte Carlo programs. Last year, the event generator Sherpa has been released in a new version (3.0), with an emphasis on incorporating higher-order electroweak and QCD effects. We will summarise its new features, particularly those relevant...

    We hypothesize that third- and higher-order treatment of particle optics have a minor impact on the beam size at the interaction point (IP)
    and on the resulting luminosity, compared to linear and second-order contributions.
    To test this, we are conducting a comprehensive simulation campaign using PLACET, GuineaPig, and MAPCLASS to quantify the correlation
    between IP beam size and luminosity...

    Recently, a high energy superconducting (SC) e+e− linear collider with energy recovery (ERLC) has been proposed, which uses twin RF structures to avoid parasitic collisions inside linacs. Such a collider can operate in a duty cycle (DC) or continuous (CW) modes (if sufficient power is available) with a luminosity of about 10^36) cm^−2 s^−1 at 2E_0 = 250−500 GeV. In this presentation I will...

    Future electron–positron Higgs/Top/Electroweak factories will require Monte Carlo event generation at the same level of precision as the experimental measurements. Since several generators can provide predictions of comparable accuracy, it is essential to compare them consistently to identify deviations and evaluate systematic uncertainties arising from the event generation stage.
    We give an...

    As interest in advanced acceleration techniques for future high-energy colliders continues to grow, there is increasing demand for Beam Delivery Systems (BDS) capable of transporting beams with energies beyond the CLIC design. While plasma-based collider concepts offer the potential for significantly reduced accelerator footprints, the BDS is expected to dominate the overall facility length at...

    The Ghost Collider is an innovative proposal for a 550 GeV center-of-mass, 275 GeV per beam linear collider with four interaction regions, each with the design luminosity. The primary innovation is the use of “ghost bunches” containing equal numbers of electrons and positrons so they are electrically neutral. In the linacs, energy is transferred between electrons and positrons in the same...
