    Uncertainties in the determination of the trilinear Higgs coupling from single-Higgs observables

    by H. Bahl, P. Bechtle, J. Braathen, S. Heinemeyer, J. List, M. Vellasco, G. Weiglein

    Circular $${\text{e}}^{+} {\text{e}}^{-}$$ e + e - colliders operating at energies below the di-Higgs production threshold can provide information on the trilinear Higgs self-coupling $$\lambda _{\text {hhh}}$$ λ hhh via its loop contributions to single-Higgs production processes and electroweak precision observables. We investigate how well a non-SM value of $$\lambda _{\text {hhh}}$$ λ hhh can be determined indirectly via its loop contributions within a global EFT fit. Using an inert doublet extension of the SM Higgs sector as an example for a scenario of physics beyond the SM that could be realised in nature, we find that theoretical uncertainties related to the treatment of loop contributions and the truncation of the EFT expansion, which are usually neglected, play an important role in determining the sensitivity to $$\lambda _{\text {hhh}}$$ λ hhh in a global fit. The results obtained from such an indirect determination of $$\lambda _{\text {hhh}}$$ λ hhh without taking these additional uncertainties into account should be considered to be too optimistic, leading to an artificially high precision in the determination of $$\lambda _{\text {hhh}}$$ λ hhh . Such results could therefore be misleading in the quest to precisely identify the underlying physics of electroweak symmetry breaking.

    A modern reconstruction and analysis framework for the ILD ZHH study

    by Mikael Berggren, Bryan Bliewert, Jenny List, Dimitris Ntounis, Taikan Suehara, Junping Tian, Julie Munch Torndal, Caterina Vernieri

    Measuring the Higgs potential represents one of the main goals of the physics programs of future colliders. At center-of-mass energies of $$\sqrt{s} \ge {500\,\mathrm{\text {G}\text {eV}}}$$ s ≥ 500 G , direct access to the self-coupling $$\lambda$$ λ is enabled through the ZHH process. The ongoing update of the ILD ZHH analysis focuses on the final state $$\text {H}\text {H}\rightarrow \text {b}\bar{\text {b}}\text {b}\bar{\text {b}}$$ HH → b b ¯ b b ¯ . In our contribution, we discuss recent advancements in event reconstruction, namely, in the identification of heavy-quark jets as well as the kinematic reconstruction using corrections of semileptonic decays, kinematic fits, and observables based on matrix elements. By basing our analysis on the modern distributed pipelining system Luigi, we achieve a highly scalable, automated, and fast workflow. Composed of the full chain from event generation, fast simulation, reconstruction, and analysis, the workflow can be executed in a single step. Through columnar analysis, the event selection is greatly accelerated. We can process $$\mathcal {O}(10^8)$$ O ( 10 8 ) events in a few hours with $$\mathcal {O}(10^3)$$ O ( 10 3 ) available nodes.

    A dump leakage calorimeter to measure the flux of high-energy electrons and photons

    by Antonios Athanassiadis, Ties Behnke, Jonas Björklund Svensson, Oleksandr Borysov, Maryna Borysova, Lewis Boulton, Sarawit Chindaratchakul, Beate Heinemann, Louis Helary, Ruth Jacobs, et al.

    We developed a novel apparatus based on a lead-glass calorimeter that can measure the flux of high-energy electrons or photons. Our detector uses the electromagnetic shower leakage from the beam dump, where the particles are disposed of at the beamline's end. A prototype of such a calorimeter was set up at the FLASHForward experiment at DESY. We show that it can measure the electron bunch charge with a typical precision on the order of 10% and an accuracy at the few-percent level. Additionally, it is capable of determining the beam's position with a precision on the order of tens of micrometers. Finally, we demonstrate applicability to high-energy photons.

    A linear collider vision for the future of particle physics

    by H. Abramowicz, E. Adli, F. Alharthi, M. Almanza-Soto, M. M. Altakach, W. Altmannshofer, S. Ampudia Castelazo, D. Angal-Kalinin, J. Anguiano, R. B. Appleby, et al.

    In this paper we review the physics opportunities at linear $\mathrm{e}^{+}\mathrm{e}^{-} $ e + e − colliders with a special focus on high centre-of-mass energies and beam polarisation, take a fresh look at the various accelerator technologies available or under development and, for the first time, discuss how a facility first equipped with a technology that is mature today could be upgraded with technologies of tomorrow to reach much higher energies and/or luminosities. In addition, we discuss detectors, alternative collider modes, as well as opportunities for beyond-collider experiments and R&D facilities as part of a linear collider facility (LCF). The material of this paper supports all plans for $\mathrm{e}^{+}\mathrm{e}^{-} $ e + e − linear colliders and the additional opportunities they offer, independently of technology choice or proposed site, as well as R&D for advanced accelerator technologies. This joint perspective on the physics goals, early technologies and upgrade strategies has been developed by the LCVision team based on an initial discussion at LCWS2024 in Tokyo and a follow-up at the LCVision Community Event at CERN in January 2025. It heavily builds on decades of achievements of the global linear collider community, in particular in the context of CLIC and ILC.

    Assessing uncertainties in the determination of the trilinear Higgs self-coupling from single-Higgs observables

    by Murillo Rebuzzi Ardións Vellasco, Henning Bahl, Philip Bechtle, Johannes Braathen, Sven Heinemeyer, Jenny List, Georg Ralf Weiglein

    Circular $e^{+}e^{-}$ colliders operating at energies below the di-Higgs production threshold can provide information on the trilinear Higgs self-coupling $\lambda_{hhh}$ via its loop contributions to single Higgs production processes and electroweak precision observables. We investigate how well a non-SM value of $\lambda_{hhh}$ can be determined indirectly via its loop contributions within a global EFT fit. Using an inert doublet extension of the SM Higgs sector as an example for a scenario of physics beyond the SM that could be realised in nature, we find that theoretical uncertainties related to the treatment of loop contributions and the truncation of the EFT expansion, which are usually neglected, play an important role in determining the sensitivity to $\lambda_{hhh}$ in a global fit. The results obtained from such an indirect determination of $\lambda_{hhh}$ without taking these additional uncertainties into account would be too optimistic, leading to an artificially high resulting precision for $\lambda_{hhh}$. They could therefore be misleading in the quest to precisely identify the underlying physics of electroweak symmetry breaking.

    A High-Flux Electron Detector System to Measure Non-linear Compton Scattering at LUXE

    by Antonios Athanassiadis, Robert Ariniello, Louis Helary, Luke Hendriks, Ruth Jacobs, Alexander Knetsch, Jenny List, Sebastian Meuren, Gudrid Moortgat-Pick, Ivan Rajkovic, et al.

    Recently, advancements in high-intensity laser technology have enabled the exploration of non-perturbative Quantum Electrodynamics (QED) in strong-field regimes. Notable aspects include non-linear Compton scattering and Breit-Wheeler pair production, observable when colliding high-intensity laser pulses and relativistic electron beams. The LUXE experiment at DESY and the E-320 experiment at SLAC aim to study these phenomena by measuring the created high-flux Compton electrons and photons. We propose a novel detector system featuring a segmented gas-filled Cherenkov detector with a scintillator screen and camera setup, designed to efficiently detect high-flux Compton electrons. Preliminary results from E-320 measurement campaigns demonstrate methods for reconstructing electron energy spectra, aiming to reveal crucial features of non-perturbative QED.

    Science4Peace: A Plea for Continued Peaceful International Scientific Cooperation (Input to the European Strategy for Particle Physics -- 2026 update)

    by A. Ali, M. Barone, D. Britzger, A. Cooper-Sarkar, J. Ellis, S. Franchoo, A. Giammanco, A. Glazov, H. Jung, D. Käfer, et al.

    The European Strategy for Particle Physics (ESPP) - 2026 update is taking place in a turbulent international climate. Many of the norms that have governed relations between states for decades are being broken or challenged. The future progress of science in general, and particle physics in particular, will depend on our ability to maintain peaceful international scientific collaboration in the face of political pressures. We plead that the ESPP 2026 update acknowledge explicitly the importance of peaceful international scientific collaboration, not only for the progress of science, but also as a precious bridge between geopolitical blocs.

    Physics case for an e+e− collider at 500 GeV and above

    by Philip Bechtle, Sven Heinemeyer, Jenny List, Gudrid Moortgat-Pick, Georg Weiglein

    Some highlights of the physics case for running an e+e− collider at 500 GeV and above are discussed with a particular emphasis on the experimental access to the Higgs potential via di-Higgs and (at sufficiently high energy) triple Higgs production. The information obtainable from Higgs pair production at about 500 GeV is compared with the prospects for the HL-LHC and with the indirect information that can be obtained from a Higgs factory running at lower energies.
