  1. 101. Reimagining Electron-Positron Collider Luminosity Measurements

    WG1-PREC - Physics Potential: Precision

    Our recent work has shown that a novel, much higher granularity
    forward calorimetry concept can enable much more detailed and precise
    reconstruction than the baseline designs based on LEP luminometers, together
    with the capability of electron/positron/photon separation.

    This new calorimeter concept is designed primarily to maximize the acceptance
    for $e^+e^- \to \gamma \gamma$ as an...

    We classify the possible deviations from the Standard Model in the QED-dominated $\mathrm{e^+e^-}\to\gamma\gamma$ process under the assumption of a preserved $SU(2)_L \times U(1)_Y$ symmetry. We find that the only deviations really observable in practice correspond to a correction of the differential cross section by a factor $(1 + \frac{c_8~s^2}{8\pi\alpha\Lambda^4}~\sin^2\theta)$, where...

  3. 60. Probing New Physics at future e+e- colliders with two-particle angular correlations

    Long-range angular correlations between particles could reveal physics beyond the Standard Model, such as Hidden Valley (HV) scenarios. Our emphasis is on a hidden QCD-like sector, where the emergence of HV matter alongside QCD partonic cascades could amplify and extend azimuthal correlations among final-state particles.

    Our study at the detector level focuses on the detectability of these...

  4. 71. Metrology requirements for the integrated luminosity measurement at ILC
    Ivanka Bozovic-Jelisavcic (VINCA Institute of Nuclear Sciences)
    WG1-PREC - Physics Potential: Precision
    ORAL

    Precision measurement of the integrated luminosity (L) at future Higgs factories, including ILC, is of crucial importance for the cross-section measurements, and in particular for the line-shape measurements at the Z-pole. Since there is no up-to-date estimate of the integrated luminosity
    uncertainties arising from metrology effects at ILC, here we review a feasibility of the targeted...
