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...
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...
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...
