The Future Circular Collider (FCC) programme provides unique opportunities for comprehensive and precise studies of top quark physics. At the FCC-ee, operating at and slightly above the top pair threshold, a precise measurement of the top quark mass with a statistical and systematic accuracy down to the MeV level can be achieved through a threshold scan. Furthermore, the FCC-ee run at 365 GeV...

Next-generation high-energy colliders, including the HL-LHC, and proposed Higgs factories such as FCC-ee, ILC, and CEPC, aim to probe selected Higgs and electroweak observables at the per-mille level. Achieving the required theoretical precision demands NNLO electroweak predictions alongside high-order QCD corrections. However, complete NNLO EW calculations in the SM remain scarce, with a key...

The diphoton decay of the Higgs boson is one of the original discovery channels and remains a golden channel for probing the properties of the Higgs boson. In this talk, I will present the first complete three-loop mixed electroweak–QCD corrections to this decay channel. The corresponding phenomenological predictions will also be discussed.

The scattering of microscopic particles generically gives rise to highly structured quantum final states. A growing body of work has begun to explore whether the quantum-information characteristics of these states are merely emergent, or whether they encode deep principles of the underlying quantum field theory. Among these characteristics is magic, or non-stabilizerness, which measures the...

Higher-order contributions due to initial state radiation (ISR) in electron-positron annihilation processes are analyzed analytically and numerically. Effects due to variation of factorization scale and scheme choices in ISR are studied. A new procedure for exponentiation of higher-order next-to-leading photonic and pair corrections is suggested. The results are relevant for increasing the...

Recent analytic results on higher-order QED radiative corrections are implemented into the ZFITTER computer code. Certain corrections in the previous version of the program in $O(\alpha^2)$ and $O(\alpha^3L^3)$ orders are applied. Higher order contributions in the leading and next-to-leading logarithmic approximation are added. A new exponentiation procedure is used. Numerical results are...

ReneSANCe provides one-loop EW and higher order corrections for the processes
$e^+e^- \to HZ$, $e^+e^- \to ZZ$, $e^+e^- \to \gamma Z$ and processes used for luminosity monitoring.
We have taken the first steps to enable decays of final state unstable particles and radiative corrections in decays. All spin correlations... -

We give a report on new developments in the gamma-gamma collision mode of the ReneSANCe Monte Carlo event generator. Results for a number of polarized Standard Model processes will be presented for future gamma-gamma colliders based on ee-colliders where high energy photons are produced via Compton backscattering of laser beams.

We present a full-simulation study of longitudinal Λ polarization in strange-tagged Z → ss̄ events with the AGORA detector at CEPC. A source-dependent polarization model, based on the OPAL benchmark, is implemented directly in event generation and propagated through the CEPC AGORA detector full simulation and reconstruction. Strange-jet tagging and Λ → pπ reconstruction define an inclusive...

The Z-pole operation of CEPC will provide a large data sample for precision electroweak measurements. We present measurements of the forward-backward asymmetries $A_{FB}$ in Z decays using the CEPC reference detector simulation, and further derive the effective weak mixing angle $\sin^2\theta_W^{\mathrm{eff}}$ from these observables. The Particle Transformer deep learning architecture is...

We present the two-loop mixed strong-electroweak virtual corrections to the production of a massive bottom-antibottom quark pair in electron-positron collisions. The evaluation of all the relevant Feynman integrals, including those with up to five internal massive lines with three different mass values, has been worked out relying on semi-analytical techniques, using complex-valued masses for...
