Session I: Electroweak physics

Oral presentation using Zoom

The confirmed $(g-2{)}_{\mu }$ anomaly can perfectly be fitted in the Minimal Supersymmetric Standard Model (MSSM), taking into account all experimental constraints. This requires a relatively light electroweak sector of the MSSM, which in turn can give rise to positive contributions of the $W$ boson mass, $M_W$. We analyze these predictions in view of the anticipated improved measurements of $M_W$...

Session I: Electroweak physics

Oral presentation using Zoom

We study the measurement of Higgs boson self-couplings through 2→3 vector boson scattering (VBS) processes in the framework of Standard Model effective field theory (SMEFT) at both proton and lepton colliders. The SMEFT contribution to the amplitude of the 2→3 VBS processes, taking WLWL→WLWLh and WLWL→hhh as examples, exhibits enhancement with the energy A(BSM)/A(SM)∼E^2/Λ^2, which indicates...

Session I: Electroweak physics

Oral presentation using Zoom

The International Linear Collider (ILC) is a next-generation electron-positron linear collider proposed to search for new physics beyond the Standard Model.
In the ILC, the International Large Detector (ILD) has been proposed as a detector for the precise measurement of final state particles. Collision of electron and positron generates tau lepton pair in ILC experiment. This process can be...

112. Status of the MUonE experiment

Session I: Electroweak physics

Oral presentation using Zoom

The MUonE experiment aims at a competitive determination of the leading hadronic contribution to the muon anomalous magnetic moment, completely independent from the other existing results.
It could have a crucial role to clarify the comparison of the $a_{\mu }$ measurement with the Standard Model, given the recent Fermilab result, and the tension between the accepted theory prediction and a new...

126. Center-of-mass energy determination using dimuon events at ILC

Graham Wilson

Session I: Electroweak physics

Oral presentation using Zoom

Precision measurements of masses from both center-of-mass energy scans and using beam energy and momentum constraints rely on knowledge of the absolute center-of-mass energy scale and the luminosity spectrum, dL/d$\sqrt{s}$. A key method is the ${\sqrt{s}}_p$ technique that uses the tracker muon momenta measurements in $e^{+}{e}^{-}\to {\mu }^{+}{\mu }^{-}(\gamma )$ events to determine both...
