  1. 90. Precision Measurement of the Two-Pion Contribution to the Hadronic Vacuum Polarization with KLOE

    The KLOE detector at the DA$\Phi$NE electron–positron collider has delivered some of the most precise measurements of the two-pion contribution to the hadronic vacuum polarization (HVP) term in the Standard Model prediction of the muon anomalous magnetic moment, $a_{\mu}$. A precise determination of the HVP term is essential to clarify the longstanding tension between the theoretical...

  2. 81. Differential cross-section measurement of $t\bar{t}t\bar{t}$ production with ATLAS using 2022-2024 data

    Parallel talk

    The production of four top quarks ($t\bar{t}t\bar{t}$) was observed by the ATLAS and CMS experiments in 2023 and the cross section was measured to be slightly higher than the prediction from the Standard Model. This is an important process as it has sesntivity to the top quark yukawa coupling and new physics signals. Since the start of the LHC Run-3 in 2022 and until the end of 2024, the ATLAS...

  3. 41. The MUonE Experiment and First Results from the 2025 Test run

    Precision and Anomalies
    Parallel talk

    The MUonE experiment at CERN aims to determine the leading-order hadronic vacuum polarization contribution to the Standard Model prediction of the muon anomalous magnetic moment $a_{µ}$, which plays a central role in the present differences among theoretical determinations and in the comparison with experimental measurements. MUonE follows an innovative approach based on a precise measurement...

  4. 89. Analysis of the CP Structure of the Tau Lepton Yukawa Coupling at the CMS Experiment

    Precision and Anomalies
    Parallel talk

    Despite the many successes of the Standard Model (SM), it is known to be incomplete, for instance, it does not provide an explanation for the observed baryon asymmetry of the universe. One of the necessary conditions to generate this asymmetry is charge-parity (CP) violation on a scale many orders of magnitude larger than SM predictions. An intriguing possibility is new sources of CP violation...

  5. 63. Towards Precise Determination of the CKM angle $\gamma$
    Marcelo Bovill (University of Oxford)

    Precision and Anomalies
    Parallel talk

    Precision measurements of the CKM angle $\gamma$ provide a theoretically clean test of the unitarity of the CKM matrix and are therefore a powerful probe for physics beyond the Standard Model. Despite significant experimental progress, $\gamma$ remains one of the least precisely determined CKM parameters, with current measurements dominated by statistical uncertainties. This makes $\gamma$...
