    Andrew Cheek (TDLI, SJTU)

    In this talk I will discuss recent changes in the allowed parameter space for the $U(1)_{L_\mu-L_\tau}$ extension to the Standard Model. I will argue that despite the (g-2)$_μ$ anomaly disappearing, this model still holds a lot of potential, in particular as a portal to dark matter. This provides vital motivation for a future muon collider. Furthermore, I will present ongoing work with the...

  39. 45. Electroweak baryogenesis from charged current anomalies in $B$ meson decays
    Dr CRISTIAN FELIPE SIERRA FONSECA (Nanjing Normal University)

    We demonstrate for the first time that new physics explaining the long standing charged $B$ meson anomalies, $R(D^{(*)})$, can be the source of CP violation that explains the observed baryon asymmetry of the universe (BAU). We consider the general two Higgs doublet model with complex Yukawa couplings and compute the BAU in the semiclassical formalism, using a novel analytic approximation for...

  40. 8. Entanglement and Bell Nonlocality in τ+τ- at the LHC using Machine Learning for Neutrino Reconstruction
    Baihong Zhou (TDLI, SJTU)

    Experiments at the CERN Large Hadron Collider (LHC) have accumulated an unprecedented amount of data corresponding to a large variety of quantum states. Although searching for new particles beyond the Standard Model of particle physics remains a high priority for the LHC program, precision measurements of the physical processes predicted in the Standard Model continue to lead us to a deeper...

  41. 40. EW Vacuum Decay Induced by Domain Walls in the N2HDM
    Mohamed Younes Sassi (University of Hamburg)

    The Next-to-Two-Higgs-Doublet model (N2HDM) has a rich vacuum structure where multiple electroweak (EW) breaking minima, as well as CP and electric-charge breaking minima, can coexist. These minima can be deeper than the electroweak vacuum $v_{ew} \approx 246$ GeV of our universe, making our vacuum metastable. In such a case, one needs to calculate the tunneling rate from the EW vacuum to the...

  42. 4. Frontiers of Analytic Multi-loop Feynman Integrals
    Yang Zhang (University of Science and Technology of China)

    With the development on canonical differential equation, integral basis with uniformal transcendental weights, computational algebraic geometry method, the era of analytic computations of multi-loop multi-leg multi-scale Feynman integrals is coming. We analytically computed all 2loop 6point planar massless Feynman integrals. This is a mile stone of analytic feynman integral computation. The...

  45. 35. Loop-level lepton flavor violation in the left-right symmetric model
    Yongchao Zhang (Southeast University)

    The left-right symmetric model (LRSM) is a well-motived scenario to accommodate the tiny neutrino masses, e.g. via the type-I seesaw. The mixing of heavy neutrinos in the LRSM could induce lepton flavor violating (LFV) couplings of the $SU(2)_R$-breaking neutral scalar $H_3$, which arise at the 1-loop level via the heavy $W_R$ boson and the heavy neutrinos. When $H_3$ is light, say at or below...

  46. 39. NNLO mixed QCD-EW corrections to W-pair production at electron-positron colliders
    Zhe Li

    The discrepancy between the CDF measurement and the Standard Model theoretical prediction for the W-boson mass underscores the importance of conducting high-precision studies on the W boson, which is one of the predominant objectives of proposed future e+e− colliders. We investigate in detail the production of W-boson pairs at e+e− colliders, and compute the next-to-next-to-leading order mixed...

  47. 37. Precise Measurement of Higgs Hadronic Decay at CEPC
    Yifan Zhu

    We conduct a detailed Monte Carlo study of the process e⁺e⁻ → ZH at the CEPC. The analysis focuses on final states where the Z boson decays invisibly, while the Higgs boson decays hadronically through H → bb̄, cc̄, gg and ss̄. To distinguish among hadronic final states, we apply advanced jet-tagging methods based on ParticleNet, Particle Transformer, and the More-Interaction Particle...

  48. 38. Precise Predictions for Semi-leptonic Heavy-to-light Decays
    Dr Long Chen (Shandong University)

    We present the first complete $\mathcal{O}(\alpha_s^2)$ and $\mathcal{O}(\alpha_s^3)$ perturbative QCD corrections to all Heavy-to-light structure functions underlying the triple-differential semi-leptonic decay rates of heavy quarks. In particular, we presented the so-far most accurate theoretical predictions for the Top and Bottom quark semi-leptonic decay widths, including the currently...

  50. 9. Probing Neutral Triple Gauge Couplings via Zy production at Future Lepton Collider
    Linjing Duan (TDLI, SJTU)

    Neutral triple gauge couplings (nTGCs) are absent in the Standard Model (SM) and at the dimension-6 level in the Standard Model Effective Field Theory (SMEFT), arising first from dimension-8 operators. As such, they provide a unique window for probing new physics beyond the SM. These dimension-8 operators can be mapped to nTGC form factors whose structure is consistent with the...
