        Flash talk: Collins-Soper kernel from lattice QCD at the physical pion mass 10m

        Collins-Soper (CS) evolution kernel is necessary to relate transverse-momentum-dependent parton distribution functions (TMDPDFs) at different scales. The kernel's behavior at high as well as low transverse momenta $q_T$ may lead to sizable variations in the uncertainty estimates for $m_W$. For $q_T \sim \Lambda_\mathrm{QCD}$, the CS kernel is non-perturbative; the determination of the CS kernel in the non-perturbative regime can only be done through experiment or first-principles calculations. Here, preliminary results are presented for a new calculation of the non-perturbative CS kernel using lattice QCD and Large-Momentum Effective Theory. This work improves the control over and reduces the systematic uncertainties compared to previous lattice QCD calculations, and is the first computation at close-to-physical valence and sea pion masses 𝑚𝜋≈140 MeV.

      Theory Keynote Talk (Special CTP Seminar): The W-boson Mass Puzzle: Examining the Interplay Between Theory and Experiment 1h Kolker Room (26-414)

      Kolker Room (26-414)

      Massachusetts Institute of Technology, Cambridge, MA, USA

      Recently, the Tevatron CDF collaboration reported a highly precise
      measurement of the W-boson mass with an uncertainty of 0.1 per-mille.
      This measurement is in significant tension with Standard Model global
      fits and earlier measurements. The W-boson mass is an input parameter in
      the Standard Model, and its determination relies heavily on theory
      predictions. However, these predictions have uncertainties that are
      orders of magnitude larger, which raises the question in how far theory
      uncertainties enter the measurement and translate into W-mass
      uncertainties. In this talk, we discuss the challenges in accurate
      theory predictions and their impact on the W-boson mass measurements. We
      explore the significance of the tension between the CDF measurement and
      previous results, and discuss potential avenues for improving theory
      predictions in future measurements.
