B3.00001: Precision lattice QCD: challenges and prospects Invited Speaker: Shoji Hashimoto With Peta-flops scale computational resources, lattice QCD simulation has recently reached one of its primary goals, i.e. reproducing the low-lying hadron spectrum starting from the QCD Lagrangian. Applications to various other phenomenological quantities, for which no other way of precise theoretical calculation is available, would become the next milestone. In this talk I will provide a brief overview of the field and summarize the remaining problems to be solved before achieving the precision calculations. [Preview Abstract] |

B3.00002: Nonperturbative QCD corrections to the muon g-2 Invited Speaker: Dru Renner The value of the anomalous magnetic moment of the muon measured at Brookhaven National Lab disagrees with that predicted by the Standard Model by more than three standard deviations. This raises the prospects of discovering physics beyond the Standard Model if this discrepancy can be substantially verified. The uncertainty on the Standard Model result is dominated by hadronic corrections. The leading correction is currently estimated by a dispersive analysis of experimental measurements, but recent results have demonstrated that a fully theoretical and nonperturbative determination of this contribution can be obtained using the methods of lattice QCD. I will review the latest lattice calculations and discuss the prospects for a precise determination of the leading QCD correction to the muon g-2. [Preview Abstract] |

B3.00003: Lattice QCD calculation of $K\to\pi\pi$ decays Invited Speaker: Thomas Blum Recent lattice QCD calculations of $K\to\pi\pi$ decays by the RBC/UKQCD collaboration are described, including $\Delta I=3/2$ transitions at physical kinematics and $\Delta I = 1/2$ transitions at threshold. New techniques for the latter and calculations in-progress at physical quark masses are presented. Prospects for a complete calculation of the $\Delta I = 1/2$ rule and direct CP violation in K decays ($\epsilon^\prime$) are discussed. [Preview Abstract] |
