Current and Future Status of the First-Row CKM Unitarity

Tests of the unitarity constraint on the first row of the CKM matrix continue to provide powerful probe of physics beyond the Standard Model. The effectiveness of this probe relies on having sufficiently precise measurements and theoretical, Standard Model computations. This workshop will address the following questions: What is the status of the first-row CKM unitarity constraint? What is the status of radiative and nuclear/hadronic structure-dependent corrections that underly that test? A particular focus will be on arriving at a clear picture of the present level of theoretical uncertainty in extracting the value of V_ud from experiment and on strategies to reduce it. An additional emphasis will fall on obtaining a consensus for present determination of V_us. We will gather the world experts for providing a complete and in-depth review of all crucial theoretical and experimental ingredients.
