Goals for the session :
a) Theory: Current SM predictions for R(D) and R(Dstar) and their uncertainties: Principal areas of improvement and potential external input (theory or experiment) that could have in significant impact.
b) Experiments: Review of the current ratio measurements, and prospects for new results in the near future. Address dominant systematic uncertainties, both common to all measurements and those specific to final states for signal, backgrounds and normalization. Planned improvements to selection and simulation of signal and backgrounds, and inclusion of other tau and D (and Dstar for Belle) decay modes. Expected reduction in statistical and systematic uncertainties.
Goals for the session:
a) Theory : Status of current understanding and potential improvements of the precision of s.l. decay B decays involving D and Dstar and higher mass charm mesons, their masses and spins, and momentum and angular contributions.
b) Experiments: Status of the current understanding of decay s.l. B decays for D and Dstar and higher mass charm mesons, which feed down to the ground states. Additional measurements of production rates and distributions, masses, spins, meson decays, s.l. BF and FF, suitable control samples to check simulations.
Goals for the session
a) Theory: What could we learn from such measurements? Current and future improved predictions of central values and sources of major theoretical uncertainties for other ratios R. What are suitable normalization channels to reduce theoretical uncertainties.
b) Experiments: Plans for measurements of other ratios. Which are unique to LHCb? What are the best suited normalization channels and control samples. What are expected statistical and dominant systematic uncertainties? What will be the additional information needed to establish signal and principal background contributions?
Goals for the session
a) Theory: List all ancillary theoretical and experimental work that would help sharpen the SM prediction for various ratios R.
b) Experiments: Status and prospects for additional measurements required for B and D meson decays necessary to improve the precision of R measurements: i.e. the projected systematic uncertainties for signal, normalization, and backgrounds, and control samples for efficiency studies and improvements of simulations.
Goals for the session:
Theory: Overview of potential non-SM processes that might contribute to semitauonic B decays. Proposals for discriminating variables, like tau and D(*) momenta, angular distributions and polarization, that are less sensitive to theoretical uncertainties.
Experiments: Current and future methods to distinguish contributions from potential non-SM processes form SM ones, based on differential distributions for specific models or model independent approaches.
Goals for the session
Theory: General framework to parametrize non-SM contributions and possibly the development of parameter dependent predictions for measured quantities, ratios and differential distributions. Potential of various models to incorporate LFV signatures in flavor changing neutral current processes, like b →s transitions.
Experiments: New approaches?! Related processes? development of Hammer and other programs useful for extracting non-SM signatures.
Conclusion from theory and experimental point of view. next steps, next meetings, etc...
