Belle II Theory Interface Platform (B2TIP)


Overview

The "Belle II-Theory Interface Platform" is a joint theory-experiment effort to study the potential impacts of the Belle II program.


We plan to organise meetings twice a year gathering theory experts and Belle II members, starting

A series of workshops was run from June 2014

until the end of 2016.
One of the expected outcomes of the project is a "KEK Green Report", summarising all the important observables which will

culminating as the B2TiP / Belle II Physics Book, summarising many important observables to be measured at Belle II, their experimentally achievable precision and their impact on our understanding of the theory (Standard Model and New Physics).

This report should also include a "milestones table" clarifying the targets for the first 5 to 10 ab-1 of data as well as for the final goal at 50 ab-1.B2TiP minutes/proceedings ( invenio )

This project is an official activity of Belle II, approved by the executive board of the Belle II Collaboration in February 2014.


Workshop Dates

The 2014 meetings will be held at KEK in June and November, as a satellite meeting of the Belle and Belle II General meetings. There is a possibility of holding one workshop in 2015 at an external location. Individual working groups may choose to hold additional meetings. Please register for the meetings on the linked indico pages.

    • Relation to measurements from other experiments (e.g. LHC, neutrino, dark matter, future experiments)

    Working group mandate:

    • organise the Workshops programs, together with the co-conveners,
    • edit the corresponding sections of the KEK report,
    • take responsibility for their section of the golden mode chart (split according to experiment, theory and lattice)
    • distribute the tasks among group members,
    • contact the other working group theory conveners for the common issues,
    • contribute to the New Physics WG
    • Lattice coordinators (in Blue) are also membesr of the "lattice QCD board". The mandate of the lattice QCD board is to collect the requests and questions from the WGs concerning the potential and perspectives of lattice computations for quantities that are not covered by the other coordinators (including those that may not have been computed before). T. Kaneko (the lattice board secretary) will organize meetings with the lattice coordinators whenever necessary.

    Mailing Lists

    To be included in the general mailing list, (i) contact Phillip Urquijo if you are not a Belle II member, or (ii) subscribe to the list in Sympa if you are a Belle II member.
