The goals of the ILD physics working group are
- to make compelling physics case for ILC that can convince decision makers that ILC is worth the investment, and
- to optimize the ILD detector design so as to realize (1).
To achieve these goals, the ILD physics working group has a coordination team. The roles of the physics coordination team is to make a task list and set milestones and timeline, organize (currently three) subgroups and collaborate with other parts of ILD (for detector optimization in particular) as well as with the LCC physics working group, monitor and, if needed, guide and/or help progress of each subgroup, communicate the achievements to appropriate targets as needed, thereby positively influencing decision makers, while contributing to international and regional strategy discussions.
The structure and the current members of the coordination team of the ILD physics working group are shown below:
There are some gray zones between the three subgroups. For the overlaps, we tentatively draw the boundaries in the following way:
- Higgs CP from ttH primarily belongs to Higgs/EW, but keeps close with Top/QCD
- e+e- -> bb belongs to Top/QCD
- e+e- -> ff (f n.e. b) belongs to Higgs/EW but its interpretation together with BSM/NP
- Higgs -> invisible belongs to Higgs/EW, but its interpretation together with BSM/NP
- Direct production of non-SM-Higgses belongs to BSM/NP
- Exotic top decays such as t -> ch belongs to Top/QCD
The BSM/NP subgroup takes care of simulation studies for direct production of new particles. Specific BSM interpretations of analyses done in other working groups will be done in collaboration with the LCC physics working group and other theory colleagues.
Meetings and Mailing Lists
There are bi-weekly ILD Software and Analysis phone meetings ( see: http://agenda.linearcollider.org/category/131/ ) every other Wednesday.
Subscribe to the ild-detector-optimisation mailing list in order to get the invitations to these meetings.
To request a time slot for a talk in this series of meetings, send a message to the mailing list for the working group conveners: firstname.lastname@example.org
Each bi-weekly meeting has a physics focus which rotates among the three subgroups. It was decided, however, that until the current benchmark analyses are completed for the ILD Design Report (IDR) we will hold our Software and Analysis meetings weekly with no particular physics focus so as to finish up the IDR as scheduled.
The short-term schedule with physics focus is shown below
June 19: IDR benchmark analyses chaired by Daniel Jeans
June 26: IDR benchmark analyses chaired by Frank Gaede
(July 3, 4pm CEST: LCC Physics WG EPS rehearsals chaired by Gerald (2talks))
(July 5, 1 pm CEST: ILD EPS rehearsals chaired by Kiyotomo (2 talks))
(July 9, 2 pm CEST: ILD EPS rehearsals chaired by Kiyotomo (1 talk))
July 17: chaired by Keisuke Fujii
July 31: chaired by Jenny List
August 14: chaired by Frank Gaede
August 28: chaired by Daniel Jeans
for the coming ~2 months period.
There are additional subgroup mailing lists:
which are mainly for communication among active people, not so much for every interested ILD member to stay informed.
