Belle II @ Wayne State University

US Belle II Science Readiness Briefing Jan 9-10 2019

• Wayne State University group members have experience on BaBar, CLEO, and Belle.

• Our physics interests include measuring P and CP violation in B meson and bottomonium decays, and rare charm decays.

• We have been heavily involved with the commissioning detector (BEAST II) during Phases I and II; this will continue into Phase III.

• Our particular involvement has been with the PIN diodes and Large Angle Beamstrahlung Monitor (LABM).

• In addition to DOE funding we have funding from US-Japan funds and from Wayne State University.

Faculty Summary


Matthew Barrett, 100% Belle II. Research Assistant Professor 100% Belle II: Work on PIN diodes in Phases II and III. Analysis of charmless three body B meson decays for Belle and Belle II. Belle II diversity officer. Number of postdocs: 0. Number of students: 0 (assists with supervision of professor Cinabro's student(s)).

• Postdoc 1 Minakshi Nayak: 100% on Belle II– Worked on Belle II at WSU until May 2018, based at KEK.– Now at Tel Aviv University.– Worked on PIN diodes for BEAST II Phase I.– Search for D-mixing in CP-odd mode: D→K

sω, ω → π+π-π0.

– Worked on Ks identification and data processing/charm skim

for Belle II.

• Future Postdoc: 100% on Belle II– To start working on Belle II in 2019.– Will be based mainly at KEK.

Postdoc Summary


• Student 1 (Janaka) Kospalage Kumara: 100% on Belle II– Started on Belle II in 2016.– Working on analysis and starting computing/software work.– Will be based at KEK later in 2019.– Thesis topic: Analysis of BK

S0 with Belle II data.

– Projected graduation in 2020.

• Student 2 Samuel Doeg Isaguirre: 100% on Belle II– Started on Belle II in 2016.– Working on LABM for Phases II and III.– Has made trips to KEK to work on LABM installation and– operation.– Thesis topic: Large Angle Beamstrahlung Monitor for Belle II.– Projected graduation in 2020.

Graduate Student Summary


• 1-2 Undergraduate students per year (from REU (Research Experiences for Undergraduates) Program): 2018 – 2 students, total 400 hours/student/year. – 2018 students worked on a search for Petrovian Glueballs,

and analysis prospects for B0K+0.– Belle II REU students write up projects as Belle II notes.

• Engineer: Alfredo Gutierrez– Support for PIN diodes and LABM construction and

Maintenance.– Will work on the FELIX DAQ upgrade.– Maintains Wayne State local Belle II computing server.– 25% of time on Belle II.– Funded from DOE grant.

Other People


• BEAST II LABM and PIN diodes.– LABM used to directly monitor beam parameters and

determine position of interaction point. – Deployed in Phases I and II; will be deployed during Phase

III with new (upgraded) mirrors. Paper on Phase I results submitted to NIM.

– PIN diodes used to monitor the ionising radiation dose around the beampipe and near the TPCs (Phase I), and around the QCSS final focus magnets (Phases II-III).

– Phase I results published in Beast II Phase I paper (See Sven Vahsen's talk). Diodes redesigned for Phase II. Following Phase II, will be used for QCSS warning system for Phase III.

– As commissioning era of Phase III draws to a close, we plan to transition to computing activities, or FELIX DAQ upgrade or similar activities depending on future postdoc hire.

Belle II Activities


• Physics activities– M. Nayak working with D. Cinabro to finish analysis of

D→Ksω, ω→π+π-π0 for Belle.

– Work on Dalitz plot analysis of B+KS0 and B0K+0

with analysis code being developed for Belle II also used on Belle data.

– Search of P and CP violation in Bottomonium decays – Belle analyses being migrated to Belle II.

Group members have contributed code to the BEAST II and analysis packages of basf2.
