Attended: Sean, Eugene, Vitaly, Hovanes, Sashi, Richard, Keigo, Mikhail, Alex, Stuart, Moskov, and Igor.
- Announcements
- Igor reported that the PWA groups BnGa (Andrey) is waiting for our contribution for Xi study (Stuart) and JuBoWa (Deborah) for for our contribution for Lambda study (Marshall).
- Mikhail reported about new activity with REKEN (Kenta Itahashi) group to sudy Lamba p --> Lambda p.
-- Simulation of KL flux using PYTHIA by Eugene. Eugene updated the slides: -- the W/Cu ratio in the plug was changed to 90/10. With that, about 5% of the plug volume appears to be empty. It would effectively increase the absorption length of the plug material by ~3%. Eugene noticed that the absorption length in pure W is rather 6.8 cm than 7.0 cm I used before. This would decrease the absorption length of the plug. This resulted in no significant change in the absorption length of the plug. It is still 7.8 cm (using the same method). An additional 5cm plug would kill about 50% of KLs. At this time I am not sure what the uncertainty of the evaluated absorption length is. It needs further studies.
-- Vitaly's slides for KL + p --> KL + p reconstruction.
