Attended: Moskov, Vitaly, Keogo, Mikhail, Alex, Marchall, Sean, Richard, and Igor.

• Mikhail has skripts of several reactions which we used for the proposal. He sent zip file to everybody.

Kego, please, implement tham.

• From Mikhail- What I have and what we did:

-- 1) We have a KLF generator which can generate majority of 2 body reactions (written by Nick and accessible and github).

-- 2) I have scripts from Ilya which can reconstruct Lambda pi+ and p K_s reactions.

-- 3) This script was modified by me to reconstruct K+n reaction and by Nick' to fully reconstruct K_Ln-> K+Xi^-(Xi^- -> Lambda pi...) reaction. [generation->geant->reconstruction].

-- 4) Based on Nick's results we have prepared a mock data for the K_L p-> K+ Xi0 and made a full PWA with BnGa by Andrey.

-- 5) There are some reconstruction scripts from Nick. The archive also include reconstruction scripts from Simon.

• Proposal is saying that we have to have a 64 ns bunch spacing but acclerator folks (Geoff) using new injector are working to allow 128 ns. That allows to access to P_KL ~ 200 MeV/c.

• There is not pentaquark search in the proposal, just there is a item for a single particle detection. For that purposes, we will use input from Jido of Tokyo Tech for both KL p --> K+ n and KL p --> KS p. Vitaly will do that.

• Mikhail promised to evaluate rate and volume of data for several reactions.

• Alex promised to consider a repository space for the KLF data.

• On the reconstruction soft development, a new GW postdoc, Marshall',' will focus and Sean will help him.
