Agenda [attended: Moskov, Nick, Michail, Justin, Chan, and Igor]

1) Promising for the coming proposal (for both LH2 and LD2 targets):

• Mikhail will consider K_Lp-->K⁺n process to show a full MC, estimation of possible statistics and expected uncertainties for angular distributions. Then he plan to evaluate background from np->nK⁺Λ and np->π⁺nn (with pion miss-identification as Kaon).

• Nick is providing the studies for the Cascade. K_Lp-->K⁺Ξ⁰. He has already constructed the generator that Mikhail and he are using for our studies and he is finishing up reconstruction studies for the cascade. He plans to provide studies of cascade polarization. He can also generate some excited cascades and study resolutions and backgrounds. Then he is flexible in helping where there is more need. It was a very hectic beginning of the year, and didn't have any time to put in to detailed studies, but he now has a bit more time that he can spend on this project.

Then, Nick can easily do the K_Lp-->π⁺Λ and introducing a neutron target in his generator with a Fermi momentum. He needs to include the polarization in the generator and then do more detailed studies.

Nick's slides [1].

• Lei thinks that he could pitch in for the strange mesons physics case (and simulation). He can also help the overall case for cascade and excited hyperons

• Pavel will consider a conceptual design for the compact photon source (CPS).

• Igor will present neutron background MC results using the MCNP6 transport code. It has to satisfy RadCon.

• Justin will consider the possibility to improve the time resolution of the start counter.

• Kijun:

• Moskov spoke about possibility to do K-pi study [2]

Theoretical details are at Emilie Passemar's slides on the KL2016 [3]. The bottom line is that we will have a unique opportunity to get info about κ-meson.
