Attended: Moskov, ... and Igor.

• During the Fall DNP-JPS Meeting, Maui, Hawaii, October 2023, we will have a joint Spectroscopy of Hyperons and Heavy Baryons at JLab and J-PARC Workshop:
• Organizers:

• DNP: Igor Strakovsky (GWU) igor@gwu.edu
• JPS: Takatsugu Ishikawa (Osaka University)

• DNP Speakers:

• Moskov Amaryan (ODU) [experiment] K-Long facility at Jefferson Lab.
• Michael Doering (GWU) [theory] Theory motivation for the K-Long experiment.
• Emilie Passemar (IU) [theory] Testing the Standard Model and looking for new physics with hyperons.

• JPS Speakers:

• Sun Young Ryu (RCNP, Osaka University) [experiment] Searching for hidden strangeness pentaquark states near phi-p threshold.
• Kotaro Shirotori (RCNP, Osaka University) [experiment] Spectroscopy of charmed baryons using hadron beam at J-PARC.
• Atsushi Hosaka (RCNP, Osaka University) [theory] Pentaquarks Pc and Pcs in a hybrid picture of hadronic molecules and five-quark states.

• During CLAS Collab meeting in Paris, Moskov spoke to Patrizia who will be ready for our ERR-I in July 2023. Let us be ready as well. Then let us think about the 7th KLF Collaboration meeting after ERR-I.

• Promotion of Hovanes Egiyan... Spokesmen of the KLF Expriment supported Eugene's proposal to appoint Hovanes as: The KLF Experiment Coordinator from Hall D . Congratulations, Hovanes

• Recent KLF talks: Mikail was invited to give a talk for MESON2023 Workshop in Krakow, Igor gave a seminar for RCNP, Osaka Univ., Moskov gave a talk for the CLAS Collaboration meeting in Paris [1].

• Our KLF Collaboration got several new mambers from Uconn, Kyoto, and Osaka Universities:

• Richard Jones, UConn;
• Toshiyuki Gogami, Kyoto University;
• Atsushi Hosaka, RCNP, Osaka University;
• Takatsugu Ishikawa, RCNP, Osaka University;
• Takashi Nakano, RCNP, Osaka University;

• On March 20th, we had a Hovanes CPS meeting discuss CPS design for Hall D and to prepare for ERR-I [2].

• Results of meeting with Fermilab group (Moskov)
• Dose Rates around Tagger Hall. SI lifetime etc. (Vitaly)
• Updates on magnet design (Tim)

• On March 13th, we had a meeting with Dave Harding and his FNAL colleagues to discuss a possibility to use FNAL EPB dipole for the CPS.

• On March 6th, we had a Hovanes CPS meeting discuss CPS design for Hall D and to prepare for ERR-I [3].

• Temperature calculations (Tim).
• Vitaly's model.
