April 4th, 2023

Attended: Moskov, Jim, Justin, Sean, Eugene, Hovanes, and Igor. Mikhail is in charge of the Durham conference and he cannot attend our meeting today. Jim left us at 8:25 am.

• Eugene informed us that Patrizia' is scheduled the time for the ERR-I as the 1st week of August, starting Monday, July 31st. Patrizia' promised to asign members of the committee for ERR-I.

• During the 6th Joint Meeting of the APS Division of Nuclear Physics and the Physical Society of Japan (HAW22), Hyatt Regency Maui, Lahaina (Maui), Hawaii, October 7-12, 2023, we will have a joint Spectroscopy of Hyperons and Heavy Baryons at JLab and J-PARC Workshop:
• Organizers:

• DNP: Igor Strakovsky (GWU)
• 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:

• Atsushi Hosaka (RCNP, Osaka University) [theory] Pentaquarks Pc and Pcs in a hybrid picture of hadronic molecules and five-quark states.
• 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.

• During CLAS Collab meeting in Paris, Moskov spoke to Patrizia who will be ready for the KLF 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

• Spokespersons of KLF project and Hall D leader, Eugene Chudakov agreed that Hovanes Egiyan will act as Hall D coordinator or the beamline design and installations of hardware components up to KPT (Beryllium Target). All decisions about the choice of CPT must be agreed and approved by Hall D coordinator before it goes to realization. This was accepted by Hovanes Egiyan during KLF spokespersons meeting on April 4th 2023.

• Recent KLF talks: Mikail was invited to give a talk for MESON2023 Workshop in Krakow, Igor gave a Seminar for RCNP, Osaka Univ., and Moskov gave two talks for the CLAS Collaboration meeting in Paris and for the Intersection of Nuclear Structure and High-Energy Nuclear Collisions workshop, INT in Seattle, [1].

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

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

The full list of members of the KLF Collaboration is on Wiki.

• 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 [4].

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