Amplitude analysis and the nature of the Zc(3900)
JPAC Collaboration, A. Pilloni, C. Fernandez-Ramirez +5
The microscopic nature of the XYZ states remains an unsettled topic. We show how a thorough amplitude analysis of the data can help constraining models of these states. Specificall…
The Joint Physics Analysis Center: Recent results
Cesar Fernandez-Ramirez
We review some of the recent achievements of the Joint Physics Analysis Center, a theoretical collaboration with ties to experimental collaborations, that aims to provide amplitude…
Three-body final state interaction in updated
P. Guo, I. V. Danilkin, C. Fernández-Ramírez +2
In view of the recent high-statistic KLOE data for the decay, a new determination of the quark mass double ratio has been done. Our approach relies on a dispersi…
Studying the P_c(4450) resonance in J/psi photoproduction off protons
A. N. Hiller Blin, C. Fernández-Ramírez, A. Jackura +4
A resonance-like structure, the P_c(4450), has recently been observed in the J/psi p spectrum by the LHCb collaboration. We discuss the feasibility of detecting this structure in J…
Workshop on Physics with Neutral Kaon Beam at JLab (KL2016) Mini-Proceedings
M. Albrow, M. Amaryan, E. Chudakov +34
The KL2016 Workshop is following the Letter of Intent LoI12-15-001 "Physics Opportunities with Secondary KL beam at JLab" submitted to PAC43 with the main focus on the physics of e…
Amplitude analysis of scattering
Cesar Fernandez-Ramirez
We present the results of a coupled-channel model for scattering in the resonance region. The model fulfills unitarity, has the correct analytical properties for the amp…
