We calculate the masses of χc(3P) states with threshold corrections in a coupled-channel model. The model was recently applied to the description of the properties of χc(2P) and χb(3P) multiplets (Ferretti and Santopinto in Phys Lett B 789:550, 2019]. We also compute the open-charm strong decay widths of the χc(3P) states and their radiative transitions. According to our predictions, the χc(3P) states should be dominated by the charmonium core, but they may also show small meson-meson components. The X(4274) is interpreted as a cc¯ χc1(3P) state. More information on the other members of the χc(3P) multiplet, as well as a more rigorous analysis of the X(4274)’s decay modes, are needed to provide further indications on the quark structure of the previous resonance.

Nuclear structure solving problems of fundamental physics
Suhonen, Jouni (Società Italiana di Fisica, 2019)Nuclear-structure calculations are important inputs for solving problems of fundamental physics. Such problems are related with, e.g., neutrinos and dark-matter particles and their interactions with atomic nuclei. In this ... -
ϕ meson production in p+Al, p+Au, d+Au, and 3He+Au collisions at √sNN = 200 GeV
PHENIX Collaboration (American Physical Society (APS), 2022)Small nuclear collisions are mainly sensitive to cold-nuclear-matter effects; however, the collective behavior observed in these collisions shows a hint of hot-nuclear-matter effects. The identified-particle spectra, ... -
Clusterization and Strong Coulpled-Channels Effects in Deuteron Interaction with 9Be Nuclei
Urazbekov, Bakytzhan; Denikin, A. S.; Lukyanov, Sergei; Itaco, N.; Janseitov, D.; Mendibayev, K.; Burjan, Vaclav; Kroha, Vaclav; Mrazek, J.; Trzaska, Wlasyslaw; Harakeh, M. N.; Etasse, D.; Stefan, I.; Verney, David; Issatayev, T.; Penionzhkevich, YU; Kuterbekov, Kairat; Zholdybayev, T. (Institute of Physics Publishing Ltd., 2019)Angular distributions of protons, deuterons, tritons and alphaparticles emitted in the d + 9Be reaction at Elab=19.5 and 35.0 MeV have been measured. The elastic scattering channel is analysed in the framework of both the ... -
