   Opportunities for nuclear reaction studies at future facilities

   Martin Veselsky🇸🇰 · Jozef Klimo · Nikoleta Vujisicova · Georgios A. Souliotis🇬🇷

   Opportunities for investigations of nuclear reactions at the future nuclear physics facilities such as radioactive ion beam facilities and high-power laser facilities are considered. Post-accelerated radioactive ion beams offer possibilities for study of the role of isospin asymmetry in the reaction mechanisms at various beam energies. Fission barrier heights of neutron-deficient nuclei can be directly determined at low energies. Post-accelerated radioactive ion beams, specifically at the future facilities such as HIE-ISOLDE, SPIRAL-2 or RAON-RISP can be also considered as a candidate for production of very neutron-rich nuclei via mechanism of multi-nucleon transfer. High-power laser facilities such as ELI-NP offer possibilities for nuclear reaction studies with beams of unprecedented properties. Specific cases such as ternary reactions or even production of super-heavy elements are considered.

   Couplings between the $\rho$ and $D$- and $D^{\ast }$-mesons

   Bruno El-Bennich🇧🇷 · M. Ali Paracha🇵🇰 · Craig D. Roberts🇺🇸 · Eduardo Rojas🇨🇴

   We compute couplings between the $\rho$-meson and $D$- and $D^{\ast }$-mesons - $D^{(\ast )}\rho D^{(\ast )}$ - that are relevant to phenomenological meson-exchange models used to analyse nucleon-$D$-meson scattering and explore the possibility of exotic charmed nuclei. Our framework is built from elements constrained by Dyson-Schwinger equation studies in QCD, and therefore expresses a consistent, simultaneous description of light- and heavy-quarks and the states they constitute, We find that all interactions, including the three independent $D^{\ast }\rho D^{\ast }$ couplings, differ markedly amongst themselves in strength and also in range, as measured by their evolution with $\rho$-meson virtuality. As a consequence, it appears that no single coupling strength or parametrization can realistically be employed in the study of interactions between $D^{(\ast )}$-mesons and matter.

   Constraining the equation of state of nuclear matter from competition of fusion and quasi-fission in the reactions leading to production of the superheavy elements

   Martin Veselsky🇸🇰 · Jozef Klimo · Yu-Gang Ma🇨🇳 · Georgios A. Souliotis🇬🇷

   The mechanism of fusion hindrance, an effect preventing the synthesis of superheavy elements in the reactions of cold and hot fusion, is investigated using the Boltzmann-Uehling-Uhlenbeck equation, where Coulomb interaction is introduced. A strong sensitivity is observed both to the modulus of incompressibility of symmetric nuclear matter, controlling the competition of surface tension and Coulomb repulsion, and to the stiffness of the density-dependence of symmetry energy, influencing the formation of the neck prior to scission. The experimental fusion probabilities were for the first time used to derive constraints on the nuclear equation of state. A strict constraint on the modulus of incompressibility of nuclear matter $K_0=240-260$ MeV is obtained while the stiff density-dependences of the symmetry energy ($\gamma >1.$) are rejected.

   Workshop on Physics with Neutral Kaon Beam at JLab (KL2016) Mini-Proceedings

   M. Albrow · M. Amaryan · E. Chudakov · P. Degtyarenko · A. Feijoo · C. Fernandez-Ramirez · I.P. Fernando · A. Filippi · J.L. Goity · H. Haberzettl · B.C. Jackson · H. Kamano and 25 other authors

   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 excited hyperons produced by the Kaon beam on unpolarized and polarized targets with GlueX setup in Hall D. Such studies will broaden a physics program of hadron spectroscopy extending it to the strange sector. The Workshop was organized to get a feedback from the community to strengthen physics motivation of the LoI and prepare a full proposal. Further details about the Workshop can be found on the web page of the conference: http://www.jlab.org/conferences/kl2016/index.html .
