$$P_{cc}^N$$ P cc N states in a unitarized coupled-channel approach
European Physical Journal C: Particles and Fields, 2023 Starting from an effective Lagrangian with heavy quark spin symmetry embedded, the coupled-channel dynamics of the doubly charmed systems $$D^{(*)} \Sigma _c^{(*)}$$ D ( ∗ ) Σ c ( ∗ ) is investigated. The potential underlying our investigation includes t-

Implications of an increased Λ-separation energy of the hypertriton
Physics Letters B, 2020 Stimulated by recent indications that the binding energy of the hypertriton could be significantly larger than so far assumed, requirements of a more strongly bound HΛ3 state for the hyperon-nucleon interaction and consequences for the binding energies ...

The width of the Roper resonance in baryon chiral perturbation theory
Physics Letters B, 2016 We calculate the width of the Roper resonance at next-to-leading order in a systematic expansion of baryon chiral perturbation theory with pions, nucleons, and the delta and Roper resonances as dynamical degrees of freedom.

The Y(4230) as a D1D molecule [PDF]
EPJ Web of Conferences. We show that the currently available data are consistent with Y(4230) being a D1D¯ hadronic molecule. By a simultaneous fit to data from e+e− → D0D*−π+, J/ψπ+π−, J/ψK+ K−, hcπ+π−, J/ψη, χc0ω, χc1(3872)γ and µ+µ−, we demonstrate that this single state ...

Phenomenology of near-threshold states: a practical parametrisation for the line shapes
EPJ Web of Conferences, 2017 In the last decade many states in the spectrum of charmonium and bottomonium have been observed experimentally above the lowest open-flavour threshold.

Generating a resonance-like structure in the reaction $$B_c\rightarrow B_s \pi \pi $$ B c → B s π π
European Physical Journal C: Particles and Fields, 2017 We investigate the process $$B_c^+\rightarrow B_s^0\pi ^+\pi ^0$$ B c + → B s 0 π + π 0 via $$B\bar{K}^*$$ B K ¯ ∗ rescattering. The kinematic conditions for triangle singularities are perfectly satisfied in the rescattering diagrams.

Lattice QCD and Baryon-Baryon Interactions: HAL QCD Method
Frontiers in Physics, 2020 In this article, we review the HAL QCD method to investigate baryon-baryon interactions, such as nuclear forces in lattice QCD. We first explain our strategy in detail to investigate baryon-baryon interactions by defining potentials in field theories ...

Hadronic and Hadron-Like Physics of Dark Matter [PDF]
Symmetry, 2019 The problems of simple elementary weakly interacting massive particles (WIMPs) appeal to extend the physical basis for nonbaryonic dark matter. Such extension involves more sophisticated dark matter candidates from physics beyond the Standard Model (BSM) of elementary particles.
