Summary: In this study, lattice QCD data in the open-charm sector is analyzed based on the chiral SU(3) Lagrangian. The low-energy constants are adjusted to reproduce the open-charm meson masses on lattice QCD ensembles. The effect of lefthand cuts is considered for the first time, and coupled-channel interaction terms are used. The elastic and inelastic scattering phase shifts are faithfully reproduced on ensembles with different pion masses.

Summary: In this study, the electroproduction data of pion and eta particles are jointly analyzed for the first time up to a center-of-mass energy of 1.6 GeV. The results provide insights into the determination of resonance amplitudes in the near-threshold region. It is found that some amplitudes can be well determined while others require data over a wider energy range.

Summary: A refined investigation on light flavor meson-baryon scatterings was conducted using a dynamical coupled-channel approach. The study extended the channel space and extracted the spectra of N* and Delta resonances, as well as questioning the existence of bound states of the omega meson in nuclear matter through the extraction of a negative value of the omega N elastic spin-averaged scattering length.

Summary: A novel framework is proposed to extract near-threshold resonant states from lattice QCD energy levels and is applied to study the structures of positive parity D-s mesons. The quark model, quark-pair-creation mechanism, and D-(*K-) interaction are incorporated into the effective field theory to analyze the composition of the D-s mesons. The results show that the physical D-s0* (2317) and D-s1* (2460) are mixtures of bare c (s) over bar core and D-(*K-) component, while the D-s1* (2536) and D-s2* (2573) are dominated by the bare CS%.

Summary: Using dispersion theory, the Sigma-to-Lambda transition form factors in electromagnetic interactions are calculated considering the pion electromagnetic form factor, SU(3) chiral perturbation theory, the baryon decuplet, and the pi pi- K coupled-channel effect. The electric form factor is significantly affected by the inclusion of the K channel, while the magnetic form factor is minimally affected. The uncertainties in the three-flavor chiral perturbation theory are estimated using a bootstrap sampling method.

Summary: Heavy hadron spectroscopy was well understood in the naive quark model until the discovery of X(3872) in 2003, which revealed the limitations of the simple model and the need to consider coupling to two-meson states for a better understanding of excited states of heavy mesons.

Summary: Complete calculations of the electromagnetic form factors of the Omega(-) have been presented in both spacelike and timelike regions. The analyses are conducted within the covariant spectator quark model, and the results are compared with lattice QCD data and experimental data from CLEO. The impact of large-Q(2) correlations and possible solutions are also examined.

Summary: In this study, a comprehensive analysis of the deuteron charge and quadrupole form factors based on the latest two-nucleon potentials and charge-density operators derived in chiral effective field theory was presented. By adjusting short-range terms in the two-nucleon charge-density operator, the values of the deuteron structure radius and quadrupole moment were predicted. The study also analyzed various sources of uncertainty in the predictions and updated the determination of the neutron charge radius.

Summary: This paper investigates the synchronization behaviors of symmetrical neuronal networks constructed by fractional-order Hindmarsh-Rose models under electromagnetic radiation. The synchronization degree is found to be influenced by the fractional-order q and feedback gain parameter k(1), leading to various synchronization transitions. Changes in memory-conductance parameter beta, k(1) and q affect the synchronization behaviors in a symmetrical ring neuronal network.

Summary: Building on the CT18 global fit, this study presents a new calculation of the photon content of the proton using the LUX formalism. Two variations of the LUX ansatz are explored, showing general agreement but with moderate discrepancies at high or low x-values. The study also investigates the effects of variations in the LUX inputs on the photon PDF.
