  We study the reaction cross sections ( σ _R) and root-mean-square (RMS) radii of ⁸Li and ⁸B, the halo-like nuclei, with stable target ¹²C, ²⁷Al and ⁹Be within the standard optical-limit Glauber model, using densities obtained from relativistic mean-field (RMF) formalisms and other types of distributions. It is found that the experimental σ _R can be reproduced well at high energy. The RMS radius and Δ r extracted by RMF-theory and harmonic oscillator distribution are compared. We find that the RMS radius and Δ r of ⁸B are larger than those of ⁸Li. In addition, we analyze in detail the relationship between σ _R and density distribution.

  We present an explicit connection between the symmetries in a Very Special Relativity (VSR) and isometric group of a specific Finsler space. It is shown that the line element that is invariant under the VSR symmetric group is a Finslerian one. The Killing vectors in Finsler space are constructed in a systematic way. The Lie algebras corresponding to the symmetries of VSR are obtained from a geometric famework. The dispersion relation and the Lorentz invariance violation effect in the VSR are discussed.

  We calculate the D → η transition form factor in light-cone sum rules by taking improved current correlators to avoid the pollution from the twist-3 wave function. We get consistent results of the D ⁺ → η ^(')1 ⁺ν ₁ decays with the experimental data. By comparing the difference between the results of the branching ratios of D ⁺ → η ^(')1 ⁺ν ₁ from a two-pole parameterization model and from a BZ parameterization model, we find that the two-pole model and the BZ model are comparably believable. One way is supposed for the determination of the η-η' mixing angle from the dependence of the branching ratios of D ⁺ → η ^(')1 ⁺ν ₁ decays on the η-η' mixing angle.
