Abstract: The current paper presents a determination of $K^0_S$ and $\Lambda/\bar{\Lambda}$ fragmentation functions (FFs) from QCD analysis of single-inclusive electron-positron annihilation process (SIA). Our FFs determinations are performed at next-to-leading order (NLO), and for the first… read more here.

Abstract: We present the calculations of isospin splitting mass of pions and nucleons in the Sakai–Sugimoto model of holographic QCD. We find that mπ±− mπ0 ≃ 1.8MeV and the electromagnetic mass difference of nucleons, (Mp −… read more here.
