We show recent results on excited hadrons at Belle (II) experiment. First, we discuss an observation of excited $S=-3$ hyperon ${\mathrm {\Omega } (2012) }^{-}$ and properties of $\Lambda(1670)$ and $\Sigma(1385)^+$ hyperons. In the analysis procedure, the importance of interplay between experiment and theory will be demonstrated. In addition, recent results on excited charmed baryons are...
Medium modifications on the distribution functions of the spin-1 vector meson as well as its medium properties are investigated in the quark-level chiral effective theory of QCD. Nuclear medium effects are also obtained from the same chiral effective model. Remarkable results on the distribution functions and properties of vector meson in the nuclear medium will be presented and discussed.
We perform a sensitivity study of an unbinned angular analysis of the $B\to D^*(D\pi)\ell\nu$ decay, including the contributions from the right-handed (R.H.) vector current. We show that the Wilson coefficient of the R.H. vector current can be strongly constrained by measuring the normalized angular observables $\langle g_i \rangle$ (i=1,2,...,11) without the intervention of the $V_{cb}$ puzzle.
We investigate the masses and radii of neutron stars within the framework of the in-medium modified chiral soliton model, considering the effects of surrounding baryonic environment on the properties of in-medium baryons. The equation of state describing an infinite and asymmetric nuclear matter are obtained by introducing the density-dependent functions. To extrapolate the high density and...
We investigate meson resonances with quantum numbers $J^P=1^+$ and $S=0$ from the interaction of the pseudoscalar meson with the vector meson using the coupled-channel approach. Having included all possible one-meson exchange diagrams without an axial-vector meson one, we reproduce the experimental data on charge exchange reaction in $a_1$, $h_1$ and $b_1$ channels. This result exhibits the...
We investigate the transverse single-spin asymmetry (TSSA) for the very forward neutral pion production by employing the triple-Regge exchanges. The TSSA is ratio of spin-dependent and spin-averaged differential cross section. In the RHICf energy($\sqrt{s}=510\,\mathrm{GeV}$), the inclusive $p+p^\uparrow\to\pi^0+X$ process will be diffractive, so that $d\sigma$ can be expressed in terms of the...
We investigate the mass spectrum and electromagnetic transitions of charmonia, emphasizing the instanton effects on them. The heavy-quark potential consists of the Coulomb-like potential from one-gluon exchange and the linear confining potential. We introduce the nonperturbative heavy-quark potential derived from the instanton vacuum. We also consider the screened confining potential, which...
We investigate the gravitational form factors of the baryon octet within the framework of the chiral quark-soliton model, also known as the pion mean-field approach, emphasizing the effects of flavor SU(3) symmetry breaking on the form factors. The $D$-term form factors provide information on the stability conditions of the baryon octet in terms of the pressures and shear forces inside them....
In the present talk, we present the axial-vector transition form factors of the lowest-lying heavy baryons within the framework of the chiral quark-soliton model. In the infinitely heavy quark mass limit, a heavy quark can be considered as a color static source. We consider the linear rotational $1/N_{c}$ and strange current quark mass corrections. The results of axial-vector transition form...
Recently, the 3D EMT form factors and their distributions for a spin-1 particle have been studied in various papers. However, to have true probabilistic distributions, one has to go to the infinite momentum frame instead of the 3D Breit frame. A price to pay is that the EMT distributions should be defined in the 2D space. In this talk, we first provide the model-independent formalism for the...
