Using 980 ${rm fb}^{-1}$ of data {collected} with the Belle detector operating at the KEKB asymmetric-energy $e^+e^-$ collider, we report the measurements of the masses, and the first measurements of the instrinsic widths, of the $Sigma_c(2455)^+$ and $Sigma_c(2520)^+$ charmed baryons. We find $M(Sigma_c(2455)^+)-M(Lambda_c^+) = 166.17pm 0.05^{+0.16}_{-0.07} {rm MeV}/c^2$, $Gamma(Sigma_c(2455)^+) = 2.3 pm 0.3 pm 0.3 {rm MeV/c^2}$, $M(Sigma_c(2520)^+)-M(Lambda_c^+) = 230.9 pm 0.5 ^{+0.5}_{-0.1} {rm MeV}/c^2$, and $Gamma(Sigma_c(2520)^+) = 17.2^{+2.3 +3.1}_{-2.1 -0.7} {rm MeV}/c^2$, where the uncertainties are statistical and systematic, respectively. These measurements can be used to test models of the underlying quark structure of the $Sigma_c$ states.
We present measurements of the masses and decay widths of the baryonic states $Sigma_{c}(2455)^{0/++}$ and $Sigma_{c}(2520)^{0/++}$ using a data sample corresponding to an integrated luminosity of 711 fb$^{-1}$ collected with the Belle detector at th
We report an experimental determination of the isospin of $Lambda_c(2765)^+/Sigma_c(2765)^+$ using 980 fb$^{-1}$ data in the $e^+e^-$ annihilation around $sqrt{s} = 10.6$ GeV collected by the Belle detector located at the KEKB collider. The isospin p
We investigate the strong force fields and stabilities of the nucleon and the singly heavy baryon $Sigma_c$ within the framework of the chiral quark-soliton model. Having constructed the pion mean fields in the presence of the $N_c-1$ level quarks se
We evaluate the $Lambda_cSigma_cpi$ coupling constant ($G_{Lambda_c Sigma_c pi}$) and the width of the strong decay $Sigma_c rightarrowLambda_c pi$ in 2+1 flavor lattice QCD on four different ensembles with pion masses ranging from 700 MeV to 300 MeV
In this article, we analyze the strong vertexes $Sigma_{c}^{*}ND$ and $Sigma_{b}^{*}NB$ using the three-point QCD sum rules under the Dirac structure of $q!!!/p!!!/gamma_{mu}$. We perform our analysis by considering the contributions of the perturbat
