Study of possible $D N D^{*}$ bound states

Victor Montesinos, Jing Song, Wei-Hong Liang +3

We start from a recently favored picture in which the $Λ_{c} (2940)$ and $Λ_{c} (2910)$ correspond mostly to $N D^{*}$ bound states with $J^{P} = 1/ 2^{-}, 3/ 2^{-}$ and then add a $D$ as a third…

Calculation of the ratios and absolute rates of the $Ξ_{b}^{-} \to π^{-} (D_{s}^{-}) Ξ_{c}^{0} (2790) (Ξ_{c}^{0} (2815))$ and $Ξ_{b}^{-} \to ν ˉ_{l} l Ξ_{c}^{0} (2790) (Ξ_{c}^{0} (2815))$ decays

R. Pavao, W-H Liang, J. Nieves +1

In this work we calculate the ratios of rates of the $Ξ_{b}$ nonleptonic and semileptonic decays into the $Ξ_{c}$ (2790) and $Ξ_{c}$ (2815) ( $Ξ_{c}^{*}$ ) resonances. These resonances are dynam…

Predictions for $Ξ_{b}^{-} \to π^{-} (D_{s}^{-}) Ξ_{c}^{0} (2790) (Ξ_{c}^{0} (2815))$ and $Ξ_{b}^{-} \to ν ˉ_{l} l Ξ_{c}^{0} (2790) (Ξ_{c}^{0} (2815))$

R. P. Pavao, W. H. Liang, J. Nieves +1

We have performed the calculations for the nonleptonic $Ξ_{b}^{-} \to π^{-} Ξ_{c}^{0} (2790) (J = \frac{1}{2})$ and $Ξ_b^- \rightarrow π^- \ Ξ_c^0 (2815) \left(J=\frac{3}{…

The LHCb pentaquark as a $D ˉ^{} Σ_{c} - D ˉ^{} Σ_{c}^{*}$ molecular state

L. Roca, J. Nieves, E. Oset

We perform a theoretical analysis of the $Λ_{b} \to J / ψ K^{-} p$ reaction from where a recent LHCb experiment extracts a $Λ (1405)$ contribution in the $K^{-} p$ spectrum close to threshol…

Combining heavy quark spin and local hidden gauge symmetries in the dynamical generation of hidden charm baryons

C. W. Xiao, J. Nieves, E. Oset

We present a coupled channel unitary approach to obtain states dynamically generated from the meson baryon interaction with hidden charm, using constraints of heavy quark spin symm…

N_c and m_pi dependence of rho and sigma mesons from unitarized Chiral Perturbation Theory

G. Rios, C. Hanhart, J. R. Pelaez

We review our work on the rho and sigma resonances derived from the Inverse Amplitude Method. In particular, we study the leading 1/N_c behavior of the resonances masses and widths…
