Threshold effects in P-wave bottom-strange mesons

Pablo G. Ortega, Jorge Segovia, David R. Entem +1

Using a nonrelativistic constituent quark model in which the degrees of freedom are quark-antiquark and meson-meson components, we have recently shown that the $D^{(*)} K$ thresh…

From $J / ψ$ to LHCb pentaquarks

F. Fernández, D. R. Entem, P. G. Ortega +1

The two exotic $P_{c}^{+} (4380)$ and $P_{c}^{+} (4450)$ discovered in $2015$ by the LHCb Collaboration, together with the four resonances $X (4140)$ , $X (4274)$ , $X (4500)$ and $X (4700)$ , repo…

From $J / ψ$ to LHCb pentaquark

F. Fernández, D. R. Entem, P. G. Ortega +1

The original charmonium two-body problem, like the $c c ˉ$ structure of the $J / ψ$ meson, has become more involved in the last few years with the discovery of new resonances such…

The N/D method with non-perturbative left-hand-cut discontinuity and the $^{1} S_{0}$ $N N$ partial wave

D. R. Entem, J. A. Oller

In this letter we deduce an integral equation that allows to calculate the exact left-hand-cut discontinuity for an uncoupled $S$ -wave partial-wave amplitude in potential scatterin…

Molecular components in $D_{s0}^{*} (2317)$ and $D_{s1} (2460)$ mesons

Pablo G. Ortega, Jorge Segovia, David R. Entem +1

Different experiments have confirmed that the $D_{s 0}^{*} (2317)$ and $D_{s 1} (2460)$ mesons are very narrow states located, respectively, below the $D K$ and $D^{*} K$ threshold…

Canonical description of the new LHCb resonances

Pablo G. Ortega, Jorge Segovia, David R. Entem +1

The LHCb Collaboration has recently observed four $J / ψ ϕ$ structures called $X (4140)$ , $X (4274)$ , $X (4500)$ and $X (4700)$ in the $B^{+} \to J / ψ ϕ K^{+}$ decays. We study them herein us…
