Predictions for the ${\Lambda }_b\to J/\psi \Lambda (1405)$ decay

Luis Roca, Maxim Mai, Eulogio Oset +1

We calculate the shape of the $\pi \Sigma$ and $\bar{K}N$ invariant mass distributions in the ${\Lambda }_b\to J/\psi \pi \Sigma$ and ${\Lambda }_b\to J/\psi \bar{K}N$ decays that are dominated by the $\Lambda (1405)$ reso…
