Analysis of the $B^{+} \to J / ψ ϕ K^{+}$ data at low $J / ψ ϕ$ invariant masses and the $X (4140)$ and $X (4160)$ resonances

En Wang, Ju-Jun Xie, Li-Sheng Geng +1

We have studied the $J / ψ ϕ$ mass distribution of the $B^{+} \to J / ψ ϕ K^{+}$ reaction from threshold to about 4250 MeV, and find that one needs the contribution of the $X (4140)$ with a nar…

Relativistic baryon-baryon interactions in chiral perturbation theory

Xiu-Lei Ren, Kai-Wen Li, Li-Sheng Geng

We report on the recent studies of leading order baryon-baryon interactions in covariant baryon chiral perturbation theory. In the strangeness $S = 0$ sector, one can achieve a rathe…
