In this talk, I will provide distinguishable consequences of the $Z_{cs}(3985)$ and $Z_{cs}(4000)$ as two or one state. In the one-state scheme, $Z_{cs}(3985/4000)^−$ state is the U-spin partner of $Z_c(3900)^−$. Otherwise, the SU(3) flavor partner of $Z_{c}(3900)$ is $Z_{cs}(4000)$ rather than the $Z_{cs}(3985)$. Another two important predictions in the two-state scheme are the existence of a ... More

We have recently studied the interactions of $D-\bar D + c.c$ with a nucleon, with the motivation to find formation of $P_c$ like states. We consider all interactions in s-wave and solve scattering equations. We find formation of nucleons with hidden charm, spin 1/2, 3/2 and positive parity. We earlier studied the interaction of $D-\bar D$ with a kaon, where a $K^*$-meson is found to arise. In th ... More

We present a recent investigation on the production of $P_{cs}(4459)$ in the exclusive $K^-p\to J/\psi\Lambda$ reaction using both the effective Lagrangian and Regge approaches. We assume six different spin and parity assignments, i.e., $1/2^\pm$, $3/2^\pm$ and $5/2^\pm$ to the newly found $P_{cs}$. The total and differential cross sections for the $K^-p\to J/\psi\Lambda$ reaction are calculated. ... More

We have studied the $e^+ e^- \to K^+ ( D_s^{*-} D^0 + D_s^- D^{*0})$ reaction[1] recently measured at BESIII, from where a new exotic $Z_{cs}$ state has been reported. We study the interaction of $\bar D_s D^*$ with the coupled channels. Although our picture does not produce a bound state nor resonance, the interaction of the coupled channels has sufficient strength to produce the enhancement clo ... More
