Some insights into the newly observed $Z_c(4100)$ in $B^0\to \eta_c K^+ \pi^-$ by LHCb

The newly reported exotic signal $Z_c(4100)$ by the LHCb Collaboration in the invariant mass spectrum of $\eta_c\pi^-$ in $B^0\to \eta_c K^+ \pi^-$ has been a new experimental evidence for an exotic meson containing four constituent quarks. Although the present experimental information is very limit...
