  New LHCb Collaboration results on pentaquarks with hidden charm [1] are
discussed. These results fit nicely in the hadrocharmonium pentaquark scenario
[2,3]. In the new data the old LHCb pentaquark $P_c(4450)$ splits into two
states $P_c(4440)$ and $P_c(4457)$. We interpret these two almost degenerate
hadrocharmonium states with $J^P=1/2^-$ and $J^P=3/2^-$ as a result of
hyperfine splitting between hadrocharmonium states predicted in [2]. It arises
due to QCD multipole interaction between color-singlet hadrocharmonium
constituents. We improve the theoretical estimate of hyperfine splitting [2,3]
that is compatible with the experimental data. The new $P_c(4312)$ state finds
a natural explanation as a bound state of $\chi_{c0}$ and a nucleon, with
$I=1/2$, $J^P=1/2^+$ and binding energy 42 MeV. As a bound state of a spin-zero
meson and a nucleon, hadrocharmonium pentaquark $P_c(4312)$ does not experience
hyperfine splitting. We find a series of hadrocharmonium states in the vicinity
of the wide $P_c(4380)$ pentaquark that can explain its apparently large decay
width. We compare the hadrocharmonium and molecular pentaquark scenarios and
discuss their relative advantages and drawbacks.
