The first full amplitude analysis of $B^+ \to J/\psi\phi K^+$ with $J/\psi \to \mu^+\mu^−, \phi \to K^+ K^−$ decays is performed with a data sample of 3  $fb^{−1}$ of $pp$ collision data collected at $\sqrt{s}=7$ and 8 TeV with the LHCb detector. The data cannot be described by a model that contains only excited kaon states decaying into $\phi K^+$, and four $J/\psi\phi$ structures are observed, each with significance over 5 standard deviations. The quantum numbers of these structures are…

Quark Structure of the X (4500), X (4700) and χ c (4P,5P) States

Observation of a New Excited D_{s}^{+} Meson in B^{0}→D^{-}D^{+}K^{+}π^{-} Decays.

The new resonance, denoted as D_s0(2590)^{+), is a strong candidate to be the D_{s}(2^{1}S_{0})^{+} state, the radial excitation of the pseudoscalar ground-state D- meson.

The resonances $X(4140)$, $X(4160)$, and $P_{cs}(4459)$ in the decay of $\Lambda_b\to J/\psi\Lambda\phi$

We study the decay of $\Lambda_b\to J/\psi\Lambda\phi$ by taking into account the intermediate resonances $X(4140)$, $X(4160)$, and $P_{cs}(4459)$. In addition to the peak of the $X(4140)$, we also

Amplitude analysis of the B+→D+D−K+ decay

The three quark system is studied in a relativized version of the quark potential model with chromodynamics and the spectrum of baryons is described with parameters consistent with those of an analogous study of meson spectroscopy.

Cusps and Exotic Charmonia

A simple, causal and analytic model of final state rescattering is used to describe all available data on the exotic resonances Zc(3900) and Zc(4025). The model provides a compelling and accurate

Search for the X(4140) state in B +→J/ψφK + decays

A search for the X(4140) state in B +→J/ψφK + decays is performed with 0.37fb -1 of pp collisions at √s=7TeV collected by the LHCb experiment. No evidence for this state is found, in 2.4σ

Evidence for a new resonance and search for the Y(4140) in the gammagamma-->phiJ/psi process.

The process gammagamma-->phiJ/psi is measured using a data sample of 825 fb{-1} collected with the Belle detector, and no signal for the Y(4140)-->phiJ /psi structure reported by the CDF Collaboration in B-->K{+}phiJ./psi decays is observed.

Z b and Z c exotic states as coupled channel cusps

It is demonstrated that the candidate tetraquark states $Z_b(10610)$, $Z_b(10650)$, $Z_c(3900)$, and $Z_c(4025)$ are coupled channel cusp effects. The model explains in a natural way the masses and
