After discussing the various possible interpretations of the Y(4143) signal observed by the CDF collaboration in the J/{psi}{phi} mode, we tend to conclude that Y(4143) is probably a D{sub s}*D{sub s}{sup *} molecular state with J{sup PC}=0{sup ++} or 2{sup ++} while Y(3930) is its D*D* molecular partner as predicted in our previous work [X. Liu, Z. G. Luo, Y. R. Liu, and Shi-Lin Zhu, Eur. Phys. J. C 61, 411 (2009)]. Both the hidden-charm and open-charm two-body decays occur through the…

Are the X(4160) and X(3915) charmonium states

Inspired by the newly observed states X(4160) and X(3915), we analyze the mass spectra of these states in different quark models and calculate their strong decay widths by the {sup 3}P{sub 0} model.

Exploring the molecular scenario of X(4160)

In this work, we investigate the decays of meson X (4160) which is considered as a hadronic molecule states of I G J PC = 0 + 2 ++ . By using the effective lagrangian approach, we calculate the widths

Understanding the internal structures of X(4140), X(4274), X(4500) and X(4700)

We investigate the newly observed X(4500) and X(4700) based on the diquark–antidiquark configuration within the framework of QCD sum rules. Both of them may be interpreted as the D-wave

The open-charm radiative and pionic decays of molecular charmonium Y(4274)

In this work, we investigate the decay widths and the line shapes of the open-charm radiative and pionic decays of Y(4274) with the $D_{s}\bar{D}_{s0}(2317)$ molecular charmonium assignment. Our

Tetraquark state candidates: $Y(4140)$, $Y(4274)$ and $X(4350)$

In this article, we tentatively assign the $Y(4140)$, $Y(4274)$ and $X(4350)$ to be the scalar and tensor $cs\bar{c}\bar{s}$ tetraquark states, respectively, and study them with the QCD sum rules. In

Understanding the $0^{++}$ and $2^{++}$ charmonium(-like) states near 3.9 GeV

We propose that the X (3915) observed in the J/ψ ω channel is the same state as the χ c 2 (3930), and the X (3960), observed in the D + s D − s channel, is an S -wave D + s D − s hadronic molecule.

Mixed Charmonium-Molecule Interpretation for the Y (3940) State

QCD sum rules are used to study the mass and the decay widths of the Y(3940) state. We assume that it can be described by a mixed charmonium-molecule scalar current with JPC = 0++. Using a mixing

Analysis of the Y(4140) with QCD sum rules

AbstractIn this article, we assume that there exists a scalar $D_{s}^{\ast}{\bar{D}}_{s}^{\ast}$ molecular state in the J/ψφ invariant mass distribution, and we study its mass using the QCD sum

Diquark-Antidiquark Interpretation of Mesons

We study the spectroscopy of the states which defy conventional $c\bar{c}$ charmonium and $b\bar{b}$ bottomonium interpretation respectively, and are termed as exotic states. In August 2003 a state

NEW HADRON STATES

In the past four years we have witnessed the renaissance of the hadron spectroscopy. Many interesting new hadron states were discovered experimentally, some of which do not fit into the quark model

Observation of a near-threshold omegaJ/psi mass enhancement in exclusive B-->KomegaJ/psi decays.

The observation of a near-threshold enhancement in the omegaJ/psi invariant mass distribution for exclusive B-->KomegaJ/PSi decays is reported and is estimated to be greater than 8sigma.
