In this paper, we assign the newly reported state [Formula: see text] to be a [Formula: see text]-wave [Formula: see text] meson, and study its mass and decay constant with QCD sum rules by considering the contributions of vacuum condensates up to dimension-6 in the operator product expansion. The predicted mass [Formula: see text] GeV is in agreement with the experimental data [Formula: see text] MeV from the LHCb collaboration. This result supports assigning [Formula: see text] as the…

Study of the ψ2(3823) and χc1(3872) states in B+ → (J/ψπ+π−)K+ decays

The decays B+ → J/ψπ+π−K+ are studied using a data set corresponding to an integrated luminosity of 9 fb−1 collected with the LHCb detector in proton-proton collisions between 2011 and 2018. Precise

Potential model calculations and predictions for heavy quarkonium

(Dated: February 2, 2008)We investigate the spectroscopy and decays of the charmonium and upsilon systems in a potentialmodel consisting of a relativistic kinetic energy term, a linear confining term

Heavy mesons in a relativistic model.

The authors use the spectator equations to treat the mesonic bound states of heavy quarks and estimate two of the parameters of the heavy quark effective theory, and propose further calculations that may be undertaken in the future.

Molecular charmonium. A new spectroscopy

Using a constituent quark model, we study the mass and decay channels of meson meson and meson baryon structures in the charm sector. We show that the X(3872) and the X(3940) resonances can be

Properties of $D_{s2}^*(2573)$ charmed-strange tensor meson

The mass and current coupling constant of the $D_{s2}^* (2573)$ charmed-strange meson is calculated in the framework of two-point QCD sum rule approach. Although the quantum numbers of this meson is

Analysis of the X(3872), Z c (3900), and Z c (3885) as axial-vector tetraquark states with QCD sum rules

In this article, we distinguish the charge conjunctions of the interpolating currents, calculate the contributions of the vacuum condensates up to dimension 10 in a consistent way in the operator

Properties of P-wave mesons with one heavy quark.

It is found that, even for {ital B} mesons, the tensor interactions play an important role in the spectroscopy and the {ital m}{sub {ital Q}}{r arrow}{infinity} has not yet been reached, and it is concluded that further experimental study of the decay properties of the{ital D}{sub 1} meson is important to the understanding of the mixing mechanism.

Can the X ( 3872 ) be a 1 ++ four-quark state?

We use QCD spectral sum rules to test the nature of the meson X(3872), assumed to be an exotic four-quark (ccqq) state with J{sup PC}=1{sup ++}. For definiteness, we work with the diquark-antidiquark
