Zc(3900) as a tetraquark state: decay width in QCD sum rules
Supposing the Z c (3900) as a charged partner of the X(3872), we use the QCD sum rules techinques in order to obtain the coupling constants of the Z c J/ψ π , Z c ηc ρ + and Z c D D ∗ vertices and the corresponding decay width of these channels. We considered that the Zc(3900) can be described by a tetraquark current with the J = 1 quantum numbers. As a result, we obtained a decay width value i...
متن کامل( 2700 ) a charmed tetraquark state ?
In this article, we take the point of view that the Ds(2700) be a tetraquark state, which consists of a scalar diquark and a vector antidiquark, and calculate its mass with the QCD sum rules. The numerical result indicates that the mass of the vector charmed tetraquark state is about MV = (3.75±0.18)GeV or MV = (3.71 ± 0.15)GeV from different sum rules, which is about 1GeV larger than the exper...
متن کاملCan X(5568) be a tetraquark state?
Very recently, the D0 collaboration has reported the observation of a narrow structure, X(5568), in the decay process X(5568) → B sπ using the 10.4fb−1 data of pp̄ collision at √ s = 1.96 TeV. This structure is of great interest since it is the first hadronic state with four different valence quark flavors, b, s, u, d. In this work, we present a tetraquark interpretation of the X(5568). Based on...
متن کاملSearch for tetraquark candidate Zð4430Þ in meson photoproduction
Frank E. Close Rudolf Peierls Centre for Theoretical Physics, University of Oxford, Keble Road, Oxford, OX1 3NP, United Kingdom (Received 27 February 2008; published 8 May 2008) We propose a search for the newly discovered tetraquark candidate Zð4430Þ in photoproduction. Based on the Belle results, we show that if Zð4430Þ is a genuine resonance, its significantly large coupling to 0 will cause ...
متن کاملIs Ds(2700) a charmed tetraquark state?
In this article, we take the point of view that the Ds(2700) be a tetraquark state, which consists of a scalar diquark and a vector antidiquark, and calculate its mass in the framework of the QCD sum rules approach. The numerical result indicates that the mass of the vector charmed tetraquark state is about MV = 3.75GeV, which is about 1GeV larger than the experimental data. If there are some t...
