Can 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 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 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...
متن کاملCan Shaker Potassium Channels be Locked in the Deactivated State?
For structural studies it would be useful to constrain the voltage sensor of a voltage-gated channel in its deactivated state. Here we consider one Shaker potassium channel mutant and speculate about others that might allow the channel to remain deactivated at zero membrane potential. Ionic and gating currents of F370C Shaker, expressed in Xenopus oocytes, were recorded in patches with internal...
متن کاملSuperconducting properties of the s ±-wave state: Fe-based superconductors.
Although the pairing mechanism of Fe-based superconductors (FeSCs) has not yet been settled with consensus with regard to the pairing symmetry and the superconducting (SC) gap function, the vast majority of experiments support the existence of spin-singlet sign-changing s-wave SC gaps on multi-bands ([Formula: see text]-wave state). This multi-band [Formula: see text]-wave state is a very uniqu...
