We calculate the branching ratio for the production of the meson $Y(4260)$ in the decay $B^- \to Y(4260)K^-$. We use QCD sum rules approach and we consider the $Y(4260)$ to be a mixture between charmonium and exotic tetraquark, $[\bar{c}\bar{q}][qc]$, states with $J^{PC}=1^{--}$. Using the value of the mixing angle determined previously as: $\theta=(53.0\pm0.5)^\circ$, we get the branching ratio $\mathcal{B}(B\to Y(4260)K)=(1.34\pm0.47)\times10^{-6}$, which allows us to estimate an interval on…

QCD sum rules study of the J(PC) = 1-- charmonium Y mesons
We use QCD sum rules to test the nature of the recently observed mesons Y(4260), Y(4350) and Y(4660), assumed to be exotic four-quark $(c\bar{c}q\bar{q})$ or $(c\bar{c}s\bar{s})$ states with
Exotic $1^{--}$ States in QCD Sum Rules
Using the QCD sum rules we test if the charmonium-like structure Y(4260), observed in the $J/\psi\pi\pi$ invariant mass spectrum, can be described with a $J/\psi f_0(980)$ molecular current with
QCD sum rules for the X ( 3872 ) as a mixed molecule-charmonium state
We use QCD sum rules to test the nature of the meson $X(3872)$, assumed to be a mixture between charmonium and exotic molecular $[c\overline{q}][q\overline{c}]$ states with
Four quark interpretation of Y(4260)
We propose that the $Y(4260)$ particle recently announced by BABAR is the first orbital excitation of a diquark-antidiquark state $([cs][\overline{c}\overline{s}])$. Using parameters recently
Y(4260) as a mixed charmonium-tetraquark state
Using the QCD sum rule approach we study the Y(4260) state assuming that it can be described by a mixed charmonium-tetraquark current with $J^{PC}=1^{--}$ quantum numbers. For the mixing angle around
Could Yb(10890) be the P-wave $ [bq][\bar{b}\bar{q}] $ tetraquark state?
Assuming Yb(10890) as a P-wave bq-scalar-diquark $ \bar{b}\bar{q} $-scalar-antidiquark tetraquark state, the mass of Yb(10890) is computed in the framework of QCD sum rule method. Technically,
Radiative decay of the X(3872) as a mixed molecule-charmonium state in QCD Sum Rules
We use QCD sum rules (QCDSR) to calculate the width of the radiative decay of the meson X(3872), assumed to be a mixture between charmonium and exotic molecular [cq][qc] states with J{sup PC}=1{sup
QCD sum rules for the production of the X(3872) as a mixed molecule-charmonium state in B meson decay
Abstract We use QCD sum rules to calculate the branching ratio for the production of the meson X ( 3872 ) in the decay B → X ( 3872 ) K , assumed to be a mixture between charmonium and exotic

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
Interference effects in the X(4260) signal
We show that the long known puzzling branching ratios of open-charm decays in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation can be reasonably described with a simple form factor, which strongly
