چکیده
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 it to stand out above the background in p! Zþð4430Þn! 0 þn. We consider the dependence of the cross section for the quantum numbers (J 1⁄4 1 , 1þ, or 0 ).

THE FLORIDA STATE UNIVERSITY COLLEGE OF ARTS AND SCIENCES SEARCH FOR NEW AND UNUSUAL STRANGEONIA IN PHOTOPRODUCTION USING CLAS By MUKESH
We perform a survey of the proton, K+ , K− 3 charged track data, taken by the CLAS detector for the HyCLAS experiment [1] during the g12 run-period at Jefferson Lab. We aim to study the strong decay amplitudes, partial widths and production channels of strangeonia from the CLAS g12 dataset. HyCLAS was motivated by the experimental results for gluonic hybrid meson candidates, theoretical Lattice...

Considering four-point correlation functions of color-singlet quark bilinears, we investigate, in the largeNc limit of QCD, the subleading diagrams that involve, in the s-channel of meson–meson scattering amplitudes, two-quark–two-antiquark intermediate states. The latter contribute, together with gluon exchanges, to the formation, at the hadronic level, of two-meson and tetraquark intermediate...
متن کاملDecisive search for a diquark-antidiquark meson with hidden strangeness.
Diquark-antidiquark states are expected to exist as a natural complement of mesons and baryons. Although they were predicted long ago, and some candidates were found experimentally, none has, as yet, been reliably identied. We suggest that the search for the so-called C(1480)-meson in reactions such as photoproduction N ! N and KN ! should provide a decisive way to settle this issue. Estimates ...

In this article, we take the point of view that the charmed scalar meson Ds0(2317) be a tetraquark state and devote to calculate its mass within the framework of the QCD sum rules approach in the heavy quark limit. The numerical values for the mass of the Ds0(2317) are consistent with the experimental data, there must be some tetraquark component in the scalar meson Ds0(2317). Detailed discussi...
