Interpretation of Scalar and axial mesons in LHCb from an historical perspective
F. E. Close, A. Kirk
LHCb measurements of are shown to be consistent with historical data on scalar and axial mesons below 2 GeV. This is in contrast to some recent interpretations…
Novel Charmonium and Bottomonium Spectroscopies due to Deeply Bound Hadronic Molecules from Single Pion Exchange
Frank Close, Clark Downum, Christopher E. Thomas
Pion exchange in S-wave between hadrons that are themselves in a relative S-wave is shown to shift energies by hundreds of MeV, leading to deeply bound quasi-molecular states. In t…
On the possibility of Deeply Bound Hadronic Molecules from single Pion Exchange
Frank Close, Clark Downum
Pion exchange in S-wave between hadrons that are themselves in a relative S-wave can shift energies by hundreds of MeV. In the case of charmed mesons a spectroscopy…
Charmonium production in e+e- to ψ+ X(c\bar c) and e+e- to D*D_J
Frank Close, Clark Downum
The dominance of chi_0 in the data for e+e- to psi + chi_J(c\bar{c}) is shown to violate OZI factorization. Single gluon exchange gives a non-factorizing effective S.L interaction…
Is X(3872) a molecule?
C. E. Thomas, F. E. Close
We show that the literature on pion exchange between charm and bottom mesons is inconsistent. We derive the formalism explicitly, expose differences between papers in the literatur…
Search for tetraquark candidate Z(4430) in meson photoproduction
Xiao-Hai Liu, Qiang Zhao, Frank E. Close
We propose a search for the newly discovered tetraquark candidate Z(4430) in photoproduction. Based on the Belle results we show that if Z(4430) is a genuine resonance, its signifi…
