The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

Despite the apparent simplicity of meson spectroscopy there are some states which cannot be accommodated in the usual $q\bar q$ structure. Among them there are either exotic states as the X(1600) or the recently measured charm states $D_{sJ}^*$ and X(3872) and some of the light scalar mesons. In this work we present a possible description of these states in terms of tetraquarks.

The paper

Original abstract

Despite the apparent simplicity of meson spectroscopy there are some states which cannot be accommodated in the usual $q\bar q$ structure. Among them there are either exotic states as the X(1600) or the recently measured charm states $D_{sJ}^*$ and X(3872) and some of the light scalar mesons. In this work we present a possible description of these states in terms of tetraquarks.

Pion Interactions in the X(3872)
hep-ph 2007-03 accept novelty 6.0 of 10

Pion exchange in the X(3872) molecule is perturbative, and the resulting next-to-leading correction to the D0 anti-D0 pi0 decay width is dominated by short-distance contact terms rather than by pions.
Estimate for the X(3872) to gamma J/psi decay width
hep-ph 2008-02 conditional novelty 4.0 of 10

Assuming X(3872) is a D0-D*0 molecule, a one-loop calculation gives a photon-plus-J/psi decay width of 125 to 250 keV, and a charmonium admixture is found to reduce rather than enhance the rate.

1 arXiv paper cite this in 1 sentence

Each citing sentence is taken from the citing paper's LaTeX source and typed by Pith's classifier. A label appears at probability 0.8 or more (0.95 for support), a contest at 0.7 or more; the quoted words are the citing authors'. How each label was checked · JSON
