Study of with unitarized coupled channel scattering amplitudes
Full text linkIn this paper, we study the resonant state . The scattering
amplitudes of coupled channels, --, are constructed with the interaction of four vector mesons
described by effective Lagrangians. The amplitudes are calculated up to one
loop, decomposed by partial wave projection, and unitarized by Pad
approximation. These amplitudes are fitted to the latest experimental data sets
of di- and invariant mass spectra of LHCb, CMS, and
ATLAS. High-quality solutions are obtained. With these partial wave amplitudes,
we extract the pole parameters of the . Its quantum number is likely
to be . According to the pole counting rule as well as analysis of the
phase shifts of the partial waves, it supports our previous conclusion that the
prefers to be a compact tetra-quark.Comment: 23 pages, 4 figures, add a few discussion
Nature of and its production mechanism at LHCb
No full textWe show that the Pomeron exchanges play a unique role in vector charmonium scatterings. Such a mechanism can provide a natural explanation for the nontrivial structures in the di-J/ψ spectrum observed by the LHCb Collaboration. The narrow structure X(6900), as a dynamically generated resonance pole, can arise from the Pomeron exchanges and coupled-channel effects between the J/ψ-J/ψ, J/ψ-ψ(2S) scatterings. A pole structure near the di-J/ψ threshold is also found. Meanwhile, we predict that X(6900) can produce significant threshold enhancement in the J/ψ-ψ(2S) energy spectrum which can be searched for at LHCb.We show that the Pomeron exchanges play a unique role in vector charmonium scatterings.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Discovery potential for the LHCb fully-charm tetraquark state via annihilation reaction
No full textInspired by the observation of the fully-charm tetraquark state at LHCb, the production of in reaction is studied within an effective Lagrangian approach and Breit-Wigner formula. The numerical results show that the cross section of at the c.m. energy of 6.9 GeV is much larger than that from the background contribution. Moreover, we estimate dozens of signal events can be detected by D0 experiment, which indicates that searching for the via antiproton-proton scattering may be a very important and promising way. Therefore, related experiments are suggested to be carried out
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
