    Many other factors affecting citation of publications, except for research area coverage, have been studied. This study aims to investigate impact of research area coverage. Bibliometric papers and their related papers (referred papers, citing papers and first author's papers) were screened and matched by Python program. Papers' research areas were classified according to Web of Science. Bibliometric parameters of the most cited 5% and the least cited 5% papers were compared. Firstly, coverage of related papers' research areas impacts the citation of their original papers. The impact of references and citing papers are positive and negative, separately, while the first author's papers have no influence. Secondly, high-influence papers tend to cite references from a wider area and are cited by followers from a wider area. Additionally, the pattern of knowledge flow differs significantly between high- and low-influence papers. Low-influence papers narrow knowledge flow, whereas high-influence papers broaden it. This study has shown that both depth and breadth of research area coverage can influence citations. It is recommended that authors should extensively cite high-influence publications, both within and beyond their own area

    The productions of the exotic states X0(2900) X_0(2900) and X1(2900) X_1(2900) in K+pβ†’Ξ£c++X0(2900)K^{+}p \to \Sigma_{c}^{++}X_{0}(2900) and K+pβ†’Ξ£c++X1(2900)K^{+}p \to \Sigma_{c}^{++}X_{1}(2900) reactions are studied within an effective Lagrangian approach. The tβˆ’t-channel Born term is included to calculate the production cross sections. The numerical results show that the total cross section may reach up to about 0.5 nb and 25 nb for the production of X0(2900) X_0(2900) and X1(2900) X_1(2900) , respectively. The predicted differential cross sections are sensitive to the scattering angles and have strong forward enhancements. The cross sections for the K+nβ†’Ξ›c+X0,1K^{+}n \to \Lambda_{c}^{+}X_{0,1} are also calculated and found to be larger than that in K+pK^{+}p collisions by more than one order of magnitude. The results are helpful to the possible experiments at J-PARC and COMPASS.Comment: 5 pages, 5 figure
