    Double parton correlations in mesons within AdS/QCD soft-wall models: a first comparison with lattice data

    No full text
    Double parton distribution functions (dPDFs), entering the double parton scattering (DPS) cross section, are unknown fundamental quantities encoding new interesting properties of hadrons. Here, the pion dPDFs are investigated within different holographic QCD quark models in order to access their basic features. Results of the calculations obtained within the AdS/QCD soft-wall approach, have been compared with predictions of lattice QCD evaluations of the pion two-current correlation functions. The present analysis confirms that double parton correlations, affecting dPDFs, are very important and not direct accessible from generalised parton distribution functions and electromagnetic form factors. The comparison between lattice data and quark model calculations unveils the relevance of the contributions of high partonic Fock states in the pion. Nevertheless, by using a complete general procedure, results of lattice QCD have been used, for the first time, to estimate the mean value of the so called σeff\sigma _{eff}, a relevant experimental observable for DPS processes. In addition, the results of the first calculations of the ρ\rho meson dPDFs are discussed in order to make predictions

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Physiological parameters predicting the outcome of surgical and nonsurgical treatment of fecal incontinence

    Fecal incontinence is a multifactorial disease. Anorectal physiology studies play an outstanding role in the evaluation of its etiology and severity, the two main factors that constitute the basis for the correct choice of treatment. However, the prognostic role of clinical factors and anorectal physiological tests in predicting the outcome to either conservative or surgical treatment is questionable. © 2007 Springer-Verlag Italia
