| contents | Rise and fall of pentaquarks in the QCD Sum Rules approach R. D. Matheus F. S. Navarra M. Nielsen Física, Astronomía y Matemáticas Pentaquarks QCD Sum Rules Mass and decay We review the existing mass and decay width determinations of pentaquarks with QCD Sum Rules (QCDSR). We give special attention to the intermediate assumptions and choices which we are obliged to do in this approach. As an example, we present the full calculation of the pentaquark mass with Borel sum rules and also with Finite Energy Sum Rules (FESR). We also work out the calculation of the theta decay width. We take the opportunity to comment our publications on this subject and include new and unpublished material. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413543014 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4b Vol.36 |
