- Sewing string tree vertices with ghosts Leonidas Sandoval Junior Física, Astronomía y Matemáticas It is shown how to sew string vertices with ghosts at tree level in order to produce new tree vertices using the Group Theoretic approach to String Theory. It is then verified the BRST invariance of the sewn vertex and shown that it has the correct ghost number. 2002 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413503035 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.1 Vol.32
