Albert Albiol, Elvira ; Arenas Sánchez, Purificación ; Genaim, Samir ; Puebla, Germán ; Román Díez, Guillermo | Elsevier | 2014-10Static analysis which takes into account the values of data stored in the heap is considered complex and computationally intractable in practice. Thus, most static analyzers do not keep track of object fields nor of array contents, i.e., they ar[...]texto impreso

We present a model in which a hadron is represented as a bound state of several nonlinear Dirac fields which we identify with the quarks. These fields interact by a fourth order coupling term. We define a particle as any finite energy solitary w[...]texto impreso
