Abstract

We developed a nonperturbative technique in field theory to obtain the ground state properties of 4 He nucleus. Here, the σ-meson effects are simulated through isosinglet scalar cloud of pairs of off-shell pions with a coherent state. The analysis de facto replaces the scalar isoscalar potential in nuclear physics by multipion condensates. Also, we discuss the two hard photons production from the off-shell π+π− pair as present through pion cloud within the framework of the model.
