The Yukawa potential: from Quantum Mechanics to Quantum Field Theory

Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Curs: 2019, Tutor: Josep Taron RocaQuantum Mechanics and Quantum Field Theory treatment for the scattering of two fermions is compared to find out an instantaneous effective Yukawa potential describing the interaction in the non relativistic limit. The comparison is made between the S matrix element for the scattering of 2 particles in time independent QM and the non relativistic limit of the scattering amplitude of 2 fermions due to a Yukawa interaction in QF
