Functional integral method for potential scattering amplitude in quantum mechanics
Cao Thi Vi Ba, Do Thu Ha, Nguyen Nhu Xuan
The functional integral method can be used in quantum mechanics to find the scattering amplitude for particles in the external field. We will obtain the potential scattering amplit…

The contribution of effective quantum gravity to the high energy scattering in the framework of modified perturbation theory and one loop approximation
Nguyen Suan Han, Do Thu Ha, Nguyen Nhu Xuan
The asymptotic behavior of the scattering amplitude for two scalar particles at high energies with fixed momentum transfers is studied. The study is done within the effective theor…
