Massive to Massless by Applying a Nonlocal Field Redefinition
Date and time
Tuesday, 14th of Febuary 2023 (25th of Bahman, 1401), 2:00 pm (Tehran zone)
The invariance of physical observables like particle's mass under a local field redefinition is a well-known and important property of the quantum field theory. In this talk, on the other hand, we will discuss invertible nonlocal field redefinitions reducing a massive theory to the massless one, and vice versa. Studied examples would be classical harmonic oscillator, the ...
