Question

I am interested in the problem of bound states in QFT in curved spacetime. I was wondering if the generalization of the Bethe-Salpeter equation is as simple as replacing the Green’s functions in the equation with their curved spacetime counterparts.

Options:
A) Yes, the generalization merely involves replacing the Green’s functions with their curved spacetime counterparts.
B) No, the generalization requires additional modifications beyond replacing the Green’s functions.
C) The generalization can be simplified by only considering modifications to the coupling constants in the Bethe-Salpeter equation.
D) The generalization involves altering the mathematical structure of the Bethe-Salpeter equation beyond a simple replacement of Green’s functions.

Answer 1

No, the generalization of the Bethe-Salpeter equation in curved spacetime requires additional modifications beyond just replacing the Green's functions.

Step-by-step explanation:

No, the generalization of the Bethe-Salpeter equation in curved spacetime requires additional modifications beyond just replacing the Green's functions. In curved spacetime, the equation needs to take into account the effects of spacetime curvature on the interaction between particles. The coupling constants and the mathematical structure of the equation may also need to be modified to accurately describe bound states in this context.
