Vacuum polarization for compactified $QE{D}_{4+1}$ in a magnetic flux background

C. Ccapa Tira, C. D. Fosco, A. P. C. Malbouisson +1

We evaluate one-loop effects for $QE{D}_{4+1}$ compactified to ${\mathbf{R}}^4\times S^1$, in a non-trivial vacuum for the gauge field, such that a non-vanishing magnetic flux is encircl…
