Kalb–Ramond field localization on the Bloch brane
This work deals with new results on the Kalb-Ramond (KR) field localization
in braneworld models. We consider a five-dimensional warped spacetime with an
embedded 4D thick brane which is generated by two real scalar fields coupled
with gravity (the so called Bloch brane). We find a KR field zero mode
localized with the inclusion of the dilaton coupling. Analyzing the massive
spectrum, we detected a series of resonant modes that arise from the solutions
of the Schr\"odinger-like equation for KR field. The effects of the brane
thickness and of the dilaton coupling over the resonance structures are
determined. Such analysis is extended to the resonance lifetimes of the massive
modes, allowing a better understanding on the localization mechanism of the
model.Comment: 18 pages, 6 figure
