I. C. Jardim, G. Alencar, R. R. Landim, R. N. Costa Filho
TL;DR
This paper critically examines previous claims about the localization of ELKO spinor zero modes on Minkowski branes, demonstrating that earlier results were incorrect and highlighting the need to revisit the localization problem.
Contribution
The paper refutes prior assertions of ELKO zero mode localization on thin branes, clarifying the issue and prompting further investigation into ELKO spinor localization mechanisms.
Findings
Previous claims of ELKO zero mode localization are incorrect
The localization of ELKO spinors on Minkowski branes remains unresolved
The paper emphasizes the need for revised models or conditions for localization
Abstract
We show that the statement in Yu-Xiao Liu, Xiang-Nan Zhou, Ke Yang and Feng-Wei Chen [Phys. Rev. D 86 , 064012 (2012)] that the zero mode of ELKO spinor is localized in some thin brane scenarios is not correct. This reopens the problem of localization of ELKO spinors.
