We examine the gauge invariance of massive vector Kaluza-Klein(KK)modes within various 6D brane models.Our analysis reveals that additional constraints on the brane geometry are essential to maintain the gauge invaria...

In this work,we investigate the numerical evolution of massive Kaluza–Klein(KK)modes of a Dirac field on a thick brane.We deduce the Dirac equation in five-dimensional spacetime,and obtain the time-dependent evolutio...
In this study,we investigate ModMax electrodynamics localized within the Randall-Sundrum Ⅱ and Dvali-Gabadadze-Porrati branes,deriving corresponding 3-brane spacetime solutions that conform to the effective Einstein ...

We study a charged Taub-NUT spacetime solution in the Dvali-Gabadadze-Porrati (DGP) brane. We show that the Reissner-Nordstrom-Taub-NUT-de Sitter solution of Einstein-Maxwell gravity solves the corresponding equations...

We investigate the construction of four-family N= 1 supersymmetric Pati-Salam models from Type IIA T^(6)×Z_(2) Z_(2) orientifold with intersecting D6-branes. Utilizing the deterministic algorithm introduced in He W, ...
Based on a comprehensive review of mainly the non-quantum aspects of the standard model of cosmology, the 5 dimensional models, and the analysis here, we propose a 5 dimensional model with expanding 4D multi-branes. A...
