Massive gauge field and their accompanying scalars in brane world
Ye-Hao Yang, Wen-Xuan Ma, Chun-E Fu
In brane-world scenarios, the effective action of a massless bulk \(U(1)\) gauge field preserves gauge invariance via couplings between massive vector Kaluza-Klein (KK) modes and s…

Note on hidden zeros and expansions of tree-level amplitudes
Hao Huang, Ye Yang, Kang Zhou
In this note, we derive and interpret hidden zeros of tree-level amplitudes of various theories, including Yang-Mills, non-linear sigma model, special Galileon, Dirac-Born-Infeld,…

Constraints on branes' geometry from massive vector KK modes
Chun-E Fu, Heng Guo, Ye-Hao Yang
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's geometry a…
