Explicit Conditions for Diagnosing Tree-Level Unitarity
Jaehoon Jeong, Pyungwon Ko, Yu-Hui Zheng
We explicitly present all coupling conditions required for tree-level unitarity (tree unitarity) in theories with a finite number of massive and massless particles of spin up to 1.…
No gauge cancellation at high energy in the five-vector gauge
Jaehoon Jeong
We propose a novel gauge in the five-vector (5V) framework within the Abelian Higgs model. In the Cartesian basis of the complex Higgs field, the 5V gauge ensures non-d…
Vetoing all the Higgs imposters in
Seong Youl Choi, Jaehoon Jeong, Dong Woo Kang
We develop an effective and methodical algorithm for the construction of general covariant four-point vertices, accommodating leptons , and designed to han…
Hunting for Hypercharge Anapole Dark Matter in All Spin Scenarios
Seong Youl Choi, Jaehoon Jeong, Dong Woo Kang +1
We conduct a combined analysis to investigate dark matter (DM) with hypercharge anapole moments, focusing on scenarios where Majorana DM particles with spin 1/2, 1, 3/2, and 2 inte…
