Static-Recoil Factorization in Heavy-Baryon Chiral EFTs
Ziyu Dong, Teng Ma, Chengjie Yang +1
The paper introduces a static‑recoil factorization method for heavy‑baryon chiral effective field theory that uses on‑shell recoil‑channel eigenoperators to separate mass and recoi…

An Efficient On-shell Framework for EFT Matching
Ziyu Dong, Cihang Li, Teng Ma +2
Standard techniques for one-loop EFT matching often have gauge and basis redundancies, while strictly 4-dimensional on-shell methods fail to capture rational terms. To resolve this…

Dark Photons and Gravitino Like Particles: Complete EFT Operator Basis
Ziyu Dong, Teng Ma, Chengjie Yang +1
We present a more efficient method for constructing the complete EFT operator basis for particles of any mass and spin, based on on-shell method and Young tableaux. By classifying…
