Static-Recoil Factorization in Heavy-Baryon Chiral EFTs
Ziyu Dong, Teng Ma, Chengjie Yang +1
Extending heavy-baryon \(χ\)PT to higher-spin resonances introduces unphysical lower-spin admixtures, leading to costly path-integral projections. To resolve this, we develop an on…

Heavy Long-lived Dark Vector Via a Gluonic Portal
Xiaoyong Chu, Qiyuan Gao, Hongkai Liu +2
We study a dark gauge boson that exclusively couples to the QCD gluons through higher dimensional operators. These operators are generated from integrating out of heavy ultr…

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…
