Astrophysical Graviton Squeezing Can Be Hidden in the Far-Field
Cheng-Jun Fang, Zong-Kuan Guo, Zhen-Hong Lyu +3
While localized astrophysical sources can generate macroscopic graviton squeezing, their observable quantum signatures at far-field detectors remain unresolved. In this work, we in…
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…
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…
