Infrared-Finite Positivity Bounds in 4D Gravity
Ziyu Dong
We formulate an S-matrix bootstrap in an exactly flat half-space, where boundary reflection provides geometric infrared control for four-dimensional gravity. Under the channel posi…
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…
Bootstrapping the Chiral-Gravitational Anomaly
Zi-Yu Dong, Teng Ma, Alex Pomarol +1
We analyze causality and unitarity constraints in graviton scattering amplitudes, aiming to establish new bounds on theories with -gravitational anomalies, such as axion mode…
The New Formulation of Higgs Effective Field Theory
Zi-Yu Dong, Teng Ma, Jing Shu +1
We present the explicit construction of the effective field theory (EFT) of standard model mass eigenstates. The EFT, which is invariant under , i…
Dressed vs. Pairwise States, and the Geometric Phase of Monopoles and Charges
Csaba Csáki, Zi-Yu Dong, Ofri Telem +2
We construct the Faddeev-Kulish dressed multiparticle states of electrically and magnetically charged particles, incorporating the effects of real and virtual soft photons. We calc…
Constructing Generic Effective Field Theory for All Masses and Spins
Zi-Yu Dong, Teng Ma, Jing Shu +1
We fully solve the long-standing problem of operator basis construction for fields with any masses and spins. Based on the on-shell method, we propose a novel method to systematica…
Constructing on-shell operator basis for all masses and spins
Zi-Yu Dong, Teng Ma, Jing Shu
We first propose a general method to construct the complete set of on-shell operator bases involving massive particles with any spins. To incorporate the non-abelian little groups…
UV Completed Composite Higgs model with heavy composite partners
Zi-Yu Dong, Cong-Sen Guan, Teng Ma +2
We study electroweak symmetry breaking in minimal composite Higgs models with purely fermionic UV completions based on a confining Hypercolor gauge group and find tha…
