Cutting rule for in-in correlators and cosmological collider
Yohei Ema, Kyohei Mukaida
We derive a cutting rule for equal-time in-in correlators including cosmological correlators based on Keldysh basis, which decomposes diagrams into fully retarded functions a…
Momentum shift and on-shell recursion relation for electroweak theory
Yohei Ema, Ting Gao, Wenqi Ke +3
We study the All-Line Transverse (ALT) shift which we developed for on-shell recursion of amplitudes for particles of any mass. We discuss the validity of the shift for general the…
Chiral properties of the nucleon interpolating current and -dependent observables
Yohei Ema, Ting Gao, Maxim Pospelov +1
We revisit the chiral properties of nucleon interpolating currents, and show that of the two leading order currents and , only two linear combinations trans…
Dark Matter Catalyzed Baryon Destruction
Yohei Ema, Robert McGehee, Maxim Pospelov +1
WIMP-type dark matter may have additional interactions that break baryon number, leading to induced nucleon decays which are subject to direct experimental constraints from proton…
Inflaton decay in No-Scale Supergravity and Starobinsky-like models
Yohei Ema, Marcos A. G. Garcia, Wenqi Ke +2
We consider the decay of the inflaton in Starobinsky-like models arising from either an theory of gravity or no-scale supergravity models. If Standard Model matter is…
Momentum shift and on-shell constructible massive amplitudes
Yohei Ema, Ting Gao, Wenqi Ke +3
We construct tree-level amplitude for massive particles using on-shell recursion relations based on two classes of momentum shifts: an all-line transverse shift that deforms moment…
Probing Earth-Bound Dark Matter with Nuclear Reactors
Yohei Ema, Maxim Pospelov, Anupam Ray
Strongly-interacting dark matter can be accumulated in large quantities inside the Earth, and for dark matter particles in a few GeV mass range, it can exist in large quantities ne…
