On-shell recursion relations for higher-spin Compton amplitudes
Yohei Ema, Ting Gao, Wenqi Ke +2
We recursively construct tree-level electromagnetic and gravitational Compton amplitudes of higher-spin massive particles by the all-line transverse momentum shift. With three-poin…

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…

Unitarity constraint on the Kähler curvature
Yohei Ema, Ryuichiro Kitano, Takahiro Terada
In supersymmetric theories, the signs of quartic terms in the Kähler potential control the stability of non-supersymmetric field configurations. In particular, in supersymmetric in…
