The Role of the Curvaton Post-Planck
Gongjun Choi, Wenqi Ke, Keith A. Olive
The expected improvements in the precision of inflationary physics observables including the scalar spectral index and the tensor-to-scalar ratio will reveal more than…
Effective interactions and on-shell recursion relation for massive spin 3/2
Tony Gherghetta, Wenqi Ke
We use on-shell methods to compute all three-point interactions of massive spin-3/2 particles involving a graviton and particles of spin . By employing the massive spinor-h…
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…
Charged massive spin 2 and 3/2 propagation in a constant electromagnetic background
Karim Benakli, Wenqi Ke, Bruno Le Floch
We present two methods for deriving the equations of motion for charged massive spin-3/2 particles. The first approach involves utilizing the Euler-Lagrange equations derived from…
Inflaton Production of Scalar Dark Matter through Fluctuations and Scattering
Gongjun Choi, Marcos A. G. Garcia, Wenqi Ke +3
We study the effects on particle production of a Planck-suppressed coupling between the inflaton and a scalar dark matter candidate, . In the absence of this coupling, the domin…
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…
Minimal Production of Prompt Gravitational Waves during Reheating
Gongjun Choi, Wenqi Ke, Keith A. Olive
The inflationary reheating phase begins when accelerated expansion ends. As all Standard Model particles are coupled to gravity, gravitational interactions will lead to particle pr…
