Electroweak Restoration: SMEFT and HEFT
Ian M. Lewis, Zhen Liu, Ishmam Mahbub
Colliders continue to push our understanding of electroweak (EW) interactions to ever higher energies. At high energies, many observables in the broken EW theory are expected to ap…
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…
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…
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…
Top Yukawa Coupling Determination at High Energy Muon Collider
Zhen Liu, Kun-Feng Lyu, Ishmam Mahbub +1
The Top Yukawa coupling profoundly influences several core mysteries linked to the electroweak scale and the Higgs boson. We study the feasibility of measuring the Top Yukawa coupl…
