Bounds on nonlinear electrodynamics via resummed relative entropy
Pietro Conzinu, Daiki Ueda
We investigate nonlinear electrodynamic effective field theories (EFTs) through the relative entropy evaluated in suitable background electromagnetic fields. In this setup, the rel…
Bounds on nonlinear effective field theories via resurgent relative entropy
Pietro Conzinu, Daiki Ueda
We study nonlinear effective field theories (EFTs) with factorially growing perturbative expansions, focusing on a class in which the relative entropy encodes an infinite tower of…
The Spurion Massive EFT (SMEFT)
Julian L. Northey, Yael Shadmi, Yotam Soreq +1
We use the amplitude formulation of the SMEFT to introduce a spurion analysis of the SMEFT low-energy amplitudes in terms of the Higgs VEV. Each SMEFT contact-term is given as a su…
Muon collider experiments as electron/positron beam sources: case studies of new light-particle searches
Yasuhito Sakaki, Daiki Ueda
At muon colliders, muon decays naturally produce intense electrons and positrons with unique features, namely high energies, high repetition rates, and small intrinsic uncertaintie…
Quantum Resonance Beyond Direct Measurement: Insights from Weak Measurement
Daiki Ueda, Izumi Tsutsui
Aharonov's weak value amplification realized via weak measurement provides a versatile means to measure physical parameters with high accuracy, similar to quantum resonance epitomi…
RGE effects on new physics searches via gravitational waves
Katsuya Hashino, Daiki Ueda
Gravitational wave (GW) observations offer a promising probe of new physics associated with a first-order electroweak phase transition. Precision studies of the Higgs potential, in…
