Weak Field Limit for Embedding Gravity

Universe, 2022
We study a perturbation theory for embedding gravity equations in a background for which corrections to the embedding function are linear with respect to corrections to the flat metric.

Development of High-Granularity Dual-Readout Calorimetry with psec Timing [PDF]

EPJ Web of Conferences
Dual-readout and particle flow algorithm (PFA) are technologies proposed for precise jet energy measurement in future colliders. While PFA requires highly granular calorimeters, dual-readout has mainly been used with fiber-based calorimeters that do not ...

On the dynamical origin of the η ′ potential and the axion mass

Journal of High Energy Physics, 2023
We investigate the dynamics responsible for generating the potential of the η ′ , the (would-be) Goldstone boson associated with the anomalous axial U(1) symmetry of QCD.

Naturalness sum rules and their collider tests

Journal of High Energy Physics, 2019
We present the most general sum rules reflecting the cancellation of ultraviolet divergences in the Higgs potential, which provide necessary conditions for any weakly-coupled extension of the Standard Model to be natural. There is a separate sum rule for

Strip-based Scintillation Detector for Dual-readout High-granularity Calorimetry [PDF]

EPJ Web of Conferences
New calorimeter technology is being developed for future collider experiments. We are developing a calorimeter that integrates two technologies, a high-granularity calorimeter and a dual-readout calorimeter, and has high time resolution at a picosecond ...
