Well-Tempered Cosmology
William T. Emond, Chunhao Li, Paul M. Saffin +1
We examine an approach to cosmology, known as Well-Tempering, that allows for a de Sitter phase whose expansion is independent of the cosmological constant. Starting from a generic…
Positivity bounds on vector boson scattering at the LHC
Cen Zhang, Shuang-Yong Zhou
Weak vector boson scattering (VBS) is a sensitive probe of new physics effects in the electroweak symmetry breaking. Currently, experimental results at the LHC are interpreted in t…
Positivity Bounds for Massive Spin-1 and Spin-2 Fields
Claudia de Rham, Scott Melville, Andrew J. Tolley +1
We apply the recently developed positivity bounds for particles with spin, applied away from the forward limit, to the low energy effective theories of massive spin-1 and spin-2 th…
Gravitational waves from asymmetric oscillon dynamics?
Mustafa A. Amin, Jonathan Braden, Edmund J. Copeland +4
It has been recently suggested that oscillons produced in the early universe from certain asymmetric potentials continue to emit gravitational waves for a number of -folds of ex…
Are gravitational wave ringdown echoes always equal-interval ?
Yu-Tong Wang, Zhi-Peng Li, Jun Zhang +2
Gravitational wave (GW) ringdown waveforms may contain "echoes" that encode new physics in the strong gravity regime. It is commonly assumed that the new physics gives rise to the…
