Positivity from Cosmological Correlators
Daniel Green, Yiwen Huang, Chia-Hsien Shen +1
Effective field theories in flat space and in anti-de Sitter space are constrained by causality and unitarity, often in the form of positivity bounds. Similar bounds have been hard…
Anharmonic effects in nuclear recoils from sub-GeV dark matter
Tongyan Lin, Chia-Hsien Shen, Mukul Sholapurkar +1
Direct detection experiments are looking for nuclear recoils from scattering of sub-GeV dark matter (DM) in crystals, and have thresholds as low as ~ 10 eV or DM masses of ~ 100 Me…
Scattering Amplitudes, the Tail Effect, and Conservative Binary Dynamics at
Zvi Bern, Julio Parra-Martinez, Radu Roiban +4
We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e. and all orders in velocity, including radiative contributio…
A Periodic Table of Effective Field Theories
Clifford Cheung, Karol Kampf, Jiri Novotny +2
We systematically explore the space of scalar effective field theories (EFTs) consistent with a Lorentz invariant and local S-matrix. To do so we define an EFT classification based…
