Probing Scalar Effective Field Theories with the Soft Limits of Scattering Amplitudes

Antonio Padilla, David Stefanyszyn, Toby Wilson

We investigate the soft behaviour of scalar effective field theories (EFTs) when there is a number of distinct derivative power counting parameters, $ρ_{1} < ρ_{2} < \dots < ρ_{Q}$ . We cla…

Sequestering effects on and of vacuum decay

Nemanja Kaloper, Antonio Padilla, David Stefanyszyn

We consider phase transitions and their contributions to vacuum energy in the manifestly local theory of vacuum energy sequestering. We demonstrate that the absence of instabilitie…
