Enhanced Soft Limits in de Sitter Space
Connor Armstrong, Arthur Lipstein, Jiajie Mei
In flat space, the scattering amplitudes of certain scalar effective field theories exhibit enhanced soft limits due to the presence of hidden symmetries. In this paper, we show th…
New recursions for tree-level correlators in (Anti) de Sitter space
Connor Armstrong, Humberto Gomez, Renann Lipinski Jusinskas +2
We present for the first time classical multiparticle solutions in Anti de Sitter space (AdS) involving scalars, gluons, and gravitons. They are recursively defined through multipa…
Effective Field Theories and Cosmological Scattering Equations
Connor Armstrong, Humberto Gomez, Renann Lipinski Jusinskas +2
We propose worldsheet formulae for wavefunction coefficients of the massive non-linear sigma model (NLSM), scalar Dirac-Born-Infeld (DBI), and special Galileon (sGal) theories in d…
