Stochastic Inflation at NNLO
Timothy Cohen, Daniel Green, Akhil Premkumar +1
Stochastic Inflation is an important framework for understanding the physics of de Sitter space and the phenomenology of inflation. In the leading approximation, this approach resu…
Soft de Sitter Effective Theory
Timothy Cohen, Daniel Green
Calculating the quantum evolution of a de Sitter universe on superhorizon scales is notoriously difficult. To address this challenge, we introduce the Soft de Sitter Effective Theo…
Circumnavigating Collinear Superspace
Timothy Cohen, Gilly Elor, Andrew J. Larkoski +1
In this paper, we extend the collinear superspace formalism to include the full range of supersymmetric interactions. Building on the effective field theory rules…
Navigating Collinear Superspace
Timothy Cohen, Gilly Elor, Andrew J. Larkoski +1
We introduce a new set of effective field theory rules for constructing Lagrangians with supersymmetry in collinear superspace. In the standard superspace treatme…
Collinear Superspace
Timothy Cohen, Gilly Elor, Andrew J. Larkoski
This letter provides a superfield based approach to constructing a collinear slice of = 1 superspace. The strategy is analogous to integrating out anti-collinear ferm…
On-shell constructibility of tree amplitudes in general field theories
Timothy Cohen, Henriette Elvang, Michael Kiermaier
We study "on-shell constructibility" of tree amplitudes from recursion relations in general 4-dimensional local field theories with any type of particles, both massless and massive…
