On perturbative scattering amplitudes in maximally supersymmetric theories [PDF]

open access: yes, 2011
PhDThere has been substantial calculational progress in the last few years in maximally supersymmetric theories, revealing unexpected simplicity, new structures and symmetries. In this thesis, after reviewing some of the recent advances in N = 4 super

Navigating collinear superspace

open access: yesJournal of High Energy Physics, 2020
We introduce a new set of effective field theory rules for constructing Lagrangians with N $$ \mathcal{N} $$ = 1 supersymmetry in collinear superspace. In the standard superspace treatment, superfields are functions of the coordinates x μ θ α θ † α ⋅ $$ \

Ghostbusters: unitarity and causality of non-equilibrium effective field theories

open access: yesJournal of High Energy Physics, 2020
: For a non-equilibrium physical system defined along a closed time path (CTP), a key constraint is the so-called largest time equation, which is a consequence of unitarity and implies causality.

Topological couplings in higher derivative extensions of supersymmetric three-form gauge theories

open access: yesJournal of High Energy Physics, 2019
We consider a topological coupling between a pseudo-scalar field and a 3- form gauge field in N = 1 $$ \mathcal{N}=1 $$ supersymmetric higher derivative 3-form gauge theories in four spacetime dimensions. We show that ghost/tachyon-free higher derivative

Swampland constraints on 5d N $$ \mathcal{N} $$ = 1 supergravity

open access: yesJournal of High Energy Physics, 2020
We propose Swampland constraints on consistent 5-dimensional N $$ \mathcal{N} $$ = 1 supergravity theories. We focus on a special class of BPS magnetic monopole strings which arise in gravitational theories.

Interaction of supersymmetric nonlinear sigma models with external higher spin superfields via higher spin supercurrents

open access: yesJournal of High Energy Physics, 2018
We consider a four dimensional generalized Wess-Zumino model formulated in terms of an arbitrary Kähler potential KΦΦ¯ $$ \mathcal{K}\left(\varPhi, \overline{\varPhi}\right) $$ and an arbitrary chiral superpotential WΦ $$ \mathcal{W}\left(\varPhi \right)

Hidden U(N) symmetry behind N $$ \mathcal{N} $$ = 1 superamplitudes

open access: yesJournal of High Energy Physics, 2023
In this paper we develop a Young diagram approach to constructing higher dimensional operators formed from massless superfields and their superderivatives in N $$ \mathcal{N} $$ = 1 supersymmetry. These operators are in one-to-one correspondence with non-

Globally and locally supersymmetric effective theories for light fields [PDF]

open access: yes, 2009
We reconsider the general question of how to characterize most efficiently the low-energy effective theory obtained by integrating out heavy modes in globally and locally supersymmetric theories. We consider theories with chiral and vector multiplets and

Higher derivative three-form gauge theories and their supersymmetric extension

open access: yesJournal of High Energy Physics, 2018
We investigate three-form gauge theories with higher derivative interactions and their supersymmetric extensions in four space-time dimensions. For the bosonic three-form gauge theories, we show that derivatives on the field strength of the 3-form gauge ...

Currents in supersymmetric field theories [PDF]

open access: yes, 2016
A general formalism to construct and improve supercurrents and source or anomaly superfields in two-derivative N = 1 supersymmetric theories is presented. It includes arbitrary gauge and chiral superfields and a linear superfield coupled to gauge fields.
