Superfield Approaches to a Model of Bosonic String: Curci‐Ferrari‐Type Restrictions
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Exploiting the theoretical potential of the modified Bonora‐Tonin superfield approach (MBTSA) as well as the (anti‐)chiral superfield approach (ACSA) to Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we derive the complete set of off‐shell nilpotent (anti‐)BRST symmetry transformations corresponding to the classical two‐ (1 + 1) dimensional (2D ...

Higher spin superfield interactions with complex linear supermultiplet: conserved supercurrents and cubic vertices [PDF]
Journal of High Energy Physics, 2017 We continue the program of constructing cubic interactions between matter and higher spin supermultiplets. In this work we consider a complex linear superfield and we find that it can have cubic interactions only with supermultiplets with propagating ...

Fortschritte der Physik, Volume 69, Issue 11-12, December 2021., 2021 Abstract We consider supersymmetry in five dimensions, where the fermionic parameters are a 2‐form under . Supermultiplets are investigated using the pure spinor superfield formalism, and are found to be closely related to infinite‐dimensional extensions of the supersymmetry algebra: the Borcherds superalgebra , the tensor hierarchy algebra and the ...

A toolkit for twisted chiral superfields [PDF]
Journal of High Energy Physics, 2020 Abstract We calculate the most general terms for arbitrary Lagrangians of twisted chiral superfields in 2D (2,2) supersymmetric theories [1]. The scalar and fermion kinetic terms and interactions are given explicitly. We define a set of twisted superspace coordinates, which allows to obtain Lagrangian terms for generic Kähler potential and generic ...

Towards the n-point one-loop superstring amplitude. Part I. Pure spinors and superfield kinematics [PDF]
Journal of High Energy Physics, 2018 This is the first installment of a series of three papers in which we describe a method to determine higher-point correlation functions in one-loop open-superstring amplitudes from first principles.

Fortschritte der Physik, Volume 69, Issue 10, October 2021., 2021 Abstract We develop a three‐dimensional theory of rigid supersymmetry describing the dynamics of a set of hypermultiplets on a curved AdS3 worldvolume background, whose supersymmetry is captured by the supergroup . To unveil some remarkable features of this model, we perform two twists, involving the SL factors of the theory. After the first twist, our

Superspace formulation of exotic supergravities in six dimensions
Journal of High Energy Physics, 2021 We provide a linearised superfield description of the exotic non-metric N = (4, 0) supergravity in D = 6, by using a pure spinor superfield formalism. The basic field Ψ is a ghost number 2 scalar, transforming in the same R-symmetry module as the tensor ...

Double Copy from Homotopy Algebras
Fortschritte der Physik, Volume 69, Issue 8-9, September 2021., 2021 It will be shown that the BRST Lagrangian double copy construction of N = 0 supergravity as the ‘square’ of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. The authors significantly expand on their previous work arguing the validity of the double copy at the loop level, and they give a detailed derivation of the double ...

On structure of effective action in four-dimensional quantum dilaton supergravity [PDF]
, 1996 A general structure of effective action in new chiral superfield model associated with $N=1$, $D=4$ supergravity is investigated. This model corresponds to finite quantum field theory and does not demand the regularization and renormalization at ...

Reparameterization Invariant Model of a Supersymmetric System: BRST and Supervariable Approaches
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We carry out the Becchi‐Rouet‐Stora‐Tyutin (BRST) quantization of the one (0 + 1)‐dimensional (1D) model of a free massive spinning relativistic particle (i.e., a supersymmetric system) by exploiting its classical infinitesimal and continuous reparameterization symmetry transformations.
