Double Copy From Tensor Products of Metric BV■‐Algebras

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

Stable de Sitter vacua in N=2, D=5 supergravity

, 2005
We find 5D gauged supergravity theories exhibiting stable de Sitter vacua. These are the first examples of stable de Sitter vacua in higher-dimensional (D>4) supergravity.

D=4, N=2 Supergravity with Abelian electric and magnetic charges [PDF]

, 2004
We discuss the relation between standard N=2 supergravity with translational gauging and N=2 supergravities with scalar-tensor multiplets with massive tensors and Abelian electric charges.

F-term multi-field inflation in supergravity without stabiliser superfields

Journal of High Energy Physics
Realising F -term slow-roll inflation in supergravity is non-trivial due to the well-known η-problem. The common strategy to solve the problem is to impose a shift symmetry on the Kähler potential, but this often leads to a negative potential in the ...

Sen's mechanism for self-dual super Maxwell theory

Nuclear Physics B
In several elementary particle scenarios, self-dual fields emerge as fundamental degrees of freedom. Some examples are the D=2 chiral boson, D=10 Type IIB supergravity, and D=6 chiral tensor multiplet theory.

Geometric Relational Framework for General‐Relativistic Gauge Field Theories

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract It is recalled how relationality arises as the core insight of general‐relativistic gauge field theories from the articulation of the generalized hole and point‐coincidence arguments. Hence, a compelling case for a manifestly relational framework ensues naturally.

On sgoldstino-less supergravity models of inflation [PDF]

, 2014
We go a step further in the search for a consistent and realistic supergravity model of large-field inflation by building a class of models with the following features: during slow-roll, all the scalar fields other than the inflaton are frozen by large ...

Linearised actions for N $$ \mathcal{N} $$ -extended (higher-spin) superconformal gravity

Journal of High Energy Physics, 2019
The off-shell actions for N $$ \mathcal{N} $$ -extended conformal supergravity theories in three dimensions were formulated in [1, 2] for 1 ≤ N $$ \mathcal{N} $$ ≤ 6 using a universal approach.

New higher derivative action for tensor multiplet in N $$ \mathcal{N} $$ = 2 conformal supergravity in four dimensions

Journal of High Energy Physics, 2020
We will use the covariant superform approach to develop a new density formula for N $$ \mathcal{N} $$ = 2 conformal supergravity which is based on a fermionic multiplet whose lowest component is a dimension-5/2 spinor.

Interplay Between MW, ΩCDMh2, and (g − 2)μ in Flavor Symmetry–Based Supersymmetric Models

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We study the phenomenological implications of the minimal supersymmetric standard model (MSSM) augmented by a nonabelian flavor symmetry labeled as sMSSM. Incorporating this flavor symmetry allows for a significant reduction in the original plethora of free parameters present in the MSSM, ultimately reducing them down to just seven in sMSSM.
