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.

, 2023 A large class of supergravities in diverse dimensions are surveyed. This includes maximal supergravities, their general gaugings in the framework of embedding tensor formalism, supergravities with less than maximal supersymmetry, their matter couplings and general gaugings.

Modified Supergravity Phenomenology in Gravitational Waves Era
Universe, 2022 We discuss phenomenological aspects of modified supergravity (MSG) in gravitational wave (GW) physics. MSG naturally provides double inflation and primordial black holes (PBHs) as cold dark matter.

Special Geometry and Space-time Signature [PDF]
, 2017 We construct N=2 four and five-dimensional supergravity theories coupled to vector multiplets in various space-time signatures (t,s), where t and s refer, respectively, to the number of time and spatial dimensions.

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.

Supersymmetric $$AdS_5$$ AdS5 black holes and strings from 5D $$N=4$$ N=4 gauged supergravity
European Physical Journal C: Particles and Fields, 2019 We study supersymmetric $$AdS_3\times \Sigma _2$$ AdS3×Σ2 and $$AdS_2\times \Sigma _3$$ AdS2×Σ3 solutions, with $$\Sigma _2=S^2,H^2$$ Σ2=S2,H2 and $$\Sigma _3=S^3,H^3$$ Σ3=S3,H3 , in five-dimensional $$N=4$$ N=4 gauged supergravity coupled to five vector

On the Geometric Approach to the Boundary Problem in Supergravity
Universe, 2021 We review the geometric superspace approach to the boundary problem in supergravity, retracing the geometric construction of four-dimensional supergravity Lagrangians in the presence of a non-trivial boundary of spacetime.

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.

Physics Letters B, 1986 Abstract The anomaly of the supercurrent of an abelian vector multiplet interacting with external supergravity is considered, and it is shown that it is equivalent to a gravitational anomaly. The local counterterms that reinstate the conservation of the supercurrent are exhibited.
