Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity
Fortschritte der Physik, Volume 72, Issue 4, April 2024.Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar

The anti-de Sitter supergeometry revisited
Journal of High Energy PhysicsIn a supergravity framework, the N $$ \mathcal{N} $$ -extended anti-de Sitter (AdS) superspace in four spacetime dimensions, AdS 4 4 N $$ {\textrm{AdS}}^{4\left|4\mathcal{N}\right.} $$ , is a maximally symmetric background that is described by a curved ...

Octonionic Magical Supergravity, Niemeier Lattices, and Exceptional & Hilbert Modular Forms
Fortschritte der Physik, Volume 72, Issue 2, February 2024.Abstract The quantum degeneracies of Bogomolny‐Prasad‐Sommerfield (BPS) black holes of octonionic magical supergravity in five dimensions are studied. Quantum degeneracy is defined purely number theoretically as the number of distinct states in charge space with a given set of invariant labels.

Three dimensional canonical singularity and five dimensional N $$ \mathcal{N} $$ = 1 SCFT
Journal of High Energy Physics, 2017 We conjecture that every three dimensional canonical singularity defines a five dimensional N $$ \mathcal{N} $$ = 1 SCFT. Flavor symmetry can be found from singularity structure: non-abelian flavor symmetry is read from the singularity type over one ...

Scalar neutrino dark matter in U(1)XSSM
Journal of High Energy Physics, 2020 U(1) X SSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3) C × SU(2) L × U(1) Y × U(1) X . To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are added to MSSM.

On hydrogen-like bound states in N $$ \mathcal{N} $$ = 4 super Yang-Mills
Journal of High Energy Physics, 2017 Using relativistic quantum mechanics, we study the spectrum of a non-BPS two-particle bound state in the massive phase of N $$ \mathcal{N} $$ = 4 super Yang-Mills, in the limit when one of the particles is infinitely heavier than the other.

Goldstino superfields in N = 2 $$ \mathcal{N}=2 $$ supergravity
Journal of High Energy Physics, 2017 We present off-shell N = 2 $$ \mathcal{N}=2 $$ supergravity actions, which exhibit spontaneously broken local supersymmetry and allow for de Sitter vacua for certain values of the parameters. They are obtained by coupling the standard N = 2 $$ \mathcal{N}
