Gravity in spacetimes with cosmological constants [PDF]

, 2009
This thesis is composed of two parts: gravity in the spacetime with a negative/positive cosmological constant. The first part, which is the negative case, devotes to constructing the IIB supergravity dual solution in AdS/CFT correspondence for N = (1, 0)

Embedding formalism for AdS superspaces in five dimensions

Journal of High Energy Physics
The standard geometric description of d-dimensional anti-de Sitter (AdS) space is a quadric in ℝ d−1,2 defined by (X 0)2 − (X 1)2 − ⋯ − (X d−1)2 + (X d )2 = ℓ 2 = const.

Nonlinear σ models with extended supersymmetry in four dimensions [PDF]

, 1980
Two nonlinear σ models are discussed which have N=2 supersymmetry in four dimensions. The first is globally supersymmetric on a noncompact field manifold.

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.

On quantum compatibility of counterterm deformations and duality symmetries in N≥5 $$ \mathcal{N}\ge 5 $$ supergravities

Journal of High Energy Physics, 2018
In N=5 $$ \mathcal{N}=5 $$, 6, 8 supergravities there are hidden symmetries of equations of motion, described by duality groups SU(1, 5), SO*(12), E 7(7) respectively.

Extended Supersymmetry and Four Dimensional Geometry [PDF]

, 2014
Semichiral ( 2 ; 2 ) sigma models with 4 d target space are discussed. A novel description in ( 1 ; 1 ) superspace allows an analysis of possible extended supersymmetries.

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 ...

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}

Improved Higgs naturalness with or without supersymmetry [PDF]

, 2006
Many models of electroweak symmetry-breaking with an extended Higgs sector exhibit improved naturalness, wherein the new physics scale, at which quadratic divergences of Higgs mass parameters due to top quark loops are cut off, can be pushed beyond the ...

The dark side of double-tensor multiplets

Journal of High Energy Physics
We explore the properties of a set of free double-tensor multiplets in N $$ \mathcal{N} $$ = 2 supersymmetry, focusing on their behavior within rigid superspace.
