What are the implications of supersymmetry generators satisfying a majorana condition?
hoping to resolve some confusion I have about this paper (https://arxiv.org/abs/hep-th/9904017) regarding the holographic dual of a flow from ${\cal N}=4$ SYM to an ${\cal N}=1$ SUSY theory.
Broadly ...

BPS States and Conditions: Definition and Significance in the Context of ADS/CFT
I am currently studying a paper similar to the one linked and I'm struggling to comprehend the concept of BPS (Bogomol'nyi-Prasad-Sommerfield) states/operators. The cited papers mention these terms ...

Dynkin labels of $psu(2,2|4)$
I'm currently studying the superconformal algebra $psu(2,2|4)$, but I'm having trouble understanding its representation.
Following arxiv:1012.4004
I know that the maximal compact subalgebra is su(2) $\...

Derivatives as "dynamical variables of the theory"?
This question will probably sounds very broad.
So, I work with classical general relativity, a bit of field theory and semiclassical gravity. I have a friend, though, that works with things like ...

What is the generally expected or more useful form of supersymmetry, on-shell or off-shell?
If the on-shell numbers of degrees of freedom of bosons and fermions match we
have on-shell supersymmetry, if the off-shell numbers match we have off-shell
supersymmetry. When LHC people say they are ...

Confusion about Generating Functionals in AdS/CFT
I have a question regarding an equation in the book "Gauge/Gravity Duality" by Martin Ammon and Johanna Erdmenger which however can also be found in other AdS/CFT books or lecture notes.
The ...

Can AdS/CFT still give bulk locality on small scales if the CFT has a nontrivial phase diagram?
The AdS/CFT correspondence is a well-supported conjecture about the equivalence between an ordinary conformal field theory (CFT) and a theory of quantum gravity in asymptotically anti-de Sitter (AdS) ...

What is a protected states in Supersymmetry, Superstring theory context
I know that they are the states that have protected scaling dimension when couplings are changed. But there are some states that are protected only in free orbifold theory, this is something I don't ...

What role does SUSY play in gauge/gravity duality?
This question arises in my project of finding the conformal field theory dual to the bosonic part of the Yang-Mills theory, i.e. non-supersymmetric large $N$ YM theory. Supersymmetry is a constant ...

Supersymmetry in AdS/CFT
In the original form of Maldacena's AdS/CFT, the bulk is classical supergravity and the boundary is superconformal field theory in the Maldacena's limit. However, in many applications of AdS/CFT, for ...

Can pure-bosonic string theories exist in curved spacetime?
Question: Can there be a consistent non-supersymmetric pure-bosonic string theory in some curved spacetimes?
Reason: Since fields with certain amount of negative mass can exist in curved spacetime (...

Supersymmetries of the type IIB D3-brane action
The following query is based on a reading of section 2.2 of a paper by Graña and Polchinski. The idea is to begin with the D3 brane action of the form
$$ ds^2 = Z^{-1/2}\eta_{\mu\nu}dx^\mu dx^\nu + Z^...

Moduli Space of $\mathcal{N}=4$ SYM on $\mathbb{R} \times S^3$
When we define $\mathcal{N}=4$ SYM on flat Minkowski space, the supersymmetric vacua are parametrized by scalars living in the cartan subalgebra of the gauge group. A generic point in the moduli space ...

What is the definition of a "UV-complete" theory?
I would like to know (1) what exactly is a UV-complete theory and (2) what is a confirmatory test of that?
Is asymptotic freedom enough to conclude that a theory is UV-complete?
Does it become ...

M(atrix) theory and things other than D0-branes? And is it non-peturbative M-theory or non-peturbative Type IIA theory?
When I first read the BFSS Paper on M(atrix)-theory, I was under the impression that it was a non-peturbative formulation of M-theory. But recently, upon reading this paper of Nathan Seiberg's, I ...
