Primordial gravity wave background anisotropies
Vasyl Alba, Juan Maldacena
We consider the primordial gravity wave background produced by inflation. We compute the small anisotropy produced by the primordial scalar fluctuations.
Constraining conformal field theories with a higher spin symmetry in d> 3 dimensions
Vasyl Alba, Kenan Diab
We study unitary conformal field theories with a unique stress tensor and at least one higher-spin conserved current in d>3 dimensions. We prove that every such theory contains an…
Constraining conformal field theories with a higher spin symmetry in d=4
Vasyl Alba, Kenan Diab
We study unitary conformal field theories with a unique stress tensor and at least one higher-spin conserved current in four dimensions. We prove that every such theory contains an…
On combinatorial expansion of the conformal blocks arising from AGT conjecture
V. A. Alba, V. A. Fateev, A. V. Litvinov +1
In their recent paper \cite{Alday:2009aq} Alday, Gaiotto and Tachikawa proposed a relation between four-dimensional supersymmetric gauge theories and two-dimensiona…
Check of AGT Relation for Conformal Blocks on Sphere
V. Alba, And. Morozov
The AGT conjecture identifying conformal blocks with the Nekrasov functions is investigated for the spherical conformal blocks with more than 4 external legs. The diagram technique…
