On deformations and supersymmetry
Marco Baggio, Alessandro Sfondrini, Gabriele Tartaglino-Mazzucchelli +1
We investigate the "" deformations of two-dimensional supersymmetric quantum field theories. More precisely, we show that, by using the conservation equations for the sup…
Strings on NS-NS Backgrounds as Integrable Deformations
Marco Baggio, Alessandro Sfondrini
We consider the worldsheet S matrix of superstrings on an AdS3xS3xT4 NS-NS background in uniform light-cone gauge. We argue that scattering is given by a CDD factor that is non-tri…
Decoding a Three-Dimensional Conformal Manifold
Marco Baggio, Nikolay Bobev, Shai M. Chester +2
We study the one-dimensional complex conformal manifold that controls the infrared dynamics of a three-dimensional supersymmetric theory of three chiral superfields…
Aspects of Berry phase in QFT
Marco Baggio, Vasilis Niarchos, Kyriakos Papadodimas
When continuous parameters in a QFT are varied adiabatically, quantum states typically undergo mixing---a phenomenon characterized by the Berry phase. We initiate a systematic anal…
Protected string spectrum in AdS3/CFT2 from worldsheet integrability
Marco Baggio, Olof Ohlsson Sax, Alessandro Sfondrini +2
We derive the protected closed-string spectra of AdS3/CFT2 dual pairs with 16 supercharges at arbitrary values of the string tension and of the three-form fluxes. These follow imme…
Large-N correlation functions in superconformal QCD
Marco Baggio, Vasilis Niarchos, Kyriakos Papadodimas +1
We study extremal correlation functions of chiral primary operators in the large-N SU(N) superconformal QCD theory and present new results based on supersymmetric lo…
On exact correlation functions in SU(N) superconformal QCD
Marco Baggio, Vasilis Niarchos, Kyriakos Papadodimas
We consider the exact coupling constant dependence of extremal correlation functions of chiral primary operators in 4d superconformal gauge theories w…
Higher spins in the symmetric orbifold of K3
Marco Baggio, Matthias R. Gaberdiel, Cheng Peng
The symmetric orbifold of K3 is believed to be the CFT dual of string theory on AdS3 x S3 x K3 at the tensionless point. For the case when the K3 is described by the orbifold T4/Z2…
Exact correlation functions in SU(2) N=2 superconformal QCD
Marco Baggio, Vasilis Niarchos, Kyriakos Papadodimas
We report an exact solution of 2- and 3-point functions of chiral primary fields in SU(2) N=2 super-Yang-Mills theory coupled to four hypermultiplets. It is shown that these correl…
equations, localization and exact chiral rings in 4d N=2 SCFTs
Marco Baggio, Vasilis Niarchos, Kyriakos Papadodimas
We compute exact 2- and 3-point functions of chiral primaries in four-dimensional N=2 superconformal field theories, including all perturbative and instanton contributions. We demo…
Higher Derivative Corrections and Central Charges from Wrapped M5-branes
Marco Baggio, Nick Halmagyi, Daniel R. Mayerson +2
We compute four-derivative corrections to the AdS supergravity actions arising from the near-horizon geometry of N M5-branes wrapped on either one or two Riemann surfaces. This set…
Conformal Symmetry for Black Holes in Four Dimensions and Irrelevant Deformations
Marco Baggio, Jan de Boer, Juan I. Jottar +1
It has been argued several times in the past that the structure of the entropy formula for general non-extremal asymptotically flat black holes in four dimensions can be understood…
A non-renormalization theorem for chiral primary 3-point functions
Marco Baggio, Jan de Boer, Kyriakos Papadodimas
In this note we prove a non-renormalization theorem for the 3-point functions of 1/2 BPS primaries in the four-dimensional N = 4 SYM and chiral primaries in two dimensional N =(4,4…
Anomalous Breaking of Anisotropic Scaling Symmetry in the Quantum Lifshitz Model
Marco Baggio, Jan de Boer, Kristian Holsheimer
In this note we investigate the anomalous breaking of anisotropic scaling symmetry in a non-relativistic field theory with dynamical exponent z=2. On general grounds, one can show…
Hamilton-Jacobi Renormalization for Lifshitz Spacetime
Marco Baggio, Jan de Boer, Kristian Holsheimer
Just like AdS spacetimes, Lifshitz spacetimes require counterterms in order to make the on-shell value of the bulk action finite. We study these counterterms using the Hamilton-Jac…
