Twistor strings with flavour

We explore the tree-level description of a class of N = 2 UV-finite SYM the- ories with fundamental flavour within a topological B-model twistor string framework. In particular, we identify the twistor dual of the Sp(N) gauge theory with one antisymmetric and four fundamental hypermultiplets, as well as that of the SU(N) theory with 2N hy- permultiplets. This is achieved by suitably orientifolding/orbifolding the original N = 4 setup of Witten and adding a certain number of new topological…

Adding flavour to twistor strings
Twistor string theory is known to describe a wide variety of field theories at tree- level and has proved extremely useful in making substantial progress in perturbative gauge theory. We explore the
Heterotic twistor–string theory
Abstract We reformulate twistor–string theory as a heterotic string based on a twisted ( 0 , 2 ) model. The path integral localizes on holomorphic maps, while the ( 0 , 2 ) moduli naturally
MHV amplitudes in N=2 SQCD and in N=4 SYM at one loop
Using four-dimensional unitarity and MHV-rules we calculate the one-loop MHV amplitudes with all external particles in the adjoint representation for N=2 supersymmetric QCD with N_f fundamental
On SQCD with massive and massless flavors
We consider supersymmetric QCD in the free magnetic phase with massless and massive flavors. The theory has a supersymmetry breaking pseudo-moduli space of vacua and a runaway behavior far away from

Scattering of noncommutative waves and solitons in a supersymmetric chiral model in 2 + 1 dimensions
Interactions of noncommutative waves and solitons in 2 + 1 dimensions can be analyzed exactly for a supersymmetric and integrable U(n) chiral model extending the Ward model. Using the Moyal-deformed
Canonical description of the D = 10 superstring formulated in supertwistor space
Canonical description of the D = 10 superstring action involving supertwistor variables generalizing Penrose–Ferber supertwistors is developed. Primary and secondary constraints are identified and

MHV amplitudes, Wilson loops and the BDS ansatz in the superconformal N=2 QCD
This paper has been withdrawn by the author due to an error made in the analysis of MHV amplitudes with external fundamental matter fields in the superconformal N=2 SQCD.


Holography and the Higgs branch of N=2 SYM theories
We present a proposal for the description of the Higgs branch of four-dimensional N=2 super- symmetric Yang-Mills theories in the context of the AdS/CFT correspondence. We focus on a finite Sp(N) N=2
Marginal deformations of N=4 SYM from open/closed twistor strings
Abstract We investigate how the marginal deformations of N = 4 supersymmetric Yang–Mills theory (analysed in particular by Leigh and Strassler) arise within B-model topological string theory on
N=2 strings and the twistorial Calabi-Yau
We interpret the A and B model topological strings on CP^{3|4} as equivalent to open N=2 string theory on spacetime with signature (2,2), when covariantized with respect to SO(2,2) and
Orbifolding the twistor string
Abstract The D-instanton expansion of the topological B-model on the supermanifold CP ( 3 | 4 ) reproduces the perturbative expansion of N = 4 super-Yang–Mills theory. In this paper we consider

Instantons in N=2 Sp(N) superconformal gauge theories and the AdS/CFT correspondence
Abstract We study, using ADHM construction, instanton effects in an N =2 superconformal Sp(N) gauge theory, arising as effective field theory on a system of N D3-branes near an orientifold 7-plane

By analyzing F-theory on K3 near the orbifold limit of K3 we establish the equivalence between F-theory on K3 and an orientifold of type IIB on T2, which in turn is related by a T-duality
