Refined Vafa-Witten invariants for toric surfaces from supersymmetric localization in 5D gauge theory
Osama Khlaif, Boris Pioline, Alessandro Tanzini
We study the partition function of five-dimensional supersymmetric Yang-Mills (SYM) theory with an adjoint hypermultiplet of mass on a toric KÃ…
On the Schubert calculus of the quantum K-theory for partial flag manifolds: a 3d A-model perspective
Zhihao Duan, Osama Khlaif, Hao Zou
We further investigate the 3d gauged linear sigma model (GLSM)/~quantum K-theory correspondence for partial flag manifolds . This is a 3d uplif…
Schubert line defects in 3d GLSMs, part I: Complete flag manifolds and quantum Grothendieck polynomials
Cyril Closset, Wei Gu, Osama Khlaif +3
We construct new half-BPS line defects in 3d supersymmetric quiver gauge theories whose Higgs branches are complete flag manifolds . Upon circle co…
Schubert line defects in 3d GLSMs, part II: Partial flag manifolds and parabolic quantum polynomials
Cyril Closset, Wei Gu, Osama Khlaif +3
We construct Schubert line defects in the 3d supersymmetric gauged linear sigma model (GLSM) with target space a partial flag manifold $X={\rm Fl}({\boldsymbol{k}};…
The 3d -model and generalised symmetries, Part I: bosonic Chern-Simons theories
Cyril Closset, Elias Furrer, Adam Keyes +1
The 3d -model is a two-dimensional approach to the computation of supersymmetric observables of three-dimensional supersymmetric gauge theories. In principle, it…
Aspects of 4d gauge theories from M-theory: decomposition, automorphisms, and generalised symmetries
Osama Khlaif, Marwan Najjar
We study the decomposition of 4d gauge theories with Lie algebras of type , , and , realized via M-theory geo…
