Oblique confinement at θ≠0 in weakly coupled gauge theories with deformations (2017)
Journal Article
Anber, M. M., & Zhitnitsky, A. R. (2017). Oblique confinement at θ≠0 in weakly coupled gauge theories with deformations. Physical Review D, 96(7), Article 074022. https://doi.org/10.1103/physrevd.96.074022

The main focus of this work is to test the ideas related to the oblique confinement in a theoretically controllable manner using the “deformed QCD” as a toy model. We explicitly show that the oblique confinement in the weakly coupled gauge theories e... Read More about Oblique confinement at θ≠0 in weakly coupled gauge theories with deformations.

Exploring instantons in nonlinear sigma models with spin-lattice systems (2021)
Journal Article
Schenk, S., & Spannowsky, M. (2021). Exploring instantons in nonlinear sigma models with spin-lattice systems. Physical Review B, 103(14), Article 144436. https://doi.org/10.1103/physrevb.103.144436

Instanton processes are present in a variety of quantum field theories relevant to high energy as well as condensed matter physics. While they have led to important theoretical insights and physical applications, their underlying features often remai...

Poincaré series for modular graph forms at depth two. Part II. Iterated integrals of cusp forms (2022)
Journal Article
Dorigoni, D., Kleinschmidt, A., & Schlotterer, O. (2022). Poincaré series for modular graph forms at depth two. Part II. Iterated integrals of cusp forms. Journal of High Energy Physics, 2022(1), Article 134. https://doi.org/10.1007/jhep01%282022%29134

We continue the analysis of modular invariant functions, subject to inhomogeneous Laplace eigenvalue equations, that were determined in terms of Poincaré series in a companion paper. The source term of the Laplace equation is a product of (derivative... Read More about Poincaré series for modular graph forms at depth two. Part II. Iterated integrals of cusp forms.

Generalized ’t Hooft anomalies on non-spin manifolds (2020)
Journal Article
Anber, M. M., & Poppitz, E. (2020). Generalized ’t Hooft anomalies on non-spin manifolds. Journal of High Energy Physics, 2020(4), Article 97. https://doi.org/10.1007/jhep04%282020%29097

We study the mixed anomaly between the discrete chiral symmetry and general baryon-color-flavor (BCF) backgrounds in SU(Nc) gauge theories with Nf flavors of Dirac fermions in representations ℛc of N -ality nc, formulated on non-spin manifolds. We sh... Read More about Generalized ’t Hooft anomalies on non-spin manifolds.

Domain walls in high-T SU(N) super Yang-Mills theory and QCD(adj) (2019)
Journal Article
Anber, M. M., & Poppitz, E. (2019). Domain walls in high-T SU(N) super Yang-Mills theory and QCD(adj). Journal of High Energy Physics, 2019(5), Article 151. https://doi.org/10.1007/jhep05%282019%29151

We study the domain walls in hot 4-D SU(N) super Yang-Mills theory and QCD(adj), with nf Weyl flavors. We find that the k-wall worldvolume theory is 2-D QCD with gauge group SU(N − k) × SU(k) × U(1) and Dirac fermions charged under U(1) and transform...

Large-scale messengers from massive higher spin fields (2018)
Journal Article
Anber, M. M. (2018). Large-scale messengers from massive higher spin fields. Journal of High Energy Physics, 2018(6), Article 154. https://doi.org/10.1007/jhep06%282018%29154

We show that nonperturbative production of massive higher spin fields from vacuum will accompany the generation of non-vanishing macroscopic energy-momentum tensor correlators. This argument is based on the general causal field formalism, which gives... Read More about Large-scale messengers from massive higher spin fields.

Classification of compactified su(Nc) gauge theories with fermions in all representations (2017)
Journal Article
Anber, M. M., & Vincent-Genod, L. (2017). Classification of compactified su(Nc) gauge theories with fermions in all representations. Journal of High Energy Physics, 2017(12), Article 028. https://doi.org/10.1007/jhep12%282017%29028

We classify su(N c ) gauge theories on R3×S1 with massless fermions in higher representations obeying periodic boundary conditions along S1. In particular, we single out the class of theories that is asymptotically free and weakly coupled in the infr...
