Infrared duality in unoriented Pseudo del Pezzo

Autor: Andrea Antinucci, Salvo Mancani, Fabio Riccioni

Publikováno v: Physics Letters B, Vol 811, Iss , Pp 135902- (2020)

We study the orientifold projections of the N=1 superconformal field theories describing D3-branes probing the Pseudo del Pezzo singularities PdP3b and PdP3c. The PdP3c parent theory admits two inequivalent orientifolds. Exploiting a maximization, we

Meson spectrum in SU(N) gauge theories with quarks in higher representations: A check of Casimir scaling hypothesis

Autor: Fabien Buisseret, Claude Semay

Publikováno v: Results in Physics, Vol 17, Iss , Pp 103057- (2020)

Gauge theories with gauge group SU(N) and quarks belonging to arbitrary representations of SU(N) form a rich landscape of QCD-like theories, whose study can shed new light on the properties of confinement. Four cases are particularly worth of interes

Flat F-theory and friends

Autor: Cheng, Peng, Melnikov, Ilarion V., Minasian, Ruben

We discuss F-theory backgrounds associated to flat torus bundles over Ricci-flat manifolds. In this setting the F-theory background can be understood as a IIB orientifold with a large radius limit described by a supersymmetric compactification of IIB

Non-Supersymmetric Vacua and Self-Adjoint Extensions

Autor: Mourad, J., Sagnotti, A.

Internal intervals spanned by finite ranges of a conformal coordinate $z$ and terminating at a pair of singularities are a common feature of many string compactifications with broken supersymmetry. The squared masses emerging in lower-dimensional Min

Anomalous and axial Z′ contributions to g−2

Autor: Pascal Anastasopoulos, Kunio Kaneta, Elias Kiritsis, Yann Mambrini

Publikováno v: Journal of High Energy Physics
Journal of High Energy Physics, 2023, 02 (2), pp.051. ⟨10.1007/JHEP02(2023)051⟩

We study the effects of an anomalous Z' boson on the anomalous magnetic moment of the muon (g-2), and especially the impact of its axial coupling. We mainly evaluate the negative contribution to (g-2) of such couplings at one-loop and look at the ano

Non-planar corrections in orbifold/orientifold $\mathcal N=2$ superconformal theories from localization

Journal of High Energy Physics, 2023, 05, pp.165. ⟨10.1007/JHEP05(2023)165⟩

We study non-planar corrections in two special $\mathcal N=2$ superconformal $SU(N)$ gauge theories that are planar-equivalent to $\mathcal N=4$ SYM theory: two-nodes quiver model with equal couplings and $\mathcal N=2$ vector multiplet coupled to tw

We study 4dN = 1 gauge theories engineered via D-branes at orientifolds of toric singularities, where gauge anomalies are cancelled without the introduction of non-compact flavor branes. Using dimer model techniques, we derive geometric criteria for

The large number of moduli fields arising in a generic string theory compactification makes a complete computation of the low energy effective theory infeasible. A common strategy to solve this problem is to consider Calabi-Yau manifolds with discret
