Flavor in SU(5)$SU(5)$ Finite Grand Unified Models

open access: yesFortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum at s√=8 TeV proton-proton collisions using the ATLAS experiment [PDF]

open access: yes, 2013
A search is presented for new particles decaying to large numbers (7 or more) of jets, with missing transverse momentum and no isolated electrons or muons. This analysis uses 20.3 fb−1 of pp collision data at s√=8 TeV collected by the ATLAS experiment at

Type-II 2HDM under the precision measurements at the Z-pole and a Higgs factory

open access: yesJournal of High Energy Physics, 2019
Future precision measurements of the Standard Model (SM) parameters at the proposed Z-factories and Higgs factories may have significant impacts on new physics beyond the Standard Model in the electroweak sector.

Species Scale and Primordial Gravitational Waves

open access: yesFortschritte der Physik, Volume 72, Issue 6, June 2024.
Abstract The species scale is a field‐dependent UV cut‐off for any effective field theory weakly coupled to gravity. In this letter, it is shown that in the context of inflationary cosmology, a detection of primordial gravitational waves will set an upper bound on the decay rate |Λs′/Λs|$|\Lambda ^{\prime }_s/\Lambda _s|$ of the species scale ...

Phenomenological consequences of supersymmetry with anomaly induced masses [PDF]

open access: yesNuclear Physics B, 1999
In the supersymmetric standard model there exist pure gravity contributions to the soft mass parameters which arise via the superconformal anomaly. We consider the low-energy phenomenology with a mass spectrum dominated by the anomaly-induced contributions.

Degrees of Metastability in Gauge Mediated Supersymmetry Breaking [PDF]

open access: yes, 2011
This thesis consists of an investigation into supersymmetry and its breaking. Emphasis is placed on the question of metastability and the role of non-topological solitons in the hidden sector.

Heavy Higgs as a portal to the supersymmetric electroweak sector

open access: yesJournal of High Energy Physics, 2019
The electroweak sector of the Minimal Supersymmetric Standard Model (MSSM) — neutralinos, charginos and sleptons — remains relatively weakly constrained at the LHC due in part to the small production cross sections of these particles.

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity

open access: yesFortschritte der Physik, Volume 72, Issue 4, April 2024.
Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar
