Muon g − 2 anomaly in anomaly mediation
Journal of High Energy Physics, 2021 The long-standing muon g − 2 anomaly has been confirmed recently at the Fermilab. The combined discrepancy from Fermilab and Brookhaven results shows a difference from the theory at a significance of 4.2 σ. In addition, the LHC has updated the lower mass

Species Scale and Primordial Gravitational Waves
Fortschritte 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 ...

Perturbative $��$-Supersymmetry and Small $��$-Phenomenology [PDF]
The European Physical Journal C, 2014 For the minimal $ $-supersymmetry, it stays perturbative to the GUT scale for $ \leq 0.7$. This upper bound is relaxed when one either takes the criteria that all couplings close to $\sim 4 $ for non-perturbation or allows new fields at the intermediate scale between the weak and GUT scale.

Detection prospects of light pseudoscalar Higgs boson at the LHC
Journal of High Energy Physics, 2017 The discovery potential of light pseudo scalar Higgs boson for the mass range 10-60 GeV is explored. In the context of the next-to-minimal supersymmetric standard (NMSSM) model, the branching fraction of light pseudo scalar Higgs boson decaying to a pair

Proton decay: flipped vs. unflipped SU(5)
Journal of High Energy Physics, 2020 We analyze nucleon decay modes in a no-scale supersymmetric flipped SU(5) GUT model, and contrast them with the predictions for proton decays via dimension-6 operators in a standard unflipped supersymmetric SU(5) GUT model.

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity
Fortschritte 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

Phenomenological Aspects of F-theory
, 1997 Stabilizing a heterotic string vacuum with a large expectation value of the dilaton and simultaneously breaking low-energy supersymmetry is a long-standing problem of string phenomenology. We reconsider these issues in light of the recent developments in

Probing minimal SUSY scenarios in the light of muon g−2 and dark matter
Journal of High Energy Physics, 2017 We study supersymmetric (SUSY) models in which the muon g −2 discrepancy and the dark matter relic abundance are simultaneously explained. The muon g − 2 discrepancy, or a 3σ deviation between the experimental and theoretical results of the muon ...

Fortschritte der Physik, Volume 72, Issue 2, February 2024.Abstract The string theory landscape may include a multitude of ultraviolet embeddings of the Standard Model, but identifying these has proven difficult due to the enormous number of available string compactifications. Genetic Algorithms (GAs) represent a powerful class of discrete optimisation techniques that can efficiently deal with the immensity of
