Electroweak resummation of neutralino dark-matter annihilation into high-energy photons

open access: yesJournal of High Energy Physics, 2023
We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with (TeV) mass to high-energy photons in the minimal supersymmetric standard model, extending previous work on the minimal wino and Higgsino models.

Wino dark matter and future dSph observations [PDF]

open access: yesJournal of High Energy Physics, 2014
We discuss the indirect detection of the wino dark matter utilizing gamma-ray observations of dwarf spheroidal galaxies (dSphs). After carefully reviewing current limits with particular attention to astrophysical uncertainties, we show prospects of the wino mass limit in future gamma-ray observation by the Fermi-LAT and the GAMMA-400 telescopes.

MSSM Dark Matter in Light of Higgs and LUX Results

open access: yesAdvances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
The constraints imposed on the Minimal Supersymmetric Standard Model (MSSM) parameter space by the Large Hadron Collider (LHC) Higgs mass limit and gluino mass lower bound are revisited. We also analyze the thermal relic abundance of lightest neutralino, which is the Lightest Supersymmetric Particle (LSP).

Phenomenological Hints from a Class of String Motivated Model Constructions

open access: yesAdvances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
We use string theory constructions towards the generalisation of the supersymmetric standard model of strong and electroweak interactions. Properties of the models depend crucially on the location of fields in extradimensional compact space. This allows us to extract some generic lessons for the phenomenological properties of the low energy effective ...

Muon g − 2 anomaly in anomaly mediation

open access: yesJournal 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

Exploring New Models in All Detail with SARAH

open access: yesAdvances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
I give an overview about the features the Mathematica package SARAH provides to study new models. In general, SARAH can handle a wide range of models beyond the MSSM coming with additional chiral superfields, extra gauge groups, or distinctive features like Dirac gaugino masses.

Interplay Between MW, ΩCDMh2, and (g − 2)μ in Flavor Symmetry–Based Supersymmetric Models

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
We study the phenomenological implications of the minimal supersymmetric standard model (MSSM) augmented by a nonabelian flavor symmetry labeled as sMSSM. Incorporating this flavor symmetry allows for a significant reduction in the original plethora of free parameters present in the MSSM, ultimately reducing them down to just seven in sMSSM.

Searches for Prompt R‐Parity‐Violating Supersymmetry at the LHC

open access: yesAdvances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
Searches for supersymmetry (SUSY) at the LHC frequently assume the conservation of R‐parity in their design, optimization, and interpretation. In the case that R‐parity is not conserved, constraints on SUSY particle masses tend to be weakened with respect to R‐parity‐conserving models.

Looking for a heavy wino LSP in collider and dark matter experiments [PDF]

open access: yes, 2007
We investigate the phenomenology of a wino LSP as obtained in AMSB and some string models. The WMAP constraint on the DM relic density implies a wino LSP mass of 2.0-2.3 TeV.
