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

Phenomenological implications of supersymmetry breaking by the dilaton [PDF]

open access: yesPhysics Letters B, 1993
We investigate the low energy properties of string vacua with spontaneously broken $N=1$ supersymmetry by a dilaton $F$-term. As a consequence of the universal couplings of the dilaton, the supersymmetric mass spectrum is determined in terms of only three independent parameters and more constrained than in the minimal supersymmetric Standard Model. For

Relaxing the W′ Constraint on Compact Extradimension

open access: yesAdvances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
In this paper, we study the constraint on brane tension and compactification scale for models with brane fluctuations using the results from the direct search of W′ at 13 TeV LHC, with an integrated luminosity of 36.1fb−1, in the case for which branon forms the entire cold dark matter.

The light sgoldstino phenomenology: explanations for the muon (g − 2) deviation and KOTO anomaly

open access: yesJournal of High Energy Physics, 2020
In this work, we study the long-standing experimental anomaly in muon (g −2) and also recent anomalous excess in K L → π 0 + v v ¯ $$ {K}_L\to {\pi}^0+v\overline{v} $$ at the J-PARC KOTO experiment with sgoldstino.

Resummation of terms enhanced by trilinear squark-Higgs couplings in the MSSM

open access: yesJournal of High Energy Physics, 2021
We analyze the appearance of the trilinear squark-Higgs couplings x q in Green functions in the Higgs sector of the MSSM and in threshold corrections to the SM. The results are constraints on maximal powers of x q in QCD-related loop corrections.

Tachyonic de Sitter Solutions of 10d Type II Supergravities

open access: yesFortschritte der Physik, Volume 69, Issue 7, July 2021., 2021
Abstract Cosmological models of the early or late universe exhibit (quasi) de Sitter space‐times with different stability properties. Considering models derived from string theory, the swampland program does not provide for now a definite characterisation of this stability.

Data-driven analysis of a SUSY GUT of flavour

open access: yesJournal of High Energy Physics, 2022
We present a data-driven analysis of a concrete Supersymmetric (SUSY) Grand Unified Theory (GUT) of flavour, based on SU(5) × S 4, which predicts charged fermion and neutrino mass and mixing, and where the mass matrices of both the Standard Model and the

The current status of fine-tuning in supersymmetry

open access: yesJournal of High Energy Physics, 2020
In this paper, we minimize and compare two different fine-tuning measures in four high-scale supersymmetric models that are embedded in the MSSM. In addition, we determine the impact of current and future dark matter direct detection and collider ...

A singular way to search for heavy resonances in missing energy events

open access: yesJournal of High Energy Physics, 2020
The phase space of visible particles in missing energy events may have singularity structures. The singularity variables are devised to capture the singularities effectively for given event topology.
