Top Quark Flavor Changing Couplings at a Muon Collider
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.

Exploring New Models in All Detail with SARAH
Advances 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.

Renormalization of the SMEFT to dimension eight: Fermionic interactions I
Journal of High Energy PhysicsThis is the third of a series of works [1, 2] aimed at renormalizing the Standard Model effective field theory at one loop and to order 1/Λ4, with Λ being the new physics cut-off.

Solutions to axion electromagnetodynamics and new search strategies of sub-μeV axion
Journal of High Energy Physics, 2023 The Witten effect implies the electromagnetic interactions between axions and magnetic monopoles, and the quantum electromagnetodynamics (QEMD) properly describes interactions of electric charges, magnetic charges and photons.

One-loop matching of scotogenic model onto standard model effective field theory up to dimension 7
Journal of High Energy Physics, 2022 The scotogenic neutrino seesaw model is a minimal extension of the standard model with three ℤ 2-odd right-handed singlet fermions N and one ℤ 2-odd Higgs doublet η that can accommodate the tiny neutrino mass and provide a dark matter candidate in a ...

Probing dimension-8 SMEFT operators through neutral meson mixing
Journal of High Energy PhysicsWe investigate the impact of effective interactions of dimension-8 (dim-8) operators in the standard model effective field theory (SMEFT) on neutral meson mixing, focusing on the K 0 − K ¯ 0 $$ {K}^0-{\overline{K}}^0 $$ , B d , s − B ¯ d , s $$ {B}_{d,s}-

Revisiting CMSSM with non-universal gaugino masses under current constraints
Journal of High Energy PhysicsTo address the longstanding tension between the Constrained Minimal Supersymmetric Standard Model (CMSSM) and recent experimental data, we investigate non-universal gaugino masses within an SU(5) Grand Unified Theory (GUT) framework, focusing on the g ~ $

Exploring the BSM parameter space with neural network aided Simulation-Based Inference
Journal of High Energy PhysicsSome of the issues that make sampling parameter spaces of various beyond the Standard Model (BSM) scenarios computationally expensive are the high dimensionality of the input parameter space, complex likelihoods, and stringent experimental constraints ...

Searches for power-law warped extra dimensions
Journal of High Energy PhysicsExtra dimensions with a bulk dilaton field can be power-law warped, unlike the exponential warping in the Randall-Sundrum (RS) model. We show that this mildly warped extra dimension can address the hierarchy problem with a novel Kaluza-Klein (KK ...
