Journal of High Energy Physics, 2020 We present an improved calculation of the light CP-even Higgs boson pole mass in the MSSM based on the FlexibleEFTHiggs hybrid method. The calculation resums large logarithms to all orders and includes power-suppressed terms at fixed order. It uses state-

Exploring the nearly degenerate stop region with sbottom decays
Journal of High Energy Physics, 2017 A light stop with mass almost degenerate with the lightest neutralino has important connections with both naturalness and dark matter relic abundance. This region is also very hard to probe at colliders.

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.

Phenomenology of Low-Scale Supersymmetry Breaking Models [PDF]
Modern Physics Letters A, 2003 In this review we consider the distinctive phenomenology of supersymmetric models in which the scale of SUSY breaking is very low, [Formula: see text], focusing on the Higgs sector and the process of electroweak breaking. Using an effective Lagrangian description of the interactions between the observable fields and the SUSY breaking sector, it is ...

Explaining electron and muon g − 2 anomaly in SUSY without lepton-flavor mixings
Journal of High Energy Physics, 2019 We propose a SUSY scenario to explain the current electron and muon g − 2 discrepancies without introducing lepton flavor mixings. Threshold corrections to the Yukawa couplings can enhance the electron g − 2 and flip the sign of the SUSY contributions ...

Resonant Higgs pair production as a probe of stop at the LHC
Journal of High Energy Physics, 2017 Searching for top squark (stop) is a crucial task of the LHC. When the flavor conserving two body decays of the stop are kinematically forbidden, the stops produced near the threshold will live long enough to form bound states which subsequently decay ...

Mass hierarchy from the flavor symmetry in supersymmetric multi-Higgs doublet model
Journal of High Energy Physics, 2020 We study the supersymmetric standard model with multiple Higgs doublets with gauged U(1) X flavor symmetry. When the flavor symmetry is broken by the vacuum expectation value of flavon, the ℤ3 symmetry M 3 called matter triality remains and it prohibits ...
