Radiatively-driven Natural Supersymmetry
(2014-08-15)
Within the framework of supersymmetric theories, a question arises: how can the W, Z, and h masses be so low (∼ 100 GeV) when the superpartner masses are so high (mSUSY > 1−2 TeV)? This is the little hierarchy problem, and ...
Co-Spatial UV-Optical HST/STIS Spectra of Seven Galactic Planetary Nebulae: Nebular and Stellar Properties
(2017)
This project had two main goals: (1) to investigate to what extent planetary nebulae (PNe) are chemically homogeneous; and (2) to provide physical constraints on the central star properties of each PN. The first goal was ...
Naturalness in Supersymmetry
(2015-06)
Weak scale supersymmetry solves the Big Hierarchy problem of the Standard Model. But recent severe sparticle mass limits from the LHC accentuate the Little Hierarchy Problem: Why are the W , Z and h masses so small (∼ 100 ...
