Nonstandard Higgs decays in the E6 inspired SUSY models

R. Nevzorov, S. Pakvasa

We consider the exotic decays of the SM-like Higgs state within the E6 inspired supersymmetric (SUSY) models. In these models the lightest SUSY particle (LSP) can be substantially…

Charged mediators in dark matter scattering with nuclei and the strangeness content of nucleons: Strange Brew

Chris Kelso, Jason Kumar, Pearl Sandick +1

We consider a scenario, within the framework of the MSSM, in which dark matter is bino-like and dark matter-nucleon spin-independent scattering occurs via the exchange of light squ…

Monojet plus soft dilepton signal from light higgsino pair production at LHC14

Howard Baer, Azar Mustafayev, Xerxes Tata

Naturalness arguments imply the existence of higgsinos lighter than 200-300 GeV. However, because these higgsinos are nearly mass degenerate, they release very little visible energ…

Flavor ratios of extragalactical neutrinos and neutrino shortcuts in extra dimensions

Elke Aeikens, Heinrich Päs, Sandip Pakvasa +1

The recent measurement of high energy extragalactic neutrinos by the IceCube Collaboration has opened a new window to probe non-standard neutrino properties. Among other effects, s…

MSSM dark matter and a light slepton sector: The Incredible Bulk

Keita Fukushima, Chris Kelso, Jason Kumar +2

Recent experimental results from the LHC have placed strong constraints on the masses of QCD-charged superpartners. The MSSM parameter space is also constrained by the measurement…

A New Direction in Dark-Matter Complementarity: Dark-Matter Decay as a Complementary Probe of Multi-Component Dark Sectors

Keith R. Dienes, Jason Kumar, Brooks Thomas +1

In single-component theories of dark matter, the amplitudes for dark-matter production, annihilation, and scattering can be related to each other through various crossing…

Physics at a Higgsino Factory

Howard Baer, Vernon Barger, Dan Mickelson +2

Naturalness arguments applied to supersymmetric theories imply a spectrum containing four light higgsinos \tz_{1,2} and \tw_1^+- with masses ~ 100-300 GeV (the closer to M_Z the mo…

Complementary Constraints on Light Dark Matter from Heavy Quarkonium Decays

Nicolas Fernandez, Jason Kumar, Ilsoo Seong +1

We investigate constraints on the properties of light dark matter which can be obtained from analysis of invisible quarkonium decays at high intensity electron-positron colliders i…

Supersymmetry, Naturalness, and Light Higgsinos

Azar Mustafayev, Xerxes Tata

We compare and contrast three different sensitivity measures, , and that have been used in discussions of fine-tuning. We argue that though…

S-dual Inflation: BICEP2 data without unlikeliness

Luis A. Anchordoqui, Vernon Barger, Haim Goldberg +2

We show that S-dual inflationary potentials solve the unlikeliness problem manifested in Planck data and explain the excess B-mode power observed by the BICEP2 experiment as arisin…

Monojets and mono-photons from light higgsino pair production at LHC14

Howard Baer, Azar Mustafayev, Xerxes Tata

Naturalness arguments imply the existence of higgsinos lighter than 200-300 GeV. However, because these higgsinos are nearly mass degenerate, they release very little visible energ…

Effects of Neutrino Inverse Seesaw Mechanism on the Sparticle Spectrum in CMSSM and NUHM2

I. Gogoladze, B. He, A. Mustafayev +2

We study the implications of the inverse seesaw mechanism (ISS) on the sparticle spectrum in the Constrained Minimal Supersymmetric Standard Model (CMSSM) and Non-Universal Higgs M…
